BRACKETWELD Project: successfully ultrasound welding through thermoplastic films


Bracketweld project has been running for already two years time (see link). During this period CIDAUT has developed a methodology to adjust the welding parameters, and a methodology to evaluate the performance of the welded brackets. In this process, different surface media have been evaluated selecting the most appropriate one based on different criteria.


The joint between the bracket and the thermosetting composite laminate (having a suitable surface media) will have two joint interfaces: one thermoplastic/thermoplastic interface, developed during the ultrasonic welding process, and one thermoplastic/thermosetting interface, developed during the co-curing of the thermosetting composite laminate with the thermoplastic surface media. Generally, the joint strength of the global bracket-to-component assembly will be limited by the weakest of the two interfaces:

Weld strength at the thermoplastic-thermoplastic interface developed through the ultrasonic welding which depends on the compatibility of the base materials of the thermoplastic bracket and thermoplastic surface media.

Bond strength at the thermoplastic-thermosetting interface developed through the co-curing process depends on the compatibility between the thermoplastic surface media and the thermosetting prepreg.

During the first part of the project, two different test were defined and set up to evaluate these strengths. Additionally, the evaluation of materials compatibility includes complementary laboratory tests like calorimetry (DSC), rheology (MFI) and microscopy that provide valuable information in order to better understand the results from the mechanical compatibility tests

In terms of surface media, different commercial references have been studied; research activities have included the selection/development of a suitable material formulation and the optimization of surface media parameters like thickness and morphology (porosity).

Regarding thickness, the thickness of thermoplastic films was optimized. Regarding morphology, the advantages of using additive manufactured plates were evaluated.

CIDAUT also developed its own surface media to evaluate material blends different from those available commercially.


CIDAUT and Valladolid City Council attend the second local workshop of the FCH regions and cities initiative in Santander

The Regions & Cities initiative ( is conducting a second round of workshops across Europe. The workshops are aimed to promote knowledge exchange on best practices in FCH project development and to discuss the way followed by European cities and regions to implement FCH projects.

fch_1 Welcome and introduction to the workshop by Roland Berger team and Jorge Muyo from Government of Cantabria

After the successful first round of workshops with many interesting discussions and learnings, a second round has been conducted in various European cities in April 2018. This time, in Spain, it was held in Santander on April 24 at the Science and Technology Park of Cantabria. CIDAUT and Valladolid City Council attended the workshop as stakeholders of the initiative.

The meeting started with the welcome from Jorge Muyo, Director of Innovation, Technological Development and Industrial Entrepreneurship of the Goverment of Cantabria. It continued with the presentation of the main objectives by Roland Berger team, highlighting the exchange of experiences and lessons learnt on key topics in FCH projects under development. As experts in this type of projects, a review of best practices in implementing FCH projects was carried out. It was remark the importance of creating conducive framework conditions with soft measures and policies, scoping local FCH project concepts (key elements and success factors) and engaging local stakeholders with a proper management.

The workshop was attended by Carlos Navas as representative of the FCHJU who conducted a presentation on Hydrogen in Spain. He stressed that in order to achieve the CO2 emission reductions established in the 2040-2050 scenarios, decarbonisation measures necessarily pass through hydrogen technologies, especially in the transport and industry sectors. Taking into account the hydrogen economy: hydrogen allows more renewables in the energy system and enables sector-coupling. He highlighted the 7 roles for hydrogen in the energy transition.

During the day, legal possibilities in order to obtain an end-of-waste consideration were highlighted. The European Commission has already set down end-of-waste criteria for glass, metal and copper scrap and criteria for various other materials that are under development. This latter aspect, end-of-waste concept, is regarded as a first step toward these materials to be considered as raw materials for other processes more than as a waste that have to be managed.

Certification processes around Circular Economy were also reviewed which are an important tool for enterprises to demonstrate its actual commitment with Circular Economy.

Finally, there was a time for exchanging information about existing positive experiences on waste re-used within Castilla y León, mainly related with the agri-food sector.

The MOVBIO project goes one step further

A new meeting was held to monitor the MOVBIO project in the facilities of the Center for Waste Valorisation (CVR) in Guimarães (Portugal) on January 18th and partners of Portugal and Spain with representatives of all project activities attended the meeting. The progress of the project in the study of the potential of pruning biomass for energy use in the north of Portugal and Castilla-León was shown. One of the purposes of the meeting was to establish the contents of the project’s website ( and the following milestones of the project aimed at preparing the final biomass potential report. The definition of case studies in which to validate the use of this biomass and the interaction with other projects related to the use of pruning such as the UP-running and BIOMASA-AP projects was also evaluated.


This meeting was completed the next day with a technical conference that included a demonstration in the field. It was possible to verify the pruning techniques of actinidia (kiwi) and of the vine, as well as its collection in the field for future energy use. Both species present a great potential in the north of Portugal and are of great interest in the scope of the MOVBIO project.


This project is co-financed by the programme of cooperation INTERREG V-A Spain-Portugal (POCTEP) 2014-2020 and will run until December 2019.

Cidaut and Valladolid City Council attend the first local workshop of the FCH regions and cities initiative

FCH Regions and cities initiative ( has set a series of workshops of the in different cities throughout in February- March 2018. The first one took place the 14th of February in Puertollano (Spain) in the National Centre of Hydrogen facilities. CIDAUT and Valladolid City Council had the opportunity to assist as part of the consortium of the initiative.


The workshop was attended by the mayor of Puertollano, Mayte Fernández, who together with the Minister of Economy of Castilla La Mancha, Patricia Franco, welcomed the opening of the Congress. Both stressed that the workshop was a good opportunity to expose the great potential of hydrogen in terms of energy. Emilio Nieto as Director of the National Centre of Hydrogen made an introduction to give way to the beginning of the workshop.

The workshop also had the presence of Enrique Girón as a representative of the FCHJU who kindly attended to all the doubts of the attendees regarding the initiative, as well as other issues related to projects financing. During the whole workshop the debate was moderated by the Roland Berger consultancy as coordinators of the initiative.

The different speakers were exposing the opportunities of hydrogen as an alternative energy source. Thus, Guillermo Figueruelo of the Hidrogeno Aragón Foundation presented the different projects they are involved such as HyER and BIGH2IT.

Carlos Funez presented the projects on hydrogen generation, hydrogen refuelling stations and the promotion of hydrogen vehicles from the point of view of CNH2 and INDHO. Jose Antonio Gago from ENAGAS presented a flagship proposal on Hydrogen corridors to cover Spain and Portugal, proposal that is supported by numerous entities that gathers a great consortium.


Regarding Valladolid, Henar Olmedo from CIDAUT stated that the City Council of Valladolid is working in a FCH roadmap, and, as signatory of the Covenant of Mayors, it has a Sustainable Energy and Savings Plan (SEAP). Any improvement of energy efficiency goes through the study and use of alternative energy to fossils such as renewable energy and can be hydrogen. The project to be implemented by the city council comes first in the awareness of citizens towards an unknown source of energy and reputed to be dangerous. Within the FCH technologies, the municipality has in mind the use of hydrogen in garbage trucks or buses.


Finally, as the closing of the event, the attendance of all the participants was appreciated and the next workshop was located in April, possibly in Santander.

CIDAUT participates in the National Climate Change Congress CNAC’18 organized by the UTAD


The National Congress on Climate Change CNAC’18 (  took place on 19, 20 and 21 February in the Aula Magna of the University of Trás-os-Montes e Alto Douro (UTAD) in Vila Real (Portugal).

This event arises from the need to discuss a current and pertinent problem, targeting students of higher and secondary education, researchers, teachers, technicians, auxiliaries and the public in general. There are many myths and taboos surrounding the dialogue on climate change and in this event it is intended to diagnose, elucidate and discuss the essential aspects of a problem that affects all of us.

The congress was divided into two parts: oral presentations and workshops. The oral presentations were extended throughout the first two days and they were focused on different aspects related to the impacts and challenges associated with climate change.


CIDAUT, invited by Residuos do Nordeste and UTAD, had the opportunity to make a presentation on sustainable transport and hydrogen applications in transport. An analysis of the current context of greenhouse emissions and other types of emissions (such as NOx and particles) associated with transport and the need to search for sustainable alternatives was carried out. Likewise, it was carried out a review of the main fuel cell and hydrogen technologies available and the applications of these technologies in land, maritime and air transport. An extensive review was made not only of the development projects but of the applications that are already on the market.

It was concluded that fuel cell and hydrogen technology is a mature technology with multiple demonstration projects of different vehicle typologies worldwide that are already a reality. There are vehicle typologies where mobility based on H2 is already competitive with batteries and a significant reduction in battery and battery costs is expected. Nevertheless, it is necessary to continue with performance improvements and reductions in weight and volume. Besides,the development of H2-based mobility requires a deployment infrastructure set.

CIDAUT continues to bet on the Circular Economy.

In the framework of the process of the Circular Economy Strategy and the Bioeconomy Plan, promoted by the Regional Government of Castilla y León through the Ministry of Development and Environment and the Ministry of Economy and Finance, respectively, a cycle of dissemination days and a meeting point for the development of projects and initiatives was launched in the end of 2017.


The last meeting took place on February 22, 2018: “Circular Economy and Bioeconomy: closing the cycle of organic matter: from bio-waste to bioproducts” in the PRAE building of Valladolid and was organized by the Institute for Business Competitiveness of Castilla y León (ICE). CIDAUT had the opportunity to attendas well as to exchange impressions and opinions on the use of organic matter in line with the principles of the Circular Economy.

The day brought together a group of papers aimed at highlighting the potential use of bio-waste and its organic matter as a raw material for the productive cycle or the natural cycle (nutrients, proteins, etc.), regarding the remains of agricultural or forestry operations, such as solid domestic or commercial waste and the remains of agro-food industries.

Among these uses fertilizers, compost or the production of biofuels and energy were highlighted as the most basic ones. The interest to obtain products with higher added value such as new foods, new materials or compounds for the pharmaceutical, cosmetic or other industries was also mentioned. The problem associated with the use of the organic fraction of the municipal solid waste from non-selective collection composted was highlighted. This problem is the one dealt with in the VALORCOMP project in which CIDAUT participates.
