WASIS: Vibro-acoustic characterisation of the CFRP fuselage section

03/12/2015 by cidaut

As one of the last activities carried out within the WASIS FP7 Project, Cidaut performed the vibro-acoustic characterisation of two components, firstly one test panel and secondly the largest fuselage section (1m diameter prototype). In both cases the study covered low and high frequency ranges. The aim of this activity was to validate FEM/BEM models for low frequency range and SEA models for high frequency.

Advanced Composite Integrated Skin Panel Structural Testing – Results from Clean Sky ACID Project

03/11/2015 by cidaut

Stiffened panels are required in structures which can be obtained by different processes. They can be made by attaching stiffeners to a thin panel or by producing integrally stiffened panels. An innovating manufacturing process based on Liquid Resin Infusion (LRI) can be employed for obtaining integrally stiffened panels. It is based on moulding a dry NCF (Non Crimp Fabric) pre-form of Carbon fibre plies, which is bonded by a one-shot injection process to high stiffness, pre-cured pre-preg T-section stiffeners. This method presents benefits like lower costs in machining and fewer assembly operations.
