Structural composite parts production from textile preforms

In the proposed paper we discuss the resin transfer moulding of structural components from technical textile performs. A wing section prototype, based on a NACA profile, was produced by vacuum assisted RTM. The topics in this work will include practical issues such as perform production, mechanical properties of complex BD fabrics and questions raised by and related to the permeability of such fabrics. It will also touch the technology involved in producing these parts. Figure 1, presents a textile preform before and alter production of a wing composite part Numerical simulation of the process was performed in order to predict the mould filling and choose the best injection strategy.
