THE DEVELOPMENT OF 3-D BRAID MULTIFUNCTION STRUCTURE COMPOSITES

Owing to the need of certain application a type of composite mataial is made not only to be a structural material but also to be provided with multiple functions,such as ablation resistance,impact resistance, thermal insulation etc.This type of composite material might be called "Multifunction Structure Composite Material" which should be designed by means of respective multilayers,so that different layers have different functions.The possibility to devel叩a_nd apply multifunction structure tomposits materials is provided by 3-D braid technologies,because of the integrated and special-shaped 3-D braid technologies to make different layers interbraided.The performance of 3-D braided composites and 3-D braid technoloaie.;manufacturinj multifunction structure composite materials are discribed in this paper.
