Research progress in preform weaving technology and material mechanical properties of three-dimensional special-shaped textile composites

Abstract

In recent years, three-dimensional textile composites have been widely used in major national defense projects due to their excellent overall performance, rich structure, and net shape. Among them, the theoretical research of three-dimensional special-shaped textile composite materials is still far behind the application. Starting from the application of three-dimensional special-shaped textile composite material components, according to the typical characteristics of various components, the application status of three-dimensional special-shaped textile structural parts is summarized, and the main weaving process and weaving equipment development status of the three-dimensional special-shaped textile composite material preform were summarized. the research progress of the mechanical properties, meso-structure modeling and numerical simulation of 3D special-shaped textile composite materials from different levels at home and abroad were analyzed, and the key problems faced by the research of 3D special-shaped textile composite materials were put forward, aiming to provide support for the future applications of three-dimensional special-shaped textile composite materials.
