Application Of Textile Composite In Aerospace
Abstract:
Composite materials are made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct on a macroscopic level within the finished structure. A composite is made of a textile reinforcement structure and a matrix material. Textile reinforcement structure can be made of fibers arms or fabrics (woven, braided, knit non wovens) and are generally flexible. These structures are called texture performs. Textile preforms can be in various shapes and forms. Matrix materials can be thermoplastic or thermoset polymers, ceramic or metal. Textile composites can be flexible or rigid. Main characteristics of rigid textile composites are high stiffness, high strength and low density. Other characteristics include but are not limited to high temperature resistance, corrosion resistance, harness and conductivity depending on the product design for a specific application. Textile structural composites have higher strength - to weight ratio than metal composites. The application of traditional textile technology to organize high performance fibers for composite material applications has provided a route to combining highly tailored materials with enhanced process ability.
Many structural materials including metals have homogeneous and isotropic properties in general in isotropic materials, strength, stiffness, thermal and other properties are equal in all directions and at all locations. With the use of oriented fibers in bundles or layers, textile composites can be made anisotropic so that they exhibit different properties along different axes. Strength, stiffness, thermal and moisture expansion coefficients can vary by more than ten times in different directions.
