摘要
Abstract
Factors affecting the thermal expansion coefficient of composite is of guiding significance for the design of thermal expansion coefficient of composite.The influence factors of thermal expansion coefficient of composite,such as fiber resin system,layer order,layer angle deviation and fiber volume content,are studied and the conclusions are given in this paper.The thermal expansion performance of the same matrix varies greatly,and the different matrix has a great influence on the thermal expansion coefficient of the same fiber.The outer layer of the 0° layer will help to reduce the axial thermal expansion coefficient,and will also contribute to the increase of the radial thermal expansion coefficient;the layer angle is from 30° to 60°,The deviation of thermal expansion coefficient caused by angle deviation is large.The axial thermal expansion coefficient of the composite tube and the volume content of the fiber showes a high nonlinear and non monotone,and the radial thermal expansion coefficient showes a monotonous decrease.关键词
