纤维损伤对机织复合材料力学性能影响
Impacts of Fiber Damage on the Mechanical Properties of Woven Composites
摘要
Abstract
The study aimed to investigate the impacts of fiber damage on the mechanical properties of orthog-onal three-directional woven structural composites.By preparing carbon fiber orthogonal three-directional woven preforms with different damage rates and fabricating the composites by using the Resin Transfer Molding(RTM)process,a systematic evaluation of the mechanical properties such as tensile property,bending property and com-pressive strength was conducted.Combined with damage morphology analysis,the influence rule of fiber damage on the mechanical properties of the materials was revealed.The experimental results showed that as the carbon fi-ber damage rate increased,the tensile property of the composite decreased by 11.1%,the bending property by 24.7%,and the compressive property by 36.34%,with the damage rate having the most significant impact on the compressive property of the composite.The study provided a theoretical basis for optimizing the design and preparation process of carbon fiber orthogonal three-directional woven structural composites.关键词
