Computer Simulation Study on The Relationship Between the Tensile Fracture Behavior of Aircraft Composites and The Fiber Strength Distribution

Composite materials have excellent characteristics such as high specific strength and high specific stiffness, but the whole life cost issue is still the core issue of composite materials applied to aircraft structures on a large scale. Although domestic and foreign researchers have conducted corresponding studies on the cost of each stage of aircraft composite material structure, the cost of each stage is still studied separately. This article first conducts tensile failure experiments on aircraft reinforced composite materials, and uses scanning electron microscope testing method technology to Observe the microstructure morphology of the transverse and longitudinal cross-sections of the composite material.
