Summary: This paper investigates the impact compression behaviors of 3D angle-interlock woven composites (3DAWC) before and after thermo-oxidative ageing. The results show that the mechanical properties of the composites, including maximum stress and modulus, decrease with increasing ageing time. This degradation is caused by the degradation of epoxy resin and interface debonding. Finite element analysis reveals that ageing interfacial damage changes the crack propagation path during impact compression.

Summary: Impact damage distribution is crucial for designing composite structures with high-impact damage tolerances. In this study, the initiation, evolution, and distribution of impact damage in woven composites were investigated. The woven structure was found to greatly influence the damage propagation and the distribution of strain and stress. The high strength and straight arrangement of the weft yarn contributed to its high deformation resistance, large stress value, and wide stress distribution. On the other hand, the crimp of the warp yarn limited the stress distribution, leading to stress and damage concentration.

Summary: The mechanical behaviors of thermo-oxidative aged 3D braided composites are influenced by matrix degradation and crack evolution. The study investigates the degradation behaviors, crack propagations, and mechanical reduction mechanisms of three-dimensional five-directional (3D5d) braided composites under thermal oxygen coupling environment. The aging behaviors in a pure thermal environment were also analyzed for comparison. The results show that the presence of oxygen accelerates crack initiation and propagation, leading to a decrease in the mechanical properties of the composites.

Summary: Thermal stress concentration, caused by the mismatch of coefficients of thermal expansion, plays a significant role in the fatigue and failure of composites. We demonstrated the practicality of fiber Bragg grating sensors and high-resolution digital image correlation technique for in-situ characterization of thermal strain field evolution in 3D angle-interlocked woven composites. Our study found that the CTE mismatch leads to stress localization at the interface and exhibits a periodic distribution within the 3DAWC. The thermal stress in the resin reaches a maximum of 22 MPa around Tg, close to half of its yield stress.

Summary: The impact and flexural properties of 3D five-directional braided carbon/glass hybrid epoxy composites were investigated. Different arrangements of carbon fiber and glass fiber in the axial yarn were examined, and it was found that the C/G(2) composite had higher impact energy absorption capacity, while the C/G(1) composite showed higher impact stress. The flexural properties of the C/C-a composite were the best, while the C/G(3) composite exhibited the poorest performance before impact. This study provides guidance for the structural design of composites in specific applications.

Summary: In this study, a new method for preparing the three-way integrated braided preform was reported. The compressive behaviors of the three-way braided composite tubes were tested to reveal the effects of the braided structure. It was found that reducing branch length or increasing braiding layers can improve the compressive strength and initial stiffness. The main damage mechanisms observed were yarn breakage, yarn debonding, and kink band. The uniform braided structure paves the way for the formation of a seamless braided structure with high compressive strength among the three branch tubes.

Summary: This study investigates the effects of ageing cracks and loading directions on the mechanical behaviors of thermo-oxidative aged 3D braided composites. X-ray micro-computed tomography and digital image correlation technique are used to analyze ageing crack propagations, compressive responses, in-situ strain evolutions, full-field damage distributions, and crack evolution mechanisms. The results reveal ageing weakening behaviors, anisotropy effects, and structure correlations. Ageing cracks affect surface strain and damage distributions but not internal shear modes during out-of-plane (OP) loading. The synergy between ageing cracks and in-plane (IP) loading is greater than that with OP loading. This work provides important guidance for the structural optimization and durability design of 3D braided composites.
