“…For example, Li et al [4] showed that the C/C composite produced from chopped fibers/resin carbon had the low tensile strength due to its poor microstructure and the strong interfacial bonding between resin carbon and carbon fibers. Zhang et al [5] conducted thorough research on compressive fracture behavior of 3D needle-punched C/C composites.…”

“…They show the best high temperature mechanical properties in an inert environment which can withstand temperatures up to 2000℃. Moreover, their high strength and toughness can be maintained with the increase of temperature, even are higher than that at room temperature [1,2]. Just because of these superior thermal and mechanical properties which persist at high temperatures, C/C composites are widely used in nose cone and wing leading edge of hypersonic aircraft and hot-end components of high thrust loading aeroengine [3,4].…”

Bending cyclic fatigue tests of 2D laminated C/C composites were conducted under load control at a sinusoidal frequency of 10 Hz. And three-point bending tests of fatigued specimens with various cycles were conducted at room temperature to evaluate the effects of cyclic load on mechanical properties. 2D C/C specimens were prepared by an isothermal chemical vapor deposition (CVD) process. The mechanical properties of composites were improved after cyclic loading at most the flexural strength by about 46% and the modulus 38%. The results show that the flexural properties of C/C composites were enhanced with the increase in fatigue cycles. It is suggested that the weakened interface between matrix and fibers by cyclic load play important roles in enhancing the property of C/C composites.

Carbon/carbon (C/C) composites as high temperature structural materials have been widely used in aeronautics and astronautics because of their remarkable mechanical, thermophysical, and tribological properties. For the deep investigation of carbon deposition mechanism, newly developed approaches of fast densification of C/C composites have been indicated, such as thermal gradient chemical vapor infiltration (TCVI), pressure gradient chemical vapor infiltration (PCVI), electrified CVI (ECVI), and chemical liquid‐vaporized infiltration (CLVI). Multilayer coating system provides a new way for the long‐term antioxidation of C/C composites. Carbon nanotubes and nanofibers, forming the bridge between carbon fibers of micrometer size, could also further enhance the mechanical properties of composite materials. Bonded repair of C/C composite structure is used to extend the life of wear or underdesigned components and joins different components at a reasonable cost. All these studies promote the research and development of advanced C/C composites.
