“…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. Their results showed that the transverse and longitudinal compressive strength of composites with dual matrix are bigger than that with single matrix.…”

“…In Figure 5 a, the matrix of the C/C composite is mainly composed of smooth laminar (SL) pyrocarbon, which shows numerous ring cracks between the fiber and the matrix [ 32 ]. By comparison, due to the presence of graphene, the matrix of the C/G/C composite is mainly composed of rough laminar (RL) pyrocarbon in Figure 5 b [ 33 , 34 ]. The large surface energy of graphene may induce the formation of a highly textured pyrocarbon during chemical vapor infiltration (CVI).…”

In this work, we developed an interface modified by graphene to simultaneously improve the mechanical and frictional properties of carbon/graphene/carbon (C/G/C) composite. Results indicated that the C/G/C composite exhibits remarkably improved interfacial bonding mode, static and dynamic mechanical performance, thermal conductivity, and frictional properties in comparison with those of the C/C composite. The weight contents of carbon fibers, graphene and pyrolytic carbon are 31.6, 0.3 and 68.1 wt %, respectively. The matrix of the C/G/C composite was mainly composed of rough laminar (RL) pyrocarbon. The average hardness by nanoindentation of the C/G/C and C/C composite matrices were 0.473 and 0.751 GPa, respectively. The flexural strength (three point bending), interlaminar shear strength (ILSS), interfacial debonding strength (IDS), internal friction and storage modulus of the C/C composite were 106, 10.3, 7.6, 0.038 and 12.7 GPa, respectively. Those properties of the C/G/C composite increased by 76.4%, 44.6%, 168.4% and 22.8%, respectively, and their internal friction decreased by 42.1% in comparison with those of the C/C composite. Owing to the lower hardness of the matrix, improved fiber/matrix interface bonding strength, and self-lubricating properties of graphene, a complete friction film was easily formed on the friction surface of the modified composite. Compared with the C/C composite, the C/G/C composite exhibited stable friction coefficients and lower wear losses at simulating air-plane normal landing (NL) and rejected take-off (RTO). The method appears to be a competitive approach to improve the mechanical and frictional properties of C/C composites simultaneously.

“…Therefore, in the tensile testing, the composites were oriented in a way where the fibres are parallel to the direction of the applied load. On the other hand, since there is less work on the compressive and hardness of such composites [21][22][23], compressive and hardness tests were performed in two directions with respect to the applied load. In the horizontal direction, the applied load is perpendicular to the fibre mats, and, for the parallel, the fibre mats are parallel to the applied load.…”

Recently, recycled thermoplastic polymers become an alternative resource for manufacturing industrial products. However, they have low mechanical properties compared to the thermosets. In this paper, an attempt has been made to enhance the mechanical properties of recycled high density polyethylene (HDPE) with chopped strand mat (CSM) glass fibres as a synthetic reinforcement and with short oil palm fibres as a biodegradable (natural) reinforcement. The effects of volume fraction of both synthetic and natural fibres on tensile, compression, hardness, and flexural properties of the HDPE were investigated. The failure mechanism of the composite was studied with the aid of optical microscopy. Tensile properties of the HDPE composites are greatly affected by the weight fraction of both the synthetic and the natural fibres. The higher strength of the composites was exhibited when at higher weight fraction of both natural and syntactic fibres which was about 50 MPa. Date palm fibre showed good interfacial adhesion to the HDPE despite the untreated condition used. On the other hand, treatment of the fibres is recommended for higher tensile performance of the composites.
