Gfrp Composite

Silicon Carbide/GFRP reinforced matrix composite and SiC matrix composite has been developed by using hand layup and resin casting methods respectively. The GFRP reinforced polymer composite is made by sandwiching two layers of GFRP in between the SiC material. The resin used for the preparation the samples are epoxy and polyester, for both Sic/GFRP composite and SiC composite. An Arcan fixture with butterfly specimen is used to measure the fracture occurring in various modes of the polymer composite. The objective of the proposed testing method is to determine the variation in the stress value depending on the resin material as well as the influence of GFRP in the strength of SiC polymer composite. Results from the tests are analyzed to show that the polyester resin is better for shear strength, in both Sic/GFRP reinforced and SiC composite material.

Static Mechanical Properties

Continuous silicon carbide fiber-reinforced silicon carbide ceramic matrix composites (SiCf/SiC) are promising as thermal structural materials. In this work, the microstructure and static mechanical properties of 3D-SiCf/SiC with PyC, SiC, and PyC/SiC and without an interface prepared via polymer infiltration and pyrolysis (PIP) were investigated systematically in this paper. The results show that the microstructure and static mechanical properties of SiCf/SiC with an interphase layer were superior to the composites without an interlayer, and the interface debondings are existing in the composite without an interphase, resulting in a weak interface bonding. When the interphase is introduced, the interfacial shear strength is improved, the crack can be deflected, and the fracture energy can be absorbed. Meanwhile, the shear strength of the composites with PyC and PyC/SiC interfaces was 118 MPa and 124 MPa, respectively, and showing little difference in bending properties. This indicates that the sublayer SiC of the PyC/SiC multilayer interface limits the binding state and the plastic deformation of PyC interphase, and it is helpful to improve the mechanical properties of SiCf/SiC.
