Abstract

The current study investigates the fabrication and mechanical strength of five-layer carbon-carbon composite. The strong five-layer carbon-carbon composite material with high strength and modulus is made of a raw material called precursors. The polyacrylonitrile (PAN) method is used in the fabrication of carbon fiber. The characteristics of the resulting carbon material depend on the composition and structure of the precursor. A sheet of 50 x 40 cm five-layer carbon-carbon composite material has been made out of this PAN method. Tests like flexural, tensile, compression, and impact were performed on the fabricated samples to evaluate the mechanical strength of the carbon-carbon composite material. A total of 14 samples were made according to ASTM standards. The material withstood a maximum tensile strength of 492.12 MPa and a flexural strength of 578.13 MPa. The maximum impact energy is recorded as 6.1 joules. Graphs are plotted between the load and deflection to illustrate the mechanical behaviour of the composite material. The material exhibited linearity throughout the test among all the samples. The process involves the creation of two-ply plain weave laminates using T300-1k carbon fiber combined with Hexcel HexPly 913 epoxy resin, resulting in a fiber volume fraction of 0.62. The examination of different idealized tow cross-sectional shapes and weave profiles, including a beam model, a solid material model with a comparable cross section of rectangular shape, and two models with sinusoidal tow profiles.
