Abstract

The article presents the results of investigation of the following properties of fiber: geometric cross-sectional characteristics, crystal structure, mass fraction of the dressing, linear density and fiber density, geometric cross-sectional characteristics of microplastics, tensile strength, modulus of elasticity and elongation at break of the microplastics. For carbon fiber reinforced plastic (CFRP) the following properties were determined: ultimate strength and modulus of elasticity under tension and bending, compressive strength, in-plane and interlaminar shear strength, curved beam strength, transversal strength, residual compressive strength after impact, specific interlaminar fracture toughness under Mode I and Mode II loading conditions. At the same time the microstructures of carbon fiber plastics were studied.
