A technique for determining the shear strength at the fiber–matrix interface was developed. The experiments used the copolymer of para-aramid fiber Rusar C (Termotex SPC) and a polymer composite based on KDA epoxide resin. The limiting strength was found to be 105.2 MPa. The dependence of the strength of single filaments on the clamping length, thread strength, and strength of a microplastic fabricated from this thread were used as the input information.
