Summary

This paper describes a materials engineering technique for measuring fiber-matrix interfacial shear strength in para-aramid epoxy composites, reporting a limiting shear strength of 105.2 MPa. It concerns structural composite materials testing and is not related to environmental microplastic pollution or associated health risks.

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.
