The Effect of Gamma-Radiation on the Physicomechanical Properties of Glass-Fibre-Reinforced Plastics Based on Thermoplastic Matrices

Abstract

An investigation was made of the modifying effects of polymer finishing agents and gamma-radiation on the elastic strength and dissipative relaxation properties of single-layer glass-fibre-reinforced plastics based on polyethylene and polyamine matrices. It was shown that this combination promotes reduced residual internal stresses at the phase boundary, more intense adhesion interaction between the surface of the reinforcing glass fibres and the thermoplastic polymer matrix, and accordingly strengthening of the polymer composite materials, especially in the case of a polyethylene matrix.
