The Polymeric Heterogemeous Matrix for Carbon and Glass Reinforced Plastic

Abstract

This article presents the results of deformation-strength properties measurement and microstructural analysis of heterogeneous polymer matrix consisting of thermoset and thermoplastic polymers. Thermosetting material is a diamino-diphenil sulfon-cured epoxy oligomer. Polysulfone was used as thermoplastic material. Two different technological processes were used to obtain heterogeneous polymer matrix: the material was mixed in the block, or layered material was produced in which a layer of thermoplastic material alternated with a layer of epoxy oligomer.

Composite Materials Monitoring by Fiber Optic Sensors

“…A composite material may be defined as a combination of several materials with quite different mechanical, thermal and electrical properties. The materials combination forms a matrix of the composite material that provides material solidity and correct mutual arrangement of reinforcing filaments [9]. Delamination and damage of the matrix are the most common and dangerous cause of the composite materials injuries which lead to degradation of mechanical properties and finally result in the failure of the composite material [10,11].…”
