Problems solved by technology

However, the ultimate strength of particular constituent materials can limit the achievement of the highest performance
For example, tests have shown that fiber performance is limited by the low critical distortion capability of the matrix of the thermoset resin used

Abstract

A thin felt-stabilized composite material may comprise: at least one reinforcement layer formed of a reinforcement material; a plurality of interlayers alternately arranged between and bonded to the reinforcement layer, each The interlayers are each formed of an interlayer material having a first twist deformability; and a matrix material injected into the reinforcing layer and the interlayer, the matrix material having a second twist deformability, wherein the first twist deformability is greater than The second twist deformability is to increase the tensile strength of the composite material.

Description

technical field [0001] The present disclosure relates generally to cured composite materials, and more particularly to thin felt-stabilized fabrics of cured composite materials utilizing interlayers in conjunction with reinforcing layers to obtain increased tensile strength. Background technique [0002] High-performance composites built from alternating layers of unidirectional reinforcing fibers offer the combined benefits of high strength and light weight. Composites are therefore used in aerospace and other industries where such performance requirements are critical. In general, composites are prepared by laying up several alternating layers with adjacent layers having unidirectional fibers extending at different angles. The cumulative net effect of several layers of such unidirectional fabrics is to provide a composite material possessing superior strength (either quasi-isotropic, or in one or more specific directions). Such composites can be produced as prepregs or p...
