SPECIFIC TENACITY DIAGRAMS OF FIBER-REINFORCED MATERIALS,

Abstract

Fiber-reinforced materials with a unidirectional continuous structure of the fiber consist, as a rule, of high-strength rigid fibers spaced parallelwise uniformly apart in a less rigid and less strong metal matrix and running in a direction parallel to the direction of application of the principal (tensile or compressive) load. In this connection, depending on the relationship between the density and strength properties of the fiber and the matrix, five standard diagrams of the dependence of specific tenacity of the fiber-reinforced material on the volumetric proportion of the fiber are plotted. Considering the difference in elasticity moduli and tensile strength between the fiber and the matrix, it may be stated that fracture of the composite (i.e. fiber-reinforced) material occurs during elastoplastic deformation of either the matrix alone or both the matrix and the fibers.
