Abstract

The physical–mechanical properties of mineral fibers manufactured from scoria obtained from two deposits in Armenia are studied. It is shown that the slag fibers can be used as an alternative to the widely used glass fibers. Their elastic modulus is identical to that of S-composition glass fibers and their strength is close to that of E-composition glass fibers. The elastic-strength properties of the composites exceed the corresponding indices of materials based on basaltic and andesite-dacite fibers.

Abstract

The properties of mineral fibers consisting of andesite-dacite, which is an effusive volcanic rock, are studied. The elastic-strength characteristics of elementary fibers, filaments, and also microplastics and plates consisting of unidirectional composites fabricated from filaments and EDT-10 epoxy binder are investigated. It is shown that the characteristics of the fibers are quite high and close to the properties of non-alkaline glass and basaltic fibers.
