Abstract

The mechanical performance of glass matrix composites reinforced with large diameter (140 µm) monofilaments has been investigated. Strong interfacial adhesion between uncoated boron monofilaments and the borosilicate glass matrix resulted in composites exhibiting low failure strain and brittle fracture. The use of coated monofilaments improved composite performance considerably by reducing fiber-matrix interfacial adhesion. Auger analysis of the interface indicated that a carbon-rich layer had formed between the monofilament coating and the matrix during composite fabrication
