Summary

Barium calcium aluminosilicate glass composites reinforced with about 4 weight percent of BN nanaotubes (BNNTs) were fabricated by hot pressing. Flexure strength and fracture toughness of the glass-BNNT composites were determined at ambient temperature. The strength of the composite was higher by as much as 90% and fracture toughness by as much as 35% than those of the unreinforced G18 glass. Pullout of the BNNTs was observed from fracture surfaces of the composite. Elastic modulus, density, and microhardness of the composite were lower than those of the unreinforced glass.
