On heat treatment, both hexacelsian and monoclinic celsian phases crystallize in BAS glass [23-25]. Also, hot pressing of barium aluminosilicate (BAS) glass or its composites reinforced with large diameter silicon carbide SCS-6 monofilaments or small diameter multifilament Nicalon or Hi-Nicalon fibers resulted in the crystallization of both hexacelsian andmonoclinic celsian phases [12]. On doping BAS with 5 wt.% monoclinic celsian seeds or 10 wt.% strontium aluminosilicate (SAS), only the celsian phase was formed in hot pressed... 

Composites Fiberglass is a composite in which glass fibers are used for reinforcement. Other ceramic fibers that are used as reinforcements are of carbon, silicon carbide, alumina, and aluminosilicate. Lightweight structures for aircraff and sfiff and light sporting equipment use carbon fibers.
