Abstract: This paper deals with the manufacture of carbon fiber reinforced glass-ceramic matrix composites.Three kinds of matrlcs are used machinable phlogopite glass-seramic,icpidolite glass-ceramic and LAS glassceramic.The composite sampics are prepared by powdersintering method in laboratory.This paper improves the normal manufacture process with introducing sol-gel method in composite forming process—the key part of the powdersintering process.According to the principle of sol-gel method,the paper investigate of sol-gel formula appropriated for composite manufacture,and also makes analysis and comparison on these three kinds of glass-ceramic composites with their monolithic metrics by means of physical and chemical test method.
