Glass-fiber reinforced glass (GRG) composites are a new low-cost, efficient use of composite materials. In this paper, according to a reasonable fiber/matrix matching principle, the sandwich structure method was used to fabric GRG composites by means of high modulus, high strength, thermal stability and the appropriate coefficient of thermal expansion characteristics of glass fibers and a good overall performance as matrix. And glass fiber reinforced glass composite of the performance of research and analys...
