Improved Mechanical Property of Foam Glass Composites Toughened by Mullite Fiber

Abstract:

The mechanically improved foam glass composite toughened by mullite fiber was prepared by sintering technique, using waste sodium-calcium silicon flat glass powder as main raw materials. In this study, the preparation and properties of the samples were characterized by field-emission scanning electron microscopy (FESEM) and mechanical property test. The specific strength of the composite was defined for the first time, and applied into the investigation of mechanical property. The results show that with the increasing of the content of mullite fiber, the pore size of foam glass tends to be uniform and the obturator structure increased. But too much mullite fiber is added can produce a lot of microporous, flexural strength and density increased with the increase of mullite fiber content, when adding 10% (mass fraction) of mullite fiber, the maximum specific strength can reach 0.012m²/s².Good correlations between the microstructure (in particular the fiber distribution), the high specific strength and the high modulus of elasticity of mullite fiber.
