抄録

A process for recycling waste glass fiber reinforced plastic (GFRP) is proposed. In this process, porous glass fiber reinforced ceramics are produced by mixing clay with crushed waste GFRP and firing the mixture. The properties of tiles produced following this process and their applications are examined in this paper. First, several types of ceramic specimens (tiles) are produced using different firing temperatures and mixing ratios of crushed GFRP and clay. Next, the microstructure of each specimen is observed using scanning electron and optical microscopes. The density, bending strength and water absorption of the specimens are then examined in detail by comparison with those of porous tiles produced by mixing clay with plastic lacking glass fiber. The results show that the porous tiles containing glass fiber produced by our process possess high strength and water absorption. Finally, tiles are produced using actual waste GFRP as the raw material, and an example of the application of these tiles as a base material for vegetation is shown. Our results show that waste GFRP can be used effectively to produce porous ceramics.
