Basic Characteristics of FRP with Scallop Shells as the Filler

The basic characteristics of FRP (Fiber-reinforced plastic) with scallop shells as the filler, including thickness and strength, were investigated through comparisons of non-mixture in limestone and based on limestone fillers in FRP. It was found that the mixture of resin and scallop shell was higher in the viscosity than the mixture of resin and limestone. The thickness of the scallop shell filler increased with a mixing rate higher than 30% but changed little for the non-mixture in limestone and calcium carbonate filler. The strength of the scallop shell filler decreased with a mixing rate higher than 30%, while that of non-mixture in limestone and limestone filler was constant. The results suggest that scallop shell fillers could achieve a strength and thickness comparable to that of non-mixture in limestone and limestone filler, and that a mixing rate lower than 30% of scallop shells can be utilized in FRP.
