摘要

Flyash is an inexpensive material that can reduce the overall cost of the compostite if used as a filler for unsaturated polyester resin(RP).Flyash-filled unsatufated polyester resin(FPR)was cast into sheets.The tensile strength,flexural strength,and flexural modulus were determined.Calcium carbonate-filied polyester resin(CPR) and PR were also cast into sheets.The above-mentioned properties were determined and a comparison was made,The filler concentration was varied from 0 to 15 wt%.It was found that FPR was inferior to CPR and PR composites with respect to tensile and flexural strengths.But FPR was found to have a higher flexural modulus than those of CPR and PR.FPR with 10% flyash was found to have poor acid and solvent(benzene)resistances and good saltwater,alkali,weathering,and freeze-thaw resistances as seen from the mechanical properties.The possible ways of improving the strength of FPR are discussed.
