PROPERTIES OF FIBER REINFORCED PLASTIC (FRP) USING GLASS FIBER AND FILLER RECYCLED FROM FRP WASTE

摘要

We have developed a method of decomposing unsaturated polyester (UP) into low molecular weight products without any corrosion of recyclates. The glass fiber and filler recovered from FRP waste by the method was tested as reinforcements for FRP. As a result, we found that the tensile and flexural strengths of the FRP using 100% recycled glass fiber were reduced to approximately 70% and 50 % respectively, compared with the original FPP, while no significant deterioration in the strengths was observed for the FRP containing 100% recycled filler. We recognized that our newly developed method could be available for recycling glass fiber and filler in FRP waste.
