  • Fiber-reinforced plastic composite material for fastening pallets and process for producing the same
    Patent number: 5573843
    Abstract: Disclosed herein is a fiber-reinforced plastic composite material for fastening pallets to be used to transfer printed circuit boards for automatic soldering. The composite material is composed of a thermosetting resin, reinforcing long fibers, and a light-colored electrically conductive filler. The pallets are formed from the composite material by heating and pressing. The pallets have high electrical conductivity to prevent static build-up, a light color which permits coloring, and good mechanical properties.
