The use of recycled thermoset composites in the thermoforming molds was investigated. To produce the recycled composite powder, cured composite products made of fiberglass were used, and the panels were ground into a powder using 36 grit sandpaper attached to a hand held die grinder. The powder was collected, and filtered through a strainer to achieve a consistent powder, and a sample of the powder was examined under an electron microscope, to determine the particle shape and size. The results show that the recycled fiberglass filler dough has good potential to be an excellent alternative for prototype thermoforming molds, and there was no variation between the ten parts produced from each mold.
