The feasibility of applying ARMT technology in long glass fiber reinforced PU foaming was verified by experiment. The ARMT made of ZnAl15 material can continuously bear the thermal shock at 217℃, the thermal conductivity is 15% higher than that of the mould made of resin, the rigidity is HV90 and the dimensional accuracy is about 2‰. The experiments indicate that the thermophysical and mechanical property of ARMT are better qualified than glass fiber reinforced plastics tooling for long glass fiber reinforced PU foam?ing; besides, its cost and cycle period are lower than traditional metal tooling.
