A composite plate consisting of ultrahigh-molecular-weight polyethylene (UHMwPE) was placed in front of aluminum alloy plates to reduce ejecta with the ultimate goal of reducing space debris. The temperature effects on crater size and ejecta generated from aluminum alloy plates with UHMwPE fiber composite were examined. When a UHMwPE fiber composite plate with a thickness of 1.0 mm was placed in front of an aluminum alloy 6061-T6 thick plate, the crater diameters and depths on the aluminum alloy plate clearly decreased, and the number of ejecta from the aluminum alloy plate with UHMwPE fiber composite clearly decreased. In addition, UHMwPE fiber composites with a thickness of 1.0 mm continuously reduced ejecta, even at high temperatures.
