Puncture impact tests of injection molded glass reinforced polypropylene with and without elastomer were conducted at temperatures of 23℃ and -30℃ to compare and quantify the effects of elastomer addition and residual glass fiber length on material impact energy absorption. The addition of elastomer resulted in a significant increase in the impact energy absorption at 23℃, but had little effect at -30℃. The residual fiber length dramatically influenced the impact energy absorption for the glass fiber reinforced polypropylene without elastomer addition. At -30℃, glass fiber reinforced polypropylene without elastomer and with residual glass fiber lengths of greater than 3 mm achieves equivalent impact energy absorption as the elastomer modified glass fiber reinforced polypropylene with similar glass fiber length.
