摘要：

The microcellular foaming PP/GF composites was made under the condition of twice-open mold by using chemical foaming injection method, according to glass fiber reinforced mechanism, the effect rule of GF on mechanics properties was studied in microcellular foam PP composites. The results showed that tensile and impact strength of Micro-foam PP/GF composites by one-step method were higher than that of micro-foam PP/GF composites by two-step method, when the content of GF is 30%, the tensile and impact strength of micro-foam PP/GF composites by one-step method can reach 55.72MPa and 7.5kJ/m(2) respectively, one-step method can get higher strength and higher toughness micro-foam PP/GF composites.
