摘要
Abstract
There are some limitations in the application of ordinary polypropylene(PP)/basalt fiber(BF)foamed compos-ites due to their poor foaming quality and toughness.In this study,maleic anhydride-grafted polyolefin elastomer(POE-g-MAH)was used as a compatibilizer to modify PP/BF composites,and the PP/BF foam composites were prepared at different contents of POE-g-MAH through a chemical foaming secondary mold opening process.The foaming quality and toughness of PP/BF composites controlled by POE-g-MAH were investigated by rheological,morphological,and mechanical measurements.The results indicated that the addition of POE-g-MAH improved the foam quality of the PP/BF foam composites.The composites exhibited optimal performance together with the best foam quality at a POE-g-MAH content of 6 wt%,and their foam cell size and density was 64.58 μm and 1.2×106 cells/cm3,respectively.Fur-thermore,the toughness of the PP/BF foamed composites was enhanced with an increase in the content of POE-g-MAH,demonstrating improved notch impact strength and fracture elongation.Specifically,the composite containing 6 wt%POE-g-MAH showed notch impact strength of 4.33 kJ/cm2,which increased by 84.25%compared to the com-posite without POE-g-MAH.关键词
