以废电路板中的回收玻璃纤维粉体（RFGP）作为聚丙烯基复合材料的填充料，采用熔融共混方法制备了玻璃纤维粉体/聚丙烯复合材料（PPMC），并通过其力学性能测试和缺口冲击断面形貌观察，分别研究了 RFGP的表面改性、粒级及填充量对 PPMC 力学性能的影响。结果表明：经过γ-氨基丙基三乙氧基硅烷（KH-550）表面改性处理的 RFGP 可明显提高 PPMC 力学性能，其中粗粒级的 RFGP 对 PPMC 力学性能的提高幅度比细粒级的更显著，并随填充量的增加先升高后降低；当改性 RFGP 的粒级为180～450μm 及填充量为30%时，PPMC的弯曲模量、弯曲强度、拉升强度和冲击强度最大增幅分别为68.4%、31.2%、25.9%和41.4%。

Polypropylene matrix composites (PPMC) filled with recycled fiberglass powder (RFGP) from waste printed circuit boards (WPCB) were prepared by melt blending method in this research. The effects of surface modification,size fraction and content of the RFGP on the mechanical properties of the PPMC were investigated based on the results of mechanical properties and impact fracture surface morphologies of the PPMC. The results indicated that the mechanical properties of the PPMC can be significantly improved by adding the RFGP pretreated with KH-550 silane as a coupling reagent into polypropylene. And the PPMC with coarse fraction of the RFGP showed better mechanical properties than PPMC with fine fraction. Moreover,the increment of mechanical properties of the PPMC increased with the increase of RFGP content in the beginning and then decreased. When the modified RFGP content was 30% and the size fraction was 180—450 μm,the maximum increment of flexural modulus,flexural strength,tensile strength and impact strength of the PPMC was 68.4%, 31.2%,25.9% and 41.4%,respectively.
