Epoxy-glass fiber reinforced nanocomposites containing compatibilized ethylene propylene diene monomer (EPDM) rubber were processed for improved impact strength. Nanocomposites were reinforced with 1.0 wt% of nanoclay and 2.5–10.0 wt% of EPDM (both untreated and compatibilized). Compatibilization was done using two treatments: silane treatment and UV-assisted maleic anhydride grafting (MAH). SEM-EDS and FTIR confirmed EPDM treatment. SEM of fractured impact specimens was done to study effect of compatibilization on interfacial adhesion of nanocomposite constituents. XRD and TEM determined clay morphology in nanocomposites. EPDM concentration of 5.0 wt% resulted in maximum impact strength. For nanocomposites reinforced with silane treated EPDM, maximum improvement in impact strength was 68%, with a small drop in tensile properties. For MAH grafted EPDM, improvement in impact strength was 26%, but tensile properties recovered. Cavitation of rubber particles and improved interfacial adhesion of nanocomposite constituents were the main reasons for improved impact strength.

含有相容的乙丙二烯单体（EPDM）橡胶的环氧玻璃纤维增​​强纳米复合材料经加工可提高冲击强度。纳米复合材料用1.0 wt％的纳米粘土和2.5–10.0 wt％的EPDM（未经处理和相容）增强。相容性使用两种处理方法完成：硅烷处理和紫外线辅助的马来酸酐接枝（MAH）。SEM-EDS和FTIR证实了EPDM处理。进行了断裂冲击试样的SEM，以研究相容性对纳米复合材料界面粘合的影响。XRD和TEM确定了纳米复合材料中的粘土形态。EPDM浓度为5.0重量％导致最大的冲击强度。对于用硅烷处理的EPDM增强的纳米复合材料，冲击强度的最大改善为68％，而拉伸性能却有小幅下降。对于MAH接枝的EPDM，抗冲击强度提高了26％，但拉伸性能得以恢复。橡胶颗粒的空化和纳米复合材料组分的界面粘合性的改善是提高冲击强度的主要原因。
