Epoxy-clay fiber reinforced plastics are employed in myriad applications. They, however, are brittle with less impact strength/related properties. There has been tremendous amount of research on processing of epoxy based glass fiber reinforced plastics (GFRPs) nanocomposites for obtaining good mechanical properties, especially impact strength. This review initially explains various clay morphologies in polymer-nanocomposites, and makes a care for compatibilization of reinforcing fillers. It discusses contribution of researchers with regard to: epoxy-layered silicate nanocomposites, epoxy-clay based GFRPs, polymer/elastomer modified composites, surface modification procedures for polymer/elastomer fillers, and multi-scale filler reinforced GFRPs. The key to improved impact strength of multi-scale filler reinforced epoxy GFRPs lies in good compatibility of polymeric/elastomeric fillers with other constituents. Various techniques for this purpose have been discussed. Most recent developments where researchers have processed epoxy GFRPs containing clay as nano-filler and compatibilized thermoplastic-fibers/elastomeric-particles as micro-filler providing improved impact strength/tensile properties have been described. Finally, scope of future research has been presented.

多尺度填料增强环氧纳米复合材料在改善冲击强度方面的进展:综述

环氧粘土纤维增强塑料用于多种应用中。但是,它们是脆性的,具有较小的冲击强度/相关性能。为了获得良好的机械性能,特别是冲击强度,对基于环氧的玻璃纤维增​​强塑料(GFRP)纳米复合材料的加工进行了大量的研究。这篇综述首先解释了聚合物纳米复合材料中的各种粘土形态,并对增强填料的相容性给予了关注。它讨论了有关以下方面的研究人员的贡献:环氧层状硅酸盐纳米复合材料,基于环氧粘土的GFRP,聚合物/弹性体改性的复合材料,聚合物/弹性体填料的表面改性程序以及多级填料增强的GFRP。提高多级填料增强的环氧GFRP冲击强度的关键在于聚合物/弹性填料与其他组分的良好相容性。已经讨论了用于该目的的各种技术。描述了研究人员处理含有粘土的环氧玻璃纤维增​​强塑料(GFRP)作为纳米填料,增容的热塑性纤维/弹性体颗粒作为微填料的最新进展,可改善冲击强度/拉伸性能。最后,提出了未来的研究范围。描述了研究人员处理含有粘土的环氧玻璃纤维增​​强塑料(GFRP)作为纳米填料,增容的热塑性纤维/弹性体颗粒作为微填料的最新进展,可改善冲击强度/拉伸性能。最后,提出了未来的研究范围。描述了研究人员处理含有粘土作为纳米填料的增容环氧玻璃纤维增​​强塑料和作为微填料的相容热塑性纤维/弹性体颗粒(提供改善的冲击强度/拉伸性能)的最新进展。最后,提出了未来的研究范围。
