The paper critically analyzed different interfacial enhancing methods used in thermoplastic composites. Although the absence of cross-linked polymer chains and chemical bonds on solidification enables the thermoplastics to be remelted, it creates weak interfacial adhesion between fibre reinforcements and the thermoplastic matrix. The weak fibre-matrix interface bonding reduces the efficiency with which the applied load can be transferred between these composite constituents, causing the composite to fail prematurely. Their need for high-temperature processing, poor compatibility with other polymer matrices, and relatively high viscosity render thermoplastics challenging when used to manufacture composite laminates. Therefore, various methods, including nanoparticles, changing the polarity of the fibre surface by plasma etching, chemical treatment with ozone, or an oxidative attack at the fibre surface, have been applied to improve the fibre/matrix bonding in thermoplastic composites. The fabrication steps followed in these techniques, their progress in research, and the associated toughening mechanisms are comprehensively discussed in this paper. The effect of different fibre-matrix interfacial enhancement methods on the mechanical properties of thermoplastic composites is also deliberated.
本文批判性地分析了热塑性复合材料中使用的不同界面增强方法。尽管固化时不存在交联聚合物链和化学键使得热塑性塑料能够重新熔融，但这会导致纤维增强材料与热塑性基体之间的界面粘结力较弱。纤维 - 基体界面结合力较弱会降低施加的载荷在这些复合材料组分之间传递的效率，导致复合材料过早失效。热塑性塑料需要高温加工、与其他聚合物基体的相容性差以及相对较高的粘度，这使得它们在用于制造复合层压板时具有挑战性。因此，已经应用了各种方法来改善热塑性复合材料中的纤维/基体粘结，包括使用纳米颗粒、通过等离子体蚀刻改变纤维表面的极性、用臭氧进行化学处理或对纤维表面进行氧化侵蚀。本文全面讨论了这些技术所遵循的制造步骤、它们在研究中的进展以及相关的增韧机制。还讨论了不同纤维 - 基体界面增强方法对热塑性复合材料力学性能的影响。
