Abstract A distinctive region known as the fiber-matrix (F-M) interface/interphase (I/I) is formed between the matrix and fiber during composite manufacture. This region is assumed to be created in thermoset matrices by chemistry perturbations induced during the cure reaction. These perturbations occur at the un-sized or sized fiber surface, with the sized surface typically engineered to promote adhesion between matrix and fiber. Given the importance of this region to composite performance, potential chemistry perturbations that may arise are discussed, focusing on epoxy/amine reaction kinetics. These perturbations are linked to morphology changes that arise during fiber fracture. It is hoped that these ideas will facilitate a more complete understanding of the F-M I/I region and promote strategies for developing tougher composites.

DGEBA/胺反应动力学对玻璃纤维复合材料界面形成的潜在影响

摘要 在复合材料制造过程中，在基体和纤维之间形成了一个独特的区域，称为纤维-基体 (FM) 界面/界面 (I/I)。假定该区域是由固化反应期间引起的化学扰动在热固性基质中产生的。这些扰动发生在未施胶或施胶的纤维表面，施胶表面通常被设计为促进基质和纤维之间的粘合。鉴于该区域对复合材料性能的重要性，讨论了可能出现的潜在化学扰动，重点是环氧树脂/胺反应动力学。这些扰动与纤维断裂过程中出现的形态变化有关。希望这些想法将有助于更全面地了解 FM I/I 区域，并促进开发更坚固复合材料的策略。
