ABSTRACT In this work, the surface of nano/micro-E-glass fibril (nGF) was modified with an amine silane coupling agent before applying as toughener for epoxy resin. The chemical structure and composition of silanized glass fibril (s-nGF) were also confirmed and compared with virgin nano/micro-glass fibrils. The curing reaction of epoxy samples with various s-nGF contents was performed at room temperature. Many characteristics of composite samples were also examined such as mechanical properties, fracture energy, thermal stability, and morphology. The experimental testing indicated that the s-nGF helps to improve the mechanical, thermal stability as well as the fracture energy of epoxy resin. The morphology observation also indicated that the s-nGF prevented the crack growth inside the epoxy matrix as the main reason of the enhancing fracture energy of epoxy resin with the presence of s-nGF.

氨基接枝纳米/微玻璃纤维作为环氧树脂新型增韧剂的硅烷偶联剂的制备和力学性能

摘要 在这项工作中，纳米/微 E 玻璃原纤维 (nGF) 的表面在用作环氧树脂的增韧剂之前用胺硅烷偶联剂进行了改性。硅烷化玻璃原纤维 (s-nGF) 的化学结构和组成也得到了证实，并与原始纳米/微玻璃原纤维进行了比较。具有不同 s-nGF 含量的环氧树脂样品的固化反应在室温下进行。还检查了复合材料样品的许多特性，例如机械性能、断裂能、热稳定性和形态。实验测试表明，s-nGF有助于提高环氧树脂的机械、热稳定性和断裂能。
