摘要: Eight different chemicals were investigated as potential candidate coupling agents for phosphate glass fibre reinforced polylactic acid composites. Evidence of reaction the with and their effect on surface wettability degradation studied along principle role improving interface between reinforcement polymer matrix. It was found that, an optimal amount agent glass/polymer, interfacial shear strength improved by a factor 5. covalent bonding three investigated, namely: 3-aminopropyltriethoxysilane; etidronic hexamethylene diisocyanate. These also increased hydrophobicity surface. is expected that this would provide improvement in macroscopic properties full-scale composites fabricated from same materials which may help to retain these desired length time retarding breakdown fibre/matrix within
