摘要：

Interfacial sheer strength between acetylated fibres and various matrices was studied. The chemical modification of oil palm empty fruit bunch (EFB) and coconut fibre (coir) using non-catalysed acetic anhydride were investigated. Proof of acetylation of EFB and coir was indicated by the increase in weight percent gain, and was confirmed by Fourier transform infrared spectra. Pull-out tests were employed to study the compatibility of acetylated fibres with different commercial matrices such as "Epiglass" (epoxy), "West system': (epoxy), "Crystic" (unsaturated polyester), "Metset" (unsaturated polyester) and polystyrene. An increase in the interfacial shear strength between acetylated fibres and hydrophobic resins was noted. Modified fibres were shown to have a smoother surface compared with unmodified, which was believed to be a factor in improving the fibre-matrix adhesion. (C) 2001 Elsevier Science Ltd.
