Abstract
The effects of glass fibre surface modification on the flow characteristics of unsaturated polyester (UPE) resin were investigated in
the resin-transfer moulding (RTM) process. g-Methacryloxypropyl trimethoxy silane (g-MPS) was used as a glass fibre surfacemodifier.
It was found that surface energy of glass fibre was decreased by g-MPS treatment by advancing contact-angle measurement. Unsteady
state permeability of glass fabric preforms was measured according to Darcy’s law. The apparent permeability of g-MPS-treated glass
fabric preforms was slightly lower than that of untreated fabric performs because of the macro/micro flow induced by capillary action.
The void contents and the flexural properties of the cured glass-fibre/UPE composites were estimated and morphological study of the
glass-fibre/UPE composites was also performed by SEM. When the fibre surface was treated with g-MPS, the void content and the
flexural properties of the glass-fibre/UPE composites were different in different regions of the mould cavity. # 2002 Elsevier Science
