Fibre Loading

This study will focus on the usage of kenaf as a natural fibre in producing a composite materials consists of epoxy resin by resin transfer moulding (RTM). The variation amount of fiber loading and nonwoven fibre mat condition seems can give significant changes in properties of polymer composite in terms of mechanical aspects. Optimization of stitching density of nonwoven kenaf fibre mat manages to increase the mechanical behaviour. At higher degree of fibre loading, these enhancement properties are more apparent. Depending upon the direction of stitching process in producing nonwoven kenaf fiber mat, the composite obtained exhibit anisotropy behaviour in which the mechanical properties are vary upon the stitching direction of nonwoven mat.

Vartm Process

A study on the effect of the vacuum assisted resin transfer moulding (VARTM) manufacturing process on the mechanical properties of cotton/epoxy composite is presented in this investigation. Woven cotton was used as reinforcing material embedded in epoxy resin. The woven cotton was treated with sodium hydroxide for one hour at concentrations of 0% to 20%. The tensile test showed that the untreated material had the highest ultimate strength and Young’s modulus. Observation of the fracture surface by scan electronic microscopy (SEM) was compared to the hand lay-up process as well as the results of the tensile test. The comparison showed that the VARTM process presents better mechanical properties than the hand lay-up process due to the reduction in discontinuities observed by means of optical microscopy.

Transfer Moulding

Vinylester/epoxy (VE/EP) hybrid resins of interpenetrating network (IPN) structure were reinforced by needled flax fibre mat. The flax content of the composites was kept constant (20 wt%) whereas the VE/EP ratio varied (70/30, 50/50, and 30/70). The mechanical properties of the composites, produced by resin transfer moulding, were determined in tensile and flexural loading. The mechanical anisotropy detected was traced to the orientation of the flax fibres during carding. The higher was the VE content of the hybrid IPN resin the better the mechanical performance was.
