“…3,4 Fibre reinforced-resin matrix composite components are generally manufactured to its near net shape using various stages of processes such as filament winding, vacuum bagging and autoclave molding. 5,6 However, conventional machining processes such as turning, 7 drilling 8 and milling 9 are inevitable to obtain the desired dimensional and surface requirements. Conversely, several difficulties are encountered during these machining processes; which include high tool wear, fraying of composites, formation of burs and fibre-matrix interface damages.…”

Although surface grinding is reported to be capable of precision material removal in carbon fibre reinforced epoxy polymer composites (CFRPs), it is highly limited by deprived cutting temperature dissipation, tool wear and sensitivity to undesired cutting defects. Continuous engagement of abrasive grains and successive accumulation of heat at cutting interface in conventional surface grinding results in severe surface damages. Though the controlled application of cutting fluids exhibited improved surface integrity, entrapment of fluid droplets into the defective zones/cracks of fibre, matrix and its interfaces are shown to be stimulating further defect propagation. Present paper investigates the feasibility of improving cutting fluid application in CFRP grinding, establishing a minimum surface defect condition through eccentric sleeve grinding (ESG). The reduction of post-grinding surface defects through an intermittent-progressive cutting scheme in ESG is demonstrated and the efficacy of cutting fluids in such a grinding scheme is illustrated through the comparison of grinding forces and surface characteristics.

“…In addition, because of the introduction of epoxy groups, no water is generated during the curing process of the modified resin, and the wettability with fiber materials (glass fiber, CF) is also enhanced. 13 Park et al 14 prepared CF/PR composites, and the results showed that after proper heat treatment, the interface properties of CF chips were significantly improved, thereby making the interface adhesion between recycled CF and PR much improved. Yuan et al 15 studied the effect of CF surface modification pre-treatment on the properties of reinforced PR-based composites.…”

Epoxy resin and carbon fiber were used as the reinforcement to modify phenolic resin. Phenolic epoxy resin was prepared by physical blending, and carbon fiber was introduced into the resin matrix, and meanwhile the curing agent was added. The flame retardancy and thermal stability of the samples were evaluated, and the mechanical performance of the samples was characterized to investigate the overall performance. The flame retardancy of phenolic epoxy resin decreased slightly with epoxy resin of 5 wt%. The oxygen index was decreased by 6.3%, the ignition time was shortened by 66 s, and the peak heat release rate was increased by 8.9%. The tensile strength and elastic modulus were increased by 46% and 26.1%, respectively. The flame retardant and mechanical properties of phenolic epoxy resin were improved the most with short carbon fiber of 0.5 wt%. The oxygen index was increased by 4.6%, the ignition time was delayed by 35 s, the peak heat release rate was reduced by 18.9%, the carbon residue rate at 800℃ was increased by 60.4%, the apparent activation energy was increased by 11.3%, and the tensile strength and elastic modulus were improved by 90.4% and 87.9%, respectively.
