ANALYSIS OF HYBRID COMPOSITES OF 3-D WOVEN CARBON FIBRE AND PARTICULATES REINFORCED ULTRA-HIGH DENSITY POLYETHYLENE USING SCANNING ELECTRON MICROSCOPY
The composite materials based on renewable raw materials from agriculture and biomass is more used, because these products significantly compensate for the use of fossil fuels and reduce the greenhouse gas emissions in comparison with the petrol-based traditional materials. The composite from the 6cm of (3-D) woven mat Carbon Fibre and particulates: 0.075µm Metal Chips (Mild Steel), 0.075µm of Aluminium Silicate (Glass), 0.040µm Alumina (Ceramic) were the reinforcements while the smelted ultra-high density Polyethylene was the matrix. The percentage by weight of Polyethylene (matrix) was varied from 44wt% to 76wt% for optimization. The samples specimen of composites were produced for Mechanical property tests ; Tensile Strength of (10x15x100)mm3, Impact Strength of (10x10x100)mm3, Flexural Strength of (30x30x100)mm3, and Hardness Strength of (30x30)mm2. The experimental results showed that the highest Tensile Strength of 113MPa, Impact Strength of 2.855J, Flexural Strength of 122.517MPa and Hardness Strength of 67Hv were obtained. The Scanning Electron Microscopy was carried out to observe the fibre arrangements of 76wt%, 68wt%, 60wt%, 52wt% and 44wt% of the composite from the cut section. The result showed that 44wt% of resin in the composite has highest mechanical strength.
