Study on the effect of aluminium addition on the physical properties of unsaturated polyester/ jute composites

Jute fibre along with Al particle reinforced unsaturated polyester composites having different filler (both Jute and Al were in equal wt.%) loading viz. 2, 5, 10 and 15 wt.% were fabricated by compression molding technique. Structural investigation is done through SEM. The physical testing like density measurement, void % measurement and gel point calculation has been done and optimum result obtain for UP/Jute/Al composites at the filler content of 10 wt.%. At 10 wt.% of filler content the UP/Jute/Al composites contain lower void content and cure at a controllable manner. Due to this feature of the UP/Jute/Al composites, these composites may be shown good mechanical property.
