Abstract

There has been an increasing interest to improve the mechanical properties of the polymer based laminated composites. In this paper, glycerol is used as a solvent to improve the mechanical properties of glass/polyester laminated composites. Polyester resin is modified with 0, 5 and 10 wt% of glycerol. Glycerol and polyester resin are synthesized by hand stirrer. Hand layup method is used to manufacture the laminate made of bi-directional glass woven roving mat and modified polyester. The effect of glycerol is validated by subjecting all samples to the laminate mechanical testing. Results revealed improvement in the mechanical properties of the composites subjected to direct tension and compression test at ambient temperature (27oC). Impact toughness is evaluated under both ambient and low temperature (-10oC) conditions, as polyester resin is more brittle at low temperatures. Thermo gravimetric analysis results showed minor weight loss due to decrease in the cross-linking density of polyester with the addition of glycerol. It leads to the result that we can use this composite with glycerol as advanced material for wind turbine blade.
