The effects of heat treatment in the post-curing time and mechanical properties of both Glass Fibre/Lycal and Glass Fibre/Vinyl Ester composites have been systematically studied. This study is conducted to find an excellent composite material for float components. The composite material’s performance depends on the bonding between resin and fibre. The excellent bonding will occur upon the complete polymerization reaction of the resin, which represents the excellent polymer chain cross-link. These conditions are commonly called curing conditions. We did three different post-curing treatments for two different composites; they were conditioned at room temperature (approximately 25°C), 80°C, and 100°C, for 24 hrs, 4 hrs, and 4 hrs time respectively. The tensile properties have already been tested for both composites that refer to ASTM D3039. The value of Ultimate Tensile Strength (UTS) for both composites increased with the isothermal temperature from 25°C to 80°C, which is about 5.6% for Glass Fibre/Lycal composite, and the modulus of elasticity is increasing 21.12%. On the other side, the tensile test of Glass Fibre/Vinyl Ester composite increased significantly by 27.82%, but the modulus of elasticity decreased by 26.59% in 80°C heat treatment. Furthermore, compared with the 25°C post-curing treatment, the UTS value of Glass Fibre/lycal and Glass Fibre/Vinyl Ester composite with heat treatment at 100°C decreased to 5.2% and 15.26%, respectively.
