Optimization of Compression Molding Process in Laminated Woven Composites

The production parameters of compression molding have a significant effect on the mechanical properties of glass-reinforced composites. The effects of compression molding parameters such as curing time, curing temperature, and clamp pressure on the stress-strain relation of the woven composites are examined for the same volume fraction ratio (Vf 1/4 39%). The contribution of epoxy resin and curing agent mixing ratio is investigated as well. The optimum production parameters with desired mechanical properties are investigated. The stress-strain relation of laminated glass fabric-reinforced composites fabricated with different manufacturing parameters is evaluated under tensile loading. ANOVA is performed for investigating the significance of each variable.
