Characterization Of Composites Made With In-House Prepregs At Different Curing Cycle

The main objective of this work is to improve the properties of 90 degrees carbon/epoxy laminates made with prepregs B-staged at different curing cycles. The effect of prepreg curing at 80 degrees C for 15 min and 100 degrees C for 5 min on the transverse modulus was analyzed for the epoxy system used. A series of tensile test were conducted to study the strength of material. Simultaneous Differential scanning calorimetry and Thermogravimetric analysis (SDT) is used to find the fiber volume fraction of the laminate. Void volume fraction was calculated by using ASTMD2734.
