The effects of post curing process on the physical properties of Glass fiber /phenol –formaldehyde molded composites

The effect of post curing on two important physical properties of a Glass/Phenol- Formaldehyde (Novolac) composite is investigated. Samples are molded and postcured in different procedures. The Their Tg are measured using DMA test. The weight loss of sampled during post curing are determined as well. Result suggestthat the Post curing has a significant effect on TG of thermoset resin and increases it considerably. This ,in turn, will raise thermal resistance and dimensional stability of the composite
