Hygrothermal Degradation Studies on E-Glass Woven Rovings-Epoxy Composite

In the present work, the property degradation of the selected material (i.e. E-glass & epoxy resin composite) manufactured by compression molding was investigated as a function of temperature after direct wetting in saline medium for varying periods. For the preparation of composite specimen, ARADUR HY951 used as hardener with ARALDITE LY556. From the experiment, moisture gain trends for different temperatures which vary with time. In that, hot setting laminate having good strength when compared to cold setting laminate. It is hoped that generation of such data will help in determining the active service life of products, beyond which, they need to be discarded to prevent catastrophic failures.
