Chemical Resistance of Sisal/Glass Reinforced Unsaturated Polyester Hybrid Composites

The unsaturated polyester resin based sisal/glass hybrid composites were developed using the hand lay-up technique. Chemical resistance tests of these hybrid composites were performed in order to probe whether these composites can be used for making articles that are resistant to chemicals. The hybrid samples and the matrix have been tested for various acids, alkalis, and solvents. It is observed from the results that the developed hybrid composites are resistant to all the tested chemicals except carbon tetrachloride.
