The determination of chemical resistance to chemical reagents, fire retardant and flexural strength of commercial glass reinforced fiber / Ismarul Nizam Ismail

The glass-reinforced fïbre (GRP) is composites made by reinforcing a resin with glass fïbre. They have two particuiar interesting characteristics. They can be given a mechanical strength greater than any other plastics composites, comparable on a weight basis with some metats and they also can be mo...
