## Abstract The effect of absorbed water on the fracture surface energy of both glass and graphite fiber unidirectional epoxy composites has been studied. The fracture energy parallel to the fiber direction was measured by the double torsion technique. Water was absorbed at 70Β°C while the sample wa

Carbon fiber (CF) containing 1.4 and 2.1 mmol/g of -COOH and -OH groups, respectively, was functionalized by using an excess of tolylene-2,4-diisocyanate. The NCO-modified CF was submitted to a graft reaction with hydroxyl-terminated polybutadiene (HTPB). The HTPB-grafted carbon fiber was employed a
No simple correlation was found between the heats of wetting in methanol oi a number of carbons, prcp:ired from corn cobs and date pits under varying conditions, and the specitic surface arc.is of the carbons calculated from the adsorption isotherms of methanol vapour. Actually, the heat of wetting
