| Abstract | ||
| Tensile strength, compression strength, bending strength, and fracture toughness of phenol formaldehyde type novolac resin (PFN) reinforced with randomly-oriented different fibers as well as powders in terms of mechanical properties, which are subject to change in different additives volume fraction have been studied. Tensile strength, σT , results show that σT increases with the increasing volume fraction of additives. Failures display two mechanisms according to the kind of additives. Where, it can be observed, pullout mechanism with respect to fibers composites, and rupture mechanism with respect to powder fillers composites. Compression strength, σc , results show that σc increases with the increasing volume fraction of additives. Bending strength, σf, results show, that σf increases progressively by succession of volume fraction of fibers. Fracture toughness Gc , results show that Gc increased with increasing of volume fraction of additives. Failure takes place through two mechanisms, according to additives kind. Where, the failure takes place by pullout mechanism with respect to fibers composites, and by pining mechanism with respect to powder fillers composites. | ||
