Composites based on carbon fibers and liquid crystalline epoxy resins, 2 -Dynamic-mechanical analysis and fracture toughness behavior

Full Paper: The dynamic-mechanical characterization and fracture resistance of composites, prepared by using a liquid crystalline epoxy resin and cont inuous carbon fibers, are presented and compared with conventional composit es. In the case of the LC matrix, a higher T-g was found; similarly, a supe rior fracture resistance, higher elastic modulus and higher T-g were found for the LC-based composites. These results allow to consider these material s as potential candidates for advanced composites.
