Investigation of induced thermo-mechanical response and cure kinetics during processing of carbon fiber reinforced plastics.
… During laminate manufacture, reinforcing fibers are impregnated with resin and subjected to catalytic conditions. Under these conditions, the resin transforms from liquid to solid as polymer chains form a crosslinked network. During this process, the phenomenological events of gelation and …
