Enabling Technologies for Economical Manufacturing of Composites
Abstract
Two separate contributions to the state-of-the-art in on-line (out- of-autoclave) consolidation of thermoplastic matrix composites have been developed under this program. First, an induction consolidation sensor has been developed which appears capable of detecting differences in consolidation state without physical contact. The consolidation defects detected are in the category of "kissing unbonds" (KUB's). Second, in collaboration with Lockheed and the Air Force Phillips Lab, in-situ consolidation of thermoplastic composites by means of direct electrical heating has been demonstrated at realistically high winding speeds. A version of the "top-of-component electrode" which is capable of off-axis laydown and fabrication of crossplied tubular laminates has been constructed and tested. Reasonably good consolidation has been obtained thus far, though quality assessment is still in progress. Composite laminates, Kissing unbonds, Thermoplastic composites.
