Abstract : Maxdem has developed a novel family of thermoplastic resins, designated Poly-X(TM), which demonstrate exceptional strength and modulus. PolyX(TM) is based on a new type of rigid-rod polymer structure which combines good mechanical properties with facile processibility. Therefore, parts can be molded from Poly-X(TM) resins by a variety of common molding techniques and are projected to possess ultra-high mechanical strength and stiffness. Composites fabricated with Poly-X(TM) resins are expected to have unprecedented compressive strengths due to the high modulus of the Poly-X(TM) matrix resin. During the proposed Phase I work, initial experiments will be performed to demonstrate suitable fibermatrix adhesion for composite applications and that high strength parts can be molded. Work has begun to prepare the quantities of polymer required to perform these tasks and to fabricate test samples to allow evaluation of the fiber-resin interfacial properties. During the Phase II work, new composites will be fabricated which are projected to possess significantly enhanced compressive strength compared to the current state-of-the-art.
