Development of carbon/epoxy structural components for a high performance vehicle

摘要: Development of the carbon/epoxy body panels and structural components Lamborghini Murcielago is discussed, while use aerospace grade technology materials justified for this particular application. The influence fiber architecture on strength a composite panel same fiber/resin system with focus two failure modes usually considered most critical in designing polymer composites, delamination flexural failure. Investigation covers four prepreg tapes fabrics, woven laminates over directional tape motivated. Resin impregnated carbon can offer great deal weight saving respect to their predecessors high performance sport cars, steel aluminum, yet, decades research metal science have produced manufacturing techniques that guarantee perfect surface finish, alloys withstand weathering agents during vehicle lifetime, very reliable joining methods, these relatively new require constant evaluation automotive applications ensure equal if not greater than metallic counterpart. Engineering solutions tooling operations order achieve class A certification are summarized. Design environmental aging as well accelerated degradation testing methods such ASTM D2247 Cleveland weatherometer G26 described. implementation hybrid adhesive bonding sole method tubular chassis reviewed.
