摘要

A novel thermoplastic skin concept, with co-consolidated stringers, is being brought to technology readiness level (TRLJ 6. This implies manufacturing and mechanical testing of full scale demonstrator products. The stringers are T-shaped and made of flat preforms that are butt jointed to each other and to the panel skin. An injection molded filler increases strength. The skin is fiber placed over the stringer preforms and the product is co-consolidated at melt temperature. Because of the butt-joints, manufacturing is relatively simple. The result is a tough thermoplastic product that can compete on weight and cost with state-of-the-art thermoset composite panels. Development and testing of the panel concept is being done in a step-by-step process. Consecutive building blocks are: coupons, three-stringer subcomponent panels and finally full scale skin panels. The main panel represents the mid-section of a business jet horizontal tail. The panel will be assembled into a 12 meter span torsion box and tested in the second half of 2011.
