摘要

The focus on process improvements in high performance lightweight structures is mainly locatedrnon thermoset material. Resin transfer moulding processes have been developed to decrease costrnfor high performance structures in competition to prepreg material. However, thermoplasticrnmaterials, such as CF/PEEK, CF/PEKK or CF/PPS, offer interesting opportunities despite thernhigher material cost compared to thermosets.rnThis paper shows two examples using continuous fibre reinforced thermoplastic material and thernjoining processes among themselves as well as to titanium in a hybrid structure design. Costrnreduction is demonstrated using vacuum consolidation, special moulds and several weldingrntechniques.rnThe first example is a rudder from the vertical tail plane of a military aircraft. Severalrnmanufacturing steps including forming or shaping with flat plates, positioning stringers duringrnvacuum consolidation, welding of ribs and welding of the central spar are shown. A costrnstatement is given analysing the overall manufacturing process.rnThe second example shows the design study of a hybrid fan blade of an aero engine, made fromrntitanium and CFRP part joined along an extended surface. The fan blade is a newly developedrnhigh performance blade to save weight and to increase the pressure ratio per compressor stage, sornthat one complete compressor stage is obsolete. A newly developed finite element model forrncombining titanium and CFRP is introduced and the special aspects of draping and consolidationrnin low cost moulds are shown.rnFuture prospects are the integration of additional functions into the structure like lightningrnprotection, bird impact improvement and combination of short fibre and continuous fibre material.rnHeated press processes during consolidating or welding are reducing cycle times. Some examplesrnsuch as the man hole access cover, door frame or suspension arm in automotive application arernshown with feasible process cycles.
