The main output of the project was demonstration of composite parts which replace existing aluminum parts, the composite parts- door linkage and door rod achieved the project targets - weight reduction in comparison to the metal parts and ow cost for serial production, as result the parts affect directly on aircraft fuel consumption, aircraft weight and environmental pollution.
Work package Summary of main results IAI and CirComp
State of art analysis-Both companies, IAI and CirComp were involved in selection of main preferred technology stream using full break down description of weight and cost analysis, the using of automated manufacture process were also considered at each part configuration.
Concept -The conceptual approach was to find the best technology which will fit for low serial cost product as possible and decrease weight.
Preliminary design and analysis -CIRCOMP company and IAI were involved in design of seven different demonstrators which comply to less weight and serial cost, the technology parameter of each demonstrator was examined to show the best selection
Detail design and analysis
Door linkage and door rod were passed the design phase successfully and implemented to the manufacture phase, both parts were analyzed and shown less weight and less serial cost .
Production
IAI Door linkage manufacture injection has demonstrate during the RTM process ( put the ready preform inside molding and injected), CirComp door rod technology evaluation during manufacture phase shows that beside the filament winding process the AFP process could be suitable for the door rod manufacturing, mechanical properties, fiber distribution, consolidation etc. was compared between a CF-PEEK tube and a CF-Epoxy tube with the same dimensions.
Qualification tests-CirComp was finish the door rod testing at TRL 5 level with coordination with Liebherr.
IAI Door linkage will be tested by IAI in the coming months to a level of TRL5.
The target of the project was to achieve TRL6 while only TRL5 was achieved
SOF Completed
The project, in agreement with the topic manager, decided to prioritise the design activities and finely the SOF activities could not be performed.
overview of the results and their exploitation and dissemination
Reduction of composite production cost of about 20% compared to state-of-the-art composite strut and reduction of composite production cost of about 15% compared to composite door linkage.
Reduction of structural weight after the prototype manufacture of about 38.5% with respect to metallic reference weight on the door linkage and 52% with respect to the door rod (without rod ends).
Lowering the costs using automated manufacturing process-less labor hand
Lowering weight using advance matrix and carbon fiber -better competitions less pollution
