TAILORED FIBRE PLACEMENT OPTIMIZATION TOOL

摘要

European aircraft industry demands for reduced development and operating costs. Tailored Fibre Placement (TFP) is a promising technology which contributes to this aim by reducing structural weight at safe design; it exploits considerable reserves in structures made of Carbon Fibre Reinforcement Plastics (CFRP) by placing the carbon fibre rovings according principal stresses. This paper deals with selected results of 4 research projects in the field of TFP the Institute of Composite Structures and Adaptive Systems of DLR is working in. Within the first already finished project the tool TACO (Tailored Composite Design Code), which is a TFP design tool for lightweight aerospace structures, was developed. Three running follow-up projects deal with basic, research investigations, improvement of TACO and its industrial application as well as the automatic determination of the roving distributions.
