Abstract [en]

The aim of the current project has been to study the basic technologies needed to introduce local Point Cutting of fiber weaves (local PC) into composites manufacturing. An automated cutting machine is here used to locally increase the drapeability of standard weaves, hence easing tool loading and the automation of a production line. The two tested softwares cannot simulate draping using precut fiber weaves. Drapeability experiments can instead be used to select cutting pattern and cutting area. The used tool concept (one piece tool half, several tool parts, bag etc.) will affect the minimum size of the cutting area. Several cutting patterns have been tested including the innovative cross pattern, which works best. Micro-mechanical analysis and FE simulations show that the cured material properties can be predicted. A composite part has been successfully manufactured usinglocal PC technology.
