Compaction and bending variability measurements of a novel geometry 3Dwoven layer to layer interlock composite textile around a 90° curve plate3.2 mm radius

The aim of this investigation is to measure compaction and bending variability of a novel composite 3D woven textile layer-to-layer interlock around a 90° curve plate geometry. To that, end with the use of an empirical power law the compaction behaviour of the novel weave geometry textile fitted. This way it is possible to evaluate the max shear stress at 90° during bending. The preform thickness variation along the bending was measured with the use of a Coordinate Measurement Machine. The overall methodology and data variability measurements are useful for the manufacturing process of composites at macro-scale level as predictive data in Resin Transfer Moulding flow analysis for a complex composite node with 90° bend moulder geometry.
