Compaction and bending variability measurements of a novel geometry 3D woven layer to layer interlock composite textile around a 90° curve plate 3.2 mm radius

•The compaction behaviour of a novel 3D woven textile was measured and fitted with an empirical law•Bending variability measurements around a 90° curve plate geometry 3.2 mm radius was effectuated•Generated tables with hmin thickness on the 90° bend from the samples of the tested preform.•These data may be used for the manufacturing process of a generic node RTM process with the composite textile geometry.

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.
