Compaction Behavior of 0°/90° Non-crimp Fabrics

Abstract

Based on the beam theory, a compaction model of 0°/90°non-crimp fabrics was developed to investigate the relationship between the thickness and compression load. A layer of 0°/90°non-crimp fabrics can be treated as two-layer unidirectional fabrics: one layer with 0°and another with 90°. The change of fabric thickness was then modeled as the sum of 0°and 90°unidirectional fabrics. To validate the theoretical model, experiments with 3, 4, 5 and 50 layers were carried out.
