  Abstract

The 2/2 twill pattern represents a configuration of two-dimensional (2D) fabric weave. Composites reinforced with this architecture exhibit in-plane symmetry and balance, even as single layers, and offer superior formability. However, the inherent undulation of the interlaced yarns leads to reduced compressive strength. This study introduces an analytical approach to evaluate the compressive behavior of such composites. In the 2/2 twill configuration, both the warp and fill yarns comprise alternating straight and curved portions. The curved sections are treated analytically as beams resting on an elastic foundation. The model accounts for all three key structural components of the laminate, namely longitudinal yarns, transverse yarns, and the surrounding matrix. Load distribution among these constituents under compression is systematically assessed, and the internal stress field is computed. Progressive failure of elements is incorporated into the analysis. Experimental validation was performed using T300/5208 carbon/epoxy twill weave composite specimens.
