“…The twill 2 × 2 fabric has better drapability than a comparable plain weave fabric, making it more attractive to be used in components with complex 3D geometries [13,14]. For that reason, the use of caul plates was avoided as it might generally be less practical to use in those cases.…”

This paper presents the fabrication and 3-point flexion testing of carbon fiber reinforced polymer (CFRP) composite face/aluminum honeycomb core sandwich panels. Specimen sandwich panels were fabricated with three honeycomb types (3.18 mm, 4.76 mm, and 6.35 mm cell size) and three panel radii (flat, r = 1.6 m, r = 1.3 m). The curved sandwiches were fabricated normally with the core in the W-direction. The tensile mechanical properties of the CFRP 2 × 2 twill fabric face laminate were evaluated (modulus, strength, Poisson's ratio). The measured values are comparable to other CFRP fabric laminates. The flat sandwich 3-point flexion test core shear strength results were 11-30% lower than the manufacturer published data; the test set-up used may be the cause. With a limited sample size, the 1.3 meter panel curvature appeared to cause a 0.8-3.8% reduction in ultimate core shear strength compared to a flat panel.

“…A great literature is dedicated to those tests (Prodromou & Chen, 1997, Rozant et al, 2000, Potter et al, 2002, Lebrun et al, 2003, Sharma et al, 2003, Peng et al, 2004, Harrison et al, 2004, Lomov et al, 2006, Launay et al, 2008, Cao et al, 2008 mainly because the in-plane shear is the most dominant deformation mode in woven composite forming when the manufactured part is doubly curved. The shear angle can reach 50° (and even more in some cases such as presented in section 5.6).…”
