Abstract

The work describe here is part of an on-going study addressing Mechanically Coupled (Composite) Laminates. 24 distinct classes of coupled laminate have previously been identified, containing all possible interactions between Extension, Shearing, Bending and Twisting. These laminate classes were derived for UD material using (but not restricted to) combinations of standard fibre angle orientations, i.e. 0, 90 and/or ±45. The derivation of these laminate classes involves the added restrictions that each layer in the laminate: has identical material properties; has identical thickness and; differs only by its orientation. This presentation focuses on important aspect of laminate designs, including taper and ply contiguity, firstly for UD material and then for thin-ply Non-Crimp Fabric and Woven cloth materials, in which: stacking sequence symmetries are unconstrained and; the coupling matrix, B = 0.
