Design Procedures for Improved Laminate Performance in Bending and Extension

Lee, H.S.J. and York, C.B. (2019) Design Procedures for Improved Laminate Performance in Bending and Extension. 22nd International Conference on Composite Materials 2019 (ICCM 22), Melbourne, Australia, 11-16 Aug 2019.

Abstract

This article discusses improved laminate performance relating to both in-plane properties (e.g. first ply failure) and out-of-plane properties (e.g. initial buckling) using double angle-ply laminates (with ±y and ±f ply orientations), which are stiffness matched to standard laminate configurations. A procedure for producing isotropic laminates in bending, is first employed. Off-axis orientation is then applied to these designs to maximise Extension-Shearing coupling; bending isotropy is unaffected by off-axis alignment, hence buckling performance is also unchanged. The performance of competing Extension-Shearing coupled designs are then assessed against a first ply failure strength criterion.
