Abstract
Theoretical predictions have been made of the effect of fibre orienta tion and laminate geometry on the flexural and torsional damping and modulus of fibre reinforced composites. Materials with fibres at + θ (off- axis), ±θ (angle-ply), 0/90° (cross-ply) and a general plate were in vestigated. In almost all cases, very good agreement was obtained between the theoretical prediction and the experimental results. Some limitations of plate theory for the torsion of angle-ply laminates were revealed and discussed.
