dc.description.abstract |
The mechanical properties of z-pinned composite laminates were examined
numerically. Finite element calculations have been performed to understand how
the through-thickness reinforcement modifies the engineering elastic constants
and local stress distributions. Solutions were found for four basic laminate
stacking sequences, all having two percent volume fraction of z-fibres. For the
stiffness analysis, a micromechanicalfinite element model was employed that was
based on the actual geometric configuration of a z-pinned composite unit cell.
The numerical results agreed very well with some published solutions. It showed
that by adding two percent volume fraction of z-fibres, the through-thickness
Young’s modulus was increased by 22-35 percent. The reductions in the in-plane
moduli were contained within 7-10 percent. The stress analysis showed that
interlaminar stress distributions near a laminate free edge were significantly
affected when z-fibres were placed within a characteristic distance of one z-
fibre diameter from the free edge. Local z-fibres carried significant amount of
interlaminar normal and shear stresse |
