Effect of ply-drop on stress and strain fields in tapered thermoplastic matrix composites

Popis výsledku v původním jazyce

The analysis of a ply-drop in carbon fibre reinforced thermoplastic composite with PPS matrix was carried out using numerical modelling. The results of fatigue tests yielded the ply-drop as a critical point when cyclically loaded in tension. Several delaminations were found in phractography in the area of the ply-drop. The finite element model was build using a ply-by-ply approach, that enables to evaluate the stress and strain fields in each lamina. The concentrations at the interface of terminated plies and resin rich region were identified. The terminating ply with orientation of 0/90° causes high stress concentrations of shear stress in connection with adjacent plies and high strains in resin rich region. The proper choice of terminated ply location can extend the fatigue behaviour considerably.
