In this paper, the effect of the winding angle and the number of folds on the
delamination behavior of vinyl ester resin-fiberglass composites under mode-I loading was
investigated experimentally. Accordingly, double cantilever beam samples with 8 and 12 folds
and with different winding angles (±45°, ±55° and ±65°) were cut out of industrial pipes and
subjected to mechanical tests. Furthermore, thick films were introduced during the winding
process to create initial cracks of 50mm. The Mode-I fracture tests were conducted according to
ASTM D5528-94a standards. Results show that the [±65°] winding angle provides the best
delamination behavior and greater resistance to cracking compared to the [±55°] and [±45°]
winding angles. Results also show that the number of folds has no effect on the initiation of the
crack stage, but it significantly affects the propagation stage.
