The effect interleaving has on thin-ply non-crimp fabric laminate impact response: X-ray tomography investigation

A strategy to improve the damage resistance of thin laminates is to interleave non-woven veils into the interlaminar regions. In their paper The effect interleaving has on thin-ply non-crimp fabric laminate impact response:
X-ray tomography investigation, S.M. García-Rodríguez et al. present interesting results obtained with two types of co-polyamide veils that have been tested with QSI and CAI. As observed with X-ray tomography, the melting of veils during manufacturing has a positive influence on reducing the damage area and on improving the CAI strength.

Highlights

  • We investigated how interleaving affects the impact resistance, tolerance and sequence of damage events of thin laminates manufactured with thin-ply non-crimp fabrics
  • Interleaving one type of polyamide veil prevents the initiation of delamination during impact and improves the CAI strength by up to 28%
