Impact testing of laminated glass and composites
Jun LIU

With the promotion of energy conservation and emission reduction, composite materials are gradually taking the place of metallic materials in extensive applications especially in aviation industry. Meanwhile, thermoplastic composites are revealing their superiority to thermoset composites and receiving more attention from industries because of their high damage tolerance and strength-to-weight ratio.

For an optimal design of thermoplastic composites of aircraft structures and components, a better understanding of constitutive relations and failure mechanisms of thermoplastic composites is critical. Effect of types of resin matrix, ply configuration, geometry of projectile, manufacture processing, and mechanical properties of other laminated structures like hybrid laminates and sandwich structures can be investigated and performed by both low and high velocity impact, and numerical models will be established to predict their impact-resistant performance  if subjected to dynamic loading. Additionally, non-destructive testing (NDT) will be employed to assess mechanical properties of composites before and after impacts.
