Abstract

The loading rate sensitivity of Mode I delamination initiation in a z-pinned woven composite laminate is studied. High-rate delamination was initiated using a Wedge Insertion Fracture method on a Kolsky Bar apparatus, and the crack initiation was monitored using crack detection gauges. It is determined that fracture initiated near the peak load recorded in the transmission bar regardless of rate. Comparison of load at fracture initiation with loading rate shows that as loading rate increases, the load at fracture initiation also rises. It is also shown that load at fracture initiation rises with pin density.
