Novel method for interlaminar reinforcement using polymer/fibre pins

A common theme in the application of through-thickness reinforcement is desire to minimize/eliminate any reduction in-plane properties. In this work a novel method introduced using polymer/fibre pin. Similar concept traditional metalworking process riveting these pins are placed through thickness with deliberate excess length. The heat and pressure deforms exposed ends pin against part surface. resultant preform maintains its shape may be re-formed further conforming desired shape. Samples manufactured tested under quasi-static tensile loading show no significant change properties due addition. mode 1 refinement manufacture required, shallow angles resulting sub-optimal performance.
