High-speed observation of bending fracture process of carbon fiber reinforced plastic composite/Nomex™ honeycomb sandwich panel

Failure mechanism of sandwich panels is very complicated. The objective of this study is to demonstrate the usefulness of high-speed observation to elucidate the failure mechanism of sandwich panels. Failure processes of carbon fiber reinforced plastic composite/Nomex™ honeycomb sandwich panels were observed using two synchronized high-speed cameras with an 8 µs frame rate. The sandwich panel was subjected to a four-point bending load in...
