Abstract

Mixed-mode I/II fracture characterization and measurements of low temperature fracture properties for typical naval type sandwich material configurations has been carried out using the mixed mode bending (MMB) test fixture inside a state-of-the-art climatic chamber facility. The developed test methodology is utilized to measure mixed mode fracture toughnesses as well as crack propagation speeds (da/dN) vs. cyclic energy release rate data, investigating and comparing ambient and low temperature face/core fracture behaviour at different mode-mixities in Navy type sandwich composites. Sandwich specimens were manufactured using H100 PVC foam cores and E-glass/Epoxy face sheets. All specimens were pre-cracked in order to define a sharp crack front.
