The cryogenic interlaminar fracture toughness of woven glass-epoxy laminates was measured under mode I loading using double cantilever beam (DCB) tests. The tests were performed at room temperature (R. T.), liquid nitrogen temperature (77K) and liquid helium temperature (4K) to evaluate the effect of temperature and geometrical variations on interlaminar fracture toughness. The fracture surfaces were examined by scanning electron microscopy to verify the failure mechanisms. A finite element model was used to perform the delamination crack analysis. The results of the finite element analysis are utilized to supplement the experimental data.
