Abstract:

The mechanical properties of several GLARE laminates were investigated as part of an AKZO-coordinated round robin evaluation program. Tensile, floating roller peel, and three-point bend tests were performed on GLARE to determine its tensile properties, peel strength, and interlaminar shear strength, respectively. Strength, elongation to failure, and elastic modulus of the GLARE configurations tested in tension compared favorably to ARALL-4 and monolithic 2024-T3. Peel strength of ARALL-4 was found to be very low in the longitudinal fiber direction due to uninhibited crack front propagation along the fiberadhesive layer interface. The peel strength of GLARE was found to be ten times higher than for ARALL in the longitudinal direction. Three point bend tests revealed an interlaminar shear strength of over 70 MPa.
