Macroscopy and Correlation with Mechanical Data of Impact Failed Partially Bonded Glass/Epoxy Two-Layered Pieces

摘要: Abstract Two flat glass/epoxy test pieces were adhesively bonded to varying degree along the common width face starting from either ends yield a set of samples i.e., sparsely bonded, moderately and fully ones. The thus prepared subjected low velocity impacts. Impact data show total energy peak load registering values for case value increasing as bond area increases. Further, stiffness parameter also showed gradual with an enhancement in level interfacially introduced area. However, regards deflection, discernible trend reversal was noticed that it high Fractographic analysis ones displayed through thickness crack propagation, tensile outward fiber failure protrusion feature on one while debonding end region, split wide opening t...
