Abstract

Various aspects related to fabrication and testing of fiber metal laminate (Glare) comprising 2014-T6 aerospace aluminum alloy sheets alternately bonded with, epoxy resin impregnated, E-glass fiber based composite prepregs are discussed in the paper. Procedures adopted in processing of laminate ingredients and in fabrication of the laminate are elucidated. Experimental techniques for measurement of mechanical properties of Glare viz. tensile, flexural and shear strengths and interlaminar fracture toughness are reviewed. Pertinent results are presented. Energy dispersive X-ray spectroscopy of aluminum alloy and optical microscopy and residual stress measurement in aluminum layer of the fabricated laminate are touched upon. Viability of laminate fabrication method is proved by theoretically checking the quality of interfaces between un-identical material layers of the laminate.
