The metal laminate is prepared by treating the surface with sandpaper, after which the laminate is then submerged in a salt bath for 10-15 minutes. The bidirectional glass fibre is cut into sheets and the sheet edges are then taped. Epoxy resin and hardener are mixed in the required ratio, after which aluminium and glass fibre sheet layers are stacked on top of one another alternately to form the FML. The laminate is then compression moulded to drive out any air bubbles present inside and subsequently left to cure for 24 hours.

The tensile & flexural properties are investigated in accordance with ASTM 3039 & ASTM D790 standards. Scanning Electron Microscopy (SEM) Analysis is conducted on the specimens in order to analyze the microstructure of the composites.

In cold water soaking, the specimens are aged at ambient temperature for 70 days. Specimens are taken out of the water once a week. In boiling water soaking, the specimens are oven-dried for a period of 12 hours at 100-110°C. The samples are then boiled for 2 hours and dried, in accordance with ASTM D5229M. The course of soaking and drying is repeated 10 times for 20 hours of boiling.
