Novel ultra high impact strength light weight transparent polycarbonate laminated composite for aviation and defence

High impact resistance transparent materials are still a challenging task in respect of its strategic applications. Increasing the impact resistance of the polycarbonates have always been the focus of the material manufacturers for years. This study provides an effective solution to the bird strikes on aircraft by utilizing solvent vapor bonding to make the polycarbonate laminates that can be used in wind- shields. Dichloromethane has been proved to be the best solvent for solvent vapor bonding process from Lap Shear Tensile tests as the bond made is of high strength. The effective bonding in the solvent vapor bonded is much greater than the bonding in normal windshields greatly increasing the impact resistance of windshields by fifty percent along with the retention of transparency in the material. The toughness of the material after solvent vapor bonding is increased by fifteen times. The entire process of making the polycarbonate laminates for aviation and defence applications has been discussed in great depth.
