Abstract
The adhesive bonding system is chosen, applied and, where appropriate, crosslinked so as to have a critical energy release rate in mode I (tension) greater than 1500 J/m2 and a critical energy release rate in mode II (shear) greater than 2000 J/m2. The composite sheet is easily drawable to form parts requiring no curing after forming.
