Abstract
Delamination is failure in a laminated material, often a composite, which leads to separation of the layers of reinforcement or plies. Peel testing is one way to characterize adhesive bonds. It is used extensively to evaluate the bonding strength of tape, adhesives and flexible substrates. The peel test is used to determine the adhesion between soft (Adhesives & PVB) and hard (Glass, fiberboard, steel and liner material) materials. Peeling test is the practice of testing adhesion properties of film bonded to a substrate. The designed peel test setup uses Universal Testing Machine (UTM) as the measuring aid and the setup is assembled onto it. The setup ensures minimum friction during the sliding motion. The voluntary motion of the sliding plate eliminates the use of a motor or a separate mechanism to enable horizontal motion. The support block and buck mechanism serve their respective purposes for the test to be carried out. The setup is connected to a computer that has ‘Win UTM’ software to convert the experimental results into numerical data required for further analysis.
