Original Abstract

The paper deals with the influence of temperature and cyclic loading on adhesion and transparency of the adhesive joint consisting of soda-lime-silica glass and polycarbonate (PC) bonded with polyurethane (PU) adhesive film. The tested joint represents critical part of transparent armored glass used in vehicles. Dynamic tension creep tests were performed at temperatures to which armored glass is commonly exposed (25, 50, 60, 70, and 80 degrees C). Sawtooth loading mode was performed to 650N and the sine loading in the force range 0-1550N. The aim of the paper was to discover conditions causing delamination of the adhesive joint and glass milky appearance during the use. Delamination of soda-lime-silica glass/PU adhesive interface occurred at 25 degrees C after load to 1550N without the change of transparency. Both dynamic and static tension creep tests performed to 400N led to plastic deformation of PU adhesive at and above 70 degrees C, in preference at both ends and circumference edges of adhesive joint, and thus, to loss of transparency, but extent of deformation differed. Milky maps observed after sawtooth load to 650N at 80 degrees C reflected delaminated areas of highly deformed PU adhesive. Temperature of 70 degrees C was found out to be the critical parameter being in synergy effect with different thermal expansion of PC and PU adhesive.
