Abstract : This investigation was initiated to determine the insulating value of .040 inch 91-LD fibreglass bonded to a stainless steel sheet. The shear strengths of PR-1421 adhesive which was employed to bond the laminate to the steel became a critical factor in the study. Test coupons were prepared and subjected to high temperature flames directed against bare steel coupons and against the laminate protected samples. The ability of the laminate to remain intact and protect the steel skin was measured. The effect of the high temperatures upon the adhesive was also measured. The temperature rise was followed by thermocouples and recording millivoltmeters. It was found that the initial rate of rise of temperature of the bare steel was about ten times as fast as the steel protected with laminate. A large number of photographs, tables and graphs present the information visually. The shear strength of the adhesive was measured at the temperatures from ambient to that which were found to exist during the flame heating. (Author)
