Abstract
The adhesive strength of butt joints subjected to impact tensile loads under high temperature was studied. The specimens are cylindrical butt joints. The electric furnace heats the adhesive joints. Three kinds of organic adhesives and one kind of inorganic adhesive were used. The impact adhesive strength of the organic adhesives decreased with the increasing of temperature. And the strength was approximately σ=0MPa at about T=200 ℃ even if it were heat-resisting organic adhesives. The strength of the heat-resisting inorganic adhesive measured at the T=200 ℃ , however, is equal to the strength measured at the room temperature approximately. Also the impact adhesive strength of the organic adhesive used in this paper was. much higher then the static adhesive strength.
