Studies on bond strength of adhesive resin cement using pull out test.

Abstract

The purpose of this research was to determine optimal specimen size for Pull-Out Test and to determine the bonding strength of adhesive resin cements to the metal(SUS 304). Three experiment were carried out using Panavia EX (PE) and Superbond C&B (SB).The following results were obtained. 1. Breaking load increased with increasing length of the adhesive surface, and there was a significantly chose correlation between the length of the adhesive surface and breaking load in the specimen of a 10 mm in diameter.2. The bond strength of PE was not influenced by the length of the adhesive surface when the diameter was 10 mm, whereas bond strength decreased with increasing length of adhesive surface when the diameter of SB was 6 mm.3. The photoelasticity experiment revealed no difference in stress distribution, shear stress and the maximum stress between PE and SB.4. The diameter of the specimen had an influence on the stress distribution and maximum stress. The specimen of 10 mm in diameter showed a shear stress distributed up tothe superior region of the adhesive surface and maximum stress was a small value.
