Abstract
An approach to increasing the loading ability of adhesive joints by adding reinforced pins is presented. Following procedures are taken for making adhesive joints with reinforced pins: At first, holes are drilled at the overlap region of adherends, and then one hole is filled with a metal pin and adhesive. At the same time, adhesive is also applied on the surfaces of the overlap of adherends. After cured, the metal pin and the adhesive in one hole form an adhesive-metal reinforced pin. In this study, strengths of single-lap adhesive joints with the reinforced pins were measured experimentally. It is found that to well-bonded joints, (1) the strength of single-lap adhesive joints with adhesive-metal pins are obviously greater than those without adhesive-metal pins; (2) the strength of single-lap adhesive joints with adhesive-metal pins is highest when the pins are located at the positions of 5mm from the two ends of the overlap segment, the strength of single-lap adhesive joints with adhesive-metal pins is lowest when the pins are located at the middle of the overlap segment, about 10mm from the two ends of the overlap segment.
