Test Speed Dependence Evaluation of Shear Strength of Adhesive and Fracture Observation

User Benefits

- Test speed dependence evaluation of the mechanical properties of adhesives and fracture observation are possible. - High-speed tensile tests at up to 20 m/s can be conducted by HITS-TX. - High-speed video camera HPV-X2 enables high-speed imaging of up to 10 Mfps/sec.

Introduction

Adhesives are used for joining and fixing various components, as well as improving the watertightness and airtightness properties of joints in applications such as piping. Especially in the automotive field, adhesives are lighter compared with welding and bolting, and additionally, using the appropriate adhesive can also reduce the vibration and noise of components. Therefore, replacement with adhesives is being put into practical use to improve fuel efficiency. In the transportation field, including automobiles, it is considered important to evaluate the impact properties and the test speed dependence of the mechanical properties, as components may be subjected to impact loads. This paper presents a study evaluating the test speed dependence of shear strength for four types of adhesives commonly used in automotive applications, tested using high-speed impact testing machine HITS-TX.Additionally,by using the high-speed video camera HPV-X2, the progression of cracks during shear fracture could be observed.
