General introduction

Cleavage Fracture Strength Shear Test fixture baed on ASTM D5041 used to determine the fracture strength in cleavage of adhesive bonds when tested on standard reinforced plastic specimens and under specified conditions of preparation and testing. 

ASTM D5041: Standard Test Method for Fracture Strength in Cleavage of Adhesives in Bonded Joints

Test Procedure: 
The ASTM D5041 test can be performed on any testing machine with a drive mechanism capable of imparting a constant and controlled velocity to a movable crosshead member. The specimen comprises two flat plates bonded by an intermediate adhesive layer. The specimen is fastened vertically onto a steel support baseplate. A stainless steel wedge with a removable tip performs the cleavage. A threaded coupling attaches the wedge base to the movable crosshead member of the testing machine. A notch is provided at the leading edge of the specimen to initiate crack propagation on the sample. The wedge is driven at a specified speed, and the crack propagation is measured.

Specimen size: 

Specimens consist of two flat plates bonded with an adhesive layer. The standard size of specimens is 200 mm in length and 25 mm in width, with adherend plates about 2 mm thick. 
Sample Number: At least 5 pcs.
