Lap Shear Strength Tester for Adhesive Bonds

Universal tester with lap shear grips and fixtures for measuring the shear strength of adhesive joints between metal, plastic and composite substrates. Used in automotive, aerospace and electronics bonding labs.

Specification

Single lap joint specimens are loaded in tension at controlled rate until the bond fails, and the peak load divided by overlap area gives the shear strength in MPa. The result is a standard way to compare structural adhesives and surface treatments. Self-aligning grips and shims keep the load path correct.

Features

• Capacity 20 kN with accuracy class 0.5
• Self-aligning wedge grips with shims
• Test speed 1.3 mm/min as per ASTM
• Software with shear stress calculation
• Environmental chamber compatible
