Specialized Fixtures and Grips for Tear, Peel, and Puncture Testing

Description

Specialized grips and fixtures are used for tear, peel, puncture, pull-through, buckle, and other non-standard mechanical tests where conventional tensile or compression grips are not suitable. These configurations are designed to match specific material behaviors and specimen shapes.

Peel testing setups include 90-degree peel fixtures and climbing drum peel fixtures for evaluating bond strength in adhesives, laminates, tapes, and layered assemblies. Tear testing grips are used for plastic films, fabrics, and other flexible sheet materials to study tear propagation. Puncture testing fixtures include systems for geomembranes under ASTM D4833 and ball burst devices for textiles in accordance with ASTM D3787.

Additional configurations include eyelet pull-through grips, buckle testing fixtures, and custom shear fixtures such as adhesive lap joint setups following ASTM D4501. These fixtures are used in packaging development, textile and film manufacturing, materials testing laboratories, and product engineering environments that require controlled testing beyond standard tensile or compression methods.
