Velcro Fatigue Tester – Ensuring Longevity of Hook-and-Loop Fasteners

Introduction

The Velcro Fatigue Tester is a critical device for evaluating the durability of hook-and-loop fasteners, commonly used in footwear, apparel, medical braces, and automotive interiors. Repeated engagement and disengagement can weaken these fasteners over time, leading to failure. This tester simulates real-world usage to predict lifespan and performance.

How It Works

The tester repeatedly opens and closes the Velcro strip under controlled conditions, measuring the loss of gripping force. Key parameters include:

• Cycle count (typically thousands of cycles)

• Peel force measurement (to assess strength degradation)

• Shear force resistance (for side-load applications)

Industry Applications

• Footwear: Ensures straps on shoes and sandals remain secure.

• Medical Devices: Tests braces and orthopedic supports for reliability.

• Automotive: Evaluates seat covers and interior trim fasteners.

Compliance & Standards

The tester complies with ASTM D5169, ISO 22776, and other industry standards, ensuring consistent and repeatable results.
