Elastomeric grips are used to evaluate the strength of bandages in tension.
The Challenge
Bandages are a commonly used product whose materials and designs are characterized
by their ability to carry a tensile load - i.e., how much force they can withstand
before failure occurs in tension. Measurement of mechanical properties allows evaluation
of bandage performance while providing insight for manufacturing processes and quality
control.
Our Solution
A standard tensile test is used to evaluate tensile strength and elongation at break,
two important parameters in product development and quality control. However, special
consideration must be given to testing these materials without causing unwanted
failures. Instron's elastomeric grips and pneumatic grips are suitable for testing
multi-stranded woven materials used in bandages without causing premature failure
at the jaw faces.
Non-contacting strain measurement is required where highly accurate measures of
strain are necessary. Instron's video extensometer enables precise measures of elongation
without damaging the material under test.
