Flexometer

A flexometer is a machine that can be used to measure the flexural behavior of a material without damaging it. Flexometers test the buckling behavior of flexible materials such as leather , fabrics and composite textile goods, rubber and similar materials.

Course of an exam

The test material is clamped in the flexometer. The material is then bent at an adjustable speed and then returned to its original position. This process is carried out several thousand times depending on the material and the corresponding standard . For example, standards require leather for the automotive industry to withstand up to 100,000 kinks without damage.

Once the process is complete, the material is checked for visible changes. Other tests (e.g. tensile strength) can also follow.

Tests with the flexometer are for example in DIN EN ISO 5402-1: 2012-03 Leather - Determination of the fatigue strength - Part 1: Flexometer method (ISO 5402-1: 2011); German version EN ISO 5402-1: 2011 or ISO 4666-2 Rubber, vulcanized - Determination of temperature rise and resistance to fatigue in flexometer testing (ASTM D623) standardized.

textiles

The flexometer method or the flexometer test is also used to

the crease resistance or tendency of textiles to crease

the shape retention capacity of inserts in outerwear (e.g. nonwovens )

the long-term flexural strength of textiles coated with rubber or plastic ( textile laminates )

to determine.
