Component Testing

Using a multi-purpose test bench, components can be tested under various loading conditions using a computer-controlled environment.  Tests can be performed under static, fatigue and quasi-impact loading.  In the photo, a carbon fiber bicycle fork is being tested under bending loads.

Bicycle tests performed using the AFNOR NF EN 14781 test standard

In order to fulfill the requirements of the standard, a bicycle frame needs to undergo two impact and two fatigue tests without visible cracks and must respect the envelope ruling the permanent deformation stated for each test. The tests should be performed on a frame/fork assembly. According to the standard, bicycle manufacturers need to perform at least the impact tests using the fork that will be actually sold with the bicycle frame.  Ideally, each of the four tests should use a new bicycle frame.

Standardized Testing of Composite Materials

Using calibrated MTS material testing systems, the standard material characterization tests can be performed for isotropic and composite materials.  Fiber tension, fiber compression, matrix tension, matrix compression, in-plane shear and interlaminar shear.  Tests can be performed under static or fatigue loading conditions.  Usually ASTM standards are followed for tests, however customized testing is also possible.
