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.
