Nonlinear ultrasonic testing of carbon fibre reinforced

Carbon fibre reinforced plastics (CFRP) are applied as a light-weight construction material. In their lifespan in service CFRP components are exposed to variable loads, which can amount to 10 11 load cycles. It is therefore important to examine the fatigue of CFRP materials in the very high cycle regime (more than 10 7 loading cycles).

Machining Carbon Fiber: Quick Guide [ Composites,

Fiber orientation is also important to be aware of when machining carbon fiber and composites. Where possible, the material is damaged the least if you can machine parallel to the fibers. Of course it's often impossible to do so exclusively, but it's worth being aware that machining parallel gives the least amount of fraying, chipping, and delamination.
