This improves efficiency and reduces operating costs of the equipment. Two-point bending is most useful for testing comparatively strong fibers. Very weak fibers can be tested using our Four-Point Bend Apparatus . While this equipment is more of a research tool than a production or quality assurance tool, we supply it to complement our other products. The fatigue behavior can be characterized by either static or dynamic fatigue testing.
Dynamic fatigue involves measuring the strength of the fibers as a function of the loading rate.
All the equipment described above can perform this type of testing. All our strength measurement equipment can be run in static mode but this is not usually the most effective way to perform static fatigue. We produce apparatus for performing long term static testing in two-point bending. Many fiber specimens can be inserted into precision diameter tubes and their failure can be monitored acoustically. Acoustic detection equipment, the Four Channel Trigger Box , is available together with precision bore tubes.
