Carbinge™ Test Data

October 2003 sheer (pull) testing

We performed this test with a .080" steel pin using a 2" wide (effective) piece of Carbinge™.

We were pleasantly surprised to find a limit load of 1,000 lbs. for this hinge sample. The hinge did not fail at this load, but the pin distorted very slightly. We have computed a new load rating based on this test. Carbinge™ is now rated at 3,000 lbs. per foot with a 100% safety factor. This is an increase of 300% over the former rating of 1,000 lbs. per foot.

CPM Results
Accelerated Wear 1.5 2400 no wear or breakdown detected
Extended Wear* 1.5 128 no wear or breakdown detected
End Bearing Wear test** 1.25 64 <0.0125" wear; no other sign of breakdown

* Vibration was added to the extended wear test to simulate flutter.

** The End Bearing Wear test included torsional (twisting) stress along the length of the hinge material.
