The carbon strands will hold up to a squeezing (Normal) force of 658 lbf (for .044" diameter strand) and 785.6 lbf (for 0.030" diameter strand). This means that I need a material with a static COF of at least 0.74 on carbon fiber and will withstand a shear stress of at least 3150 psi.
Please...
The goal is to speed up the overall tensile testing process, including any cure time and other specimen prep time involved.
I am in the process of determining the fiber's transverse compressive strength, which will provide more information on how large the grip inserts will need to be to spread...
I'm trying to find a material for tensile test grip inserts for testing small diameter (~0.063" and ~.031") carbon fiber strands without using tabs. I need a high COF material that won't bite too hard into the specimen and cause failure in the grips, but will also withstand the specimen's...
