Fiber reinforced composite materials are gaining more and more share of structural materials market with the maturation of composite manufacturing technologies. In addition, new fibers, both manmade and natural, with better properties are being developed. It is important to understand the performance of these fibers. Fiber testing encompasses a range testing from mechanical testing, optical testing, chemical testing depending on the fiber type and applications. Structural fibers like carbon, glass, and some natural fibers needs only mechanical and sometime chemical testing, while optical fibers need in addition optical properties.
Structural fibers like carbon, glass, ceramic, polymer as well as natural fibers are tested in tension as single fiber or toes. Prepregs are tested in other modes like flexure, compression, torsion etc.
Capability – At TTL, we test carbon, glass, ceramic as well as polymer fibers like polyesters, aramids, and poly olefin fibers. We also have tested several natural fibers like cotton, flax, hemp, etc. We have capability to test singe fiber, toes, and fiber prepreg in tension, compression and shear mode. Occasionally it may be necessary to understand how the fibers bond to the matrix. We have the capability to evaluate this by either pulling or pushing a single fiber or a collection of fibers in a universal testing machine.
Some relevant standards:
Touchstone is committed to providing its customers with quality, reliable test results. That is why we have undertaken the rigorous steps needed to meet and secure the most stringent of test lab accreditations including ISO/IEC 17025, NADCAP 7101 (Materials Test Lab) and NADCAP 7122-I (Non-Metallics Materials Testing).
