Carbon Fibre Tow
This is pure high strength carbon fibre in the form of a tow consisting of several thousand parallel strands of thin fibres - like a continuous hank of hair, but much finer. It can be embedded in a resin (or other) matrix for reinforcement or laminated within sheets to form composites. It can also be used experimentally to demonstrate the high strength of individual fibres. (Note: carbon fibre composites used in racing cars, cycles, canoes are virtually indestructible.)
