Abstract
Strong Cosserat elastic effects are observed in a designed composite consisting of unidirectional corrugated tubes in a hexagonal array. The torsional characteristic length is much larger than the tube diameter. The effective coupling number N approaches its upper bound of 1. Extremely large size effects are observed, about a factor of 128 in torsion.
