Abstract
A composite has a laminar core assembly defining a bend, the bend having a radially inner surface defining a fillet. A reinforcement block adjacent to the radially inner surface of the bend has sufficient thickness to at least partly bury the fillet. The reinforcement block reduces the through-thickness tensile stress in the laminar core assembly and thereby reduces the risk of delamination.
