Abstract
A fiber reinforced composite structure for transmitting high shear loads includes a laminate with an edge defining a buttress groove. The buttress groove includes a pressure flank oriented substantially perpendicular to a longitudinal axis of the structure to transmit shear loads in one direction only. The laminate is formed of a plurality of plies having fibers disposed in a matrix material at angular orientations relative to the longitudinal axis of the structure. A first plurality of the plies have fibers oriented parallel to the longitudinal axis and a majority of the other plies have fibers oriented at an angle .theta. relative to the longitudinal axis corresponding to a direction of the largest tensile component of the shear load.
