Abstract
A composite laminate comprises a plurality of plies of reinforcing fibers. At least some of the plies have reinforcing fibers oriented at ±α with respect to an axis of primary loading, where α is between 2 and 12 degrees. At least some of the plies have reinforcing fibers oriented at ±β with respect to the axis of primary loading, where β is between 50 and 85 degrees.

degrees with respect to the axis of primary loading, where β
is between 50 and 85 degrees, wherein the fibers oriented at ±
β
degrees are biased towards outer surfaces of the web to increase stiffness in buckling and transverse loading. - View Dependent Claims (17, 18, 19, 20)
