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.
Claims20
A composite laminate comprising a plurality of plies of reinforcing fibers;
- at least some of the plies having 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 having reinforcing fibers oriented at ±β with respect to the axis of primary loading, where β is between 50 and 85 degrees.
A composite beam comprising plies of α-reinforcing fibers oriented at ±α with respect to an axis of primary loading, where α is between 2 and 12 degrees;
- and plies having β-reinforcing fibers oriented at ±β with respect to the axis of primary loading, where β is between 50 and 85 degrees.
A system comprising a beam including a base and a web, the web including plies of reinforcing fibers for providing strength in tension and compression along an axis of primary loading, the web also including plies of reinforcing fibers oriented at ±β 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.
