Fibers misalignment factor

When the fibers are misaligned or where the direction of testing is not coincident with the fiber axis, then the fiber contribution in Eqs. 2-4 and 2-5 must be reduced. When fibers are randomly dispersed in a plane, the term is reduced to a third and if the fibers are randomly dispersed in three dimensions, the factor is one sixth. Thus a modified form of Eqs. 2-4 and 2-5, which contain an orientation factor K whose value may lie between 1 and 0.167, can be used ... 

When the fibers are misaligned, then a correction factor of similar form to that given in Eqs. 2-6 and 2-7 must be used.
