Using simple rules of mixtures for fibre composite tensile modulus and density, an expression is derived for the optimum fibre content for beams and panels made from monolithic laminates, assuming a minimum stiffness / weight design criterion. Values are considered for a range of typical fibre types, including natural fibres, in the light of practically achievable fibre contents.
