A discontinuous fibre reinforced composite consists of 20mm long carbon fibres in a polymer matrix. The volume fraction of the composite is 0.5, interfacial shear strength 5MPA and the critical fibre length 2.5mm. The fibre modulus is 250GPA and strain to failure 1.5%. The matrix modulus is 3.5GPa and failure strain 10%. If the ultimate fibre strength = 3500MPa, calculate the average failure stress in the composite.

An aligned and continuous fiber reinforced composite consists of fibers with an elastic modulus of 255 GPa and a matrix with an elastic modulus of 2.7 GPa. If the fibers are required to carry 98% of the total load in the longitudinal direction (isostrain condition), determine the volume fraction of the fibers and matrix needed to accomplish this task. Also, determine the composite modulus of elasticity for this case.
A composite primary steel beam with a span of 8m supports a secondary beam at midspan, which applies an characteristic (unfactored) load of 239kN to the primary beam. What elastic modulus (in cm³) does the beam require to be able to carry the load if the allowable stress due to the characteristic loads is 210N/mm2? It may be assumed that the elastic modulus required for the composite beam is 63% of that required for the equivalent non-composite beam.
