A composite material is being produced with the fibres aligned in a single direction. The fibres have a Young's modulus of 115 GN/m2 and a Poisson's ration of 0.27. The matrix material has a Young's modulus of 10 GN/m2 and a Poisson's ration of 0.36. The fibres take up 50% of the volume of the material. Calculate Poisson's ratio V12 where 1 is the fibre direction. Your Answer: Answer
