Mechanical properties of asbestos-cement composites

Fibre Matrix void Modulus of Tensile Ultimate 

When considering the properties of asbestos-cement composites in relation to the production processes, the orientation effect must also be taken into account. The data reported by Allen indicate that the strength in the transverse direction is only about 60-85% of that in the longitudinal direction, with similar ratios reported for the ultimate elongation. Zevin and Zevin [9,10] determined the orientation of the fibres by X-ray methods. They then calculated the strength ratio between the longitudinal and transverse directions, which was found to compare favourably with
