Abstract
A method of making leaf springs from fibre reinforced resin composite material, wherein a resin impregnated fibre assembly of a number of individual springs adjacent one another is moulded and treated to cure the resin and then cut into individual springs. The assembly is formed with depressions in the surface thereof along the lines where it is to be cut so the surface fibres remain undisplaced by the moulding process and hence undisturbed by cutting. The invention also provides a mould for treatment of the assembly of resin impregnated fibres including elements which form the surface depressions therein.
