Method for producing a tennis racquet frame by moulding a flexible tubular element impregnated with resin comprising the operations which consist: in impregnating fibres with resin, in rolling up the said resin-impregnated fibres around a flexible casing arranged on a rigid mandrel driven in rotation, in which the flexible casing is a length L1, between 1200 and 1800 mm, and so that the lengths, the weights and the angles between 18 DEG and 42 DEG of deposition of the strands (tufts of fibres) are within the values indicated in the table below. <IMAGE>
