Abstract

The tennis racket frame is designed so that the sections of the structure surrounding the strings have a resistance enabling a certain degree of flexure near the handle. For this purpose, inside the two arms, a stiffening element is placed and it is preferably formed by a blade of wood or plastic. The frame is cast and the mould forms string holes by separation of glass fibres which form the frame. This avoids drilling operations which would weaken the frame by destroying some of the fibres. Therefore, for the same weight, the frame is more resistant. The frame is enclosed in a glass fibre mat impregnated with a polyester resin.
