Abstract
A method of making a fibre-reinforced molded racquet frame is disclosed. The method comprises placing two cores each including a respective tube having at least one layer of woven reinforcing fibres in a mold shaped to define the frame. A respective core is positioned on each side of the split-line of the mold. A plurality of string-securing members are formed with each string-securing member comprising a first portion shaped to receive and position at least one string of stringing to be secured in the frame and a second portion adapted to be embedded in the frame. The string-securing member is supported such that, upon closure of the mold, the second portions are disposed inside the mold cavity and entrapped between the two cores while the first portions project out of the mold cavity into the area which will be surrounded by the mold frame. A plastics material is injected into the mold around the cores and the second portions of the string-securing members. The plastics material preferably has a relatively low setting temperature and a relatively low viscosity.
