Abstract
A method and apparatus for making a composite component. For making a non-cylindrical composite component such as a nozzle, a longitudinal winding of at least one fiber strand impregnated with resin is applied onto a generally cylindrical mandrel at a predetermined angle relative to a line parallel to the mandrel rotational axis. A transverse tape is then spirally cut from the layer and wound onto a component mandrel. The wound transverse tape is then compacted and cured and the mandrel removed. A nozzle exit cone is also disclosed made from such transverse tape so that the fiber strand portions are short enough that they do not follow the curvature of the nozzle and thereby peel. The windings are shingled onto the nozzle exit cone so that only one end of each of the fiber strand portions is exposed to the nozzle surface. The fiber strand portions are oriented at a predetermined angle which may be optimized for erosion resistance and stress requirements. In order to form a cylindrical composite component, a cylindrical component mandrel is rotated about its rotational axis in a stationary position, at least one transverse tape of resin impregnated fiber strand portions is supplied …
