A method of manufacturing a component comprising a hollow axisymmetric body formed of a cured composite material is provided. The method includes the step of positioning the constituents of the composite material in a mold corresponding to at least a portion of the hollow axisymmetric body. The composite material is cured into a composite part, and residual stresses are generated in the composite material during the curing by controlling the temperature of the constituents in the mold. When the composite part is released from the mold, relaxation of the residual stresses causes one or more regions of the composite part to deflect in the radial direction of the hollow axisymmetric body, the position of greatest radial deflection of each region having a radial deflection which is at least 0.1% of the greatest diameter of the hollow axisymmetric body.
