ABSTRACT:
A method of manufacturing a fiber reinforced article using a fiber preform 10 suitable for impregnating with a curable resin to form the fiber reinforced article. The fiber preform 10 is formed by fitting a plurality of preformed seamless fabric envelopes 20 over an inner mold body 30 one over another in a layered fashion. An outer mold body 40 is placed over the completed fiber preform 10 prior to injecting a curable resin into the mold cavity 50 housing the fiber preform 10. The preform 10 comprises an innermost seamless fabric envelope 20A preformed to closely match a desired contour of the inner surface of the manufactured article, an outermost seamless fabric envelope 20B preformed to closely match a desired contour of the outer surface of the manufactured article, and an intermediate layer of at least one intermediate seamless fabric envelope 20C disposed therebetween.
