A method of manufacturing a woven fancase comprising the steps of: wrapping a contour woven fabric (202, 203) around a centerline one or more times to form a preform base having a circumferential base surface around said centerline with a first flange formed on a first edge of the base surface and a second flange formed on a second edge of the base surface; wrapping a contour woven fabric (401, 402) about the centerline to form a first sub-preform stiffener with a first sub-preform stiffener base around said contour woven fabric (202, 203), the first sub-preform stiffener having a first sub-preform stiffener flange on a first edge of the first sub-preform stiffener base and a first sub-preform stiffener flange on a second edge of the first sub-preform stiffener base so that said first sub-preform stiffener flange on a first edge of the first sub-preform stiffener base abuts the first flange and the first sub-preform stiffener base abuts said circumferential base surface; and wrapping a contour woven fabric (405, 406) about the centerline to form a second sub-preform stiffener with a second sub-preform stiffener base around said contour woven fabric (202, 203), the second sub-preform stiffener having a second sub-preform stiffener flange on a first edge of the second sub-preform stiffener base and a second sub-preform stiffener flange on a second edge of the second sub-preform stiffener base so that said second sub-preform stiffener flange on a first edge of the second sub-preform stiffener base abuts the second flange and the second sub-preform stiffener base abuts said circumferential base surface, wherein the first sub-preform stiffener flange on the second edge abuts the second sub-preform stiffener flange on the second edge. wrapping a contour woven fabric (202, 203) around a centerline one or more times to form a preform base having a circumferential base surface around said centerline with a first flange formed on a first edge of the base surface and a second flange formed on a second edge of the base surface; wrapping a contour woven fabric (401, 402) about the centerline to form a first sub-preform stiffener with a first sub-preform stiffener base around said contour woven fabric (202, 203), the first sub-preform stiffener having a first sub-preform stiffener flange on a first edge of the first sub-preform stiffener base and a first sub-preform stiffener flange on a second edge of the first sub-preform stiffener base so that said first sub-preform stiffener flange on a first edge of the first sub-preform stiffener base abuts the first flange and the first sub-preform stiffener base abuts said circumferential base surface; and wrapping a contour woven fabric (405, 406) about the centerline to form a second sub-preform stiffener with a second sub-preform stiffener base around said contour woven fabric (202, 203), the second sub-preform stiffener having a second sub-preform stiffener flange on a first edge of the second sub-preform stiffener base and a second sub-preform stiffener flange on a second edge of the second sub-preform stiffener base so that said second sub-preform stiffener flange on a first edge of the second sub-preform stiffener base abuts the second flange and the second sub-preform stiffener base abuts said circumferential base surface, wherein the first sub-preform stiffener flange on the second edge abuts the second sub-preform stiffener flange on the second edge.
