Abstract
A manufacturing method of a fiber reinforced composite member includes the steps of: forming a fabric 1 on the surface of a mandrel 10, infiltrating the formed fabric with matrix, and leaving portions 12a, 12b of the mandrel as integral with the fabric and removing the mandrel before the fabric adheres to the mandrel by matrix infiltration. Subsequently, a remaining portion of the mandrel is used as a reference surface and machining is performed. Without possibility of adhesion to the mandrel and resulting breakage, machining bases (axial center and reference surface) during machining can accurately be provided, and this can largely enhance machining precision and yield of the final product.
Claims4
A manufacturing method of a fiber reinforced composite member comprising steps of:
- forming a fabric by weaving fibers on the surface of a mandrel, wherein the mandrel comprises a reference segment and a forming segment;
- infiltrating the formed fabric with matrix to make a fiber reinforced composite member with the fabric integral with the reference segment of the mandrel;
- and
- leaving the reference segment of the mandrel that is integral with the fabric and removing the forming segment of the mandrel from the fiber reinforced composite member.
