ABSTRACT:
A method of manufacturing a preform from uncured multiple laminates of resins impregnated fiber reinforced composite material is proposed. The preform has irregular shape such that at least one edge of any transverse cross-section of the preform varies along its length with respect to a reference co-ordinate set of axes, and further such that the cross sectional area of every cross section of the preform along the length of the preform is predetermined. A layup is formed to a length substantially equal to that of the preform from uncured multiple laminates of resin impregnated fiber reinforced composite material to have a regular shape such that no edge of any transverse cross-section varies along its length with respect to the reference co-ordinate set of axes. The cross-sectional area of every transverse cross-section of the layup along its length is substantially equal to a predetermined corresponding cross-section of the preform. The layup is placed in a tool having a part including a cavity defining part of the shape of the preform, and cold compacted or coined to fill the cavity thereby transforming the layup into the desired shape of the preform.
