Abstract: Disclosed is a method and apparatus for the manufacture of a composite article. A composite lay-up is provided having a female radiused portion. The composite lay-up is compressed so as to reduce its thickness. Additional compression is applied to the female radiused portion.The additional compression reduces or substantially eliminates the bridging that might otherwise occur, and achieves a more consistent material thickness around the female radiused portion, and a more consistent and greater fibre volume ratio.
