Abstract: Disclosed is a vacuum apparatus for applying a vacuum to a reinforcement lay-up during in composite manufacture, and a method of use. The vacuum apparatus comprises a vacuum port component (100) having body portion (102) defining a contact surface (104) and an internal cavity. A vacuum port (108) for connection to a vacuum pump is oriented away from the contact surface communicates with the internal cavity. The vacuum port component can be connected to vacuum component (200) body portion also defining a contact surface and an internal cavity (207), and further comprising a plurality of inlet apertures or slots (206) extending therethrough and in communication with the vacuum component internal cavity.

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.

Abstract: Disclosed is a method of curing a composite article and associated curing apparatus. A heat source is provided for heating the composite article. A temperature related property is detected proximal to the heat source and the heat output is regulated to a predetermined temperature vs. time profile. Heat output vs time data is acquired and functionalised and the curing completion time is determined based on the functionalised heat output vs time data. The method provides for heating a composite article so as to follow a predetermined temperature vs. time profile (i.e. a cure profile) and avoid excessively high temperatures. The required heat output vs time has also been found to be broadly reproducible, and the curing completion time can be more readily determined from functionalised heat output vs time data, for example by identifying reproducible characteristics of the functionalised data.
