Abstract: The present invention relates to a method of manufacturing an article. The method comprises forming a sealed shell of gas impervious material, the shell comprising a collapsible hopper portion opening to a main body portion. The main body portion and at least part of the hopper portion contain a powder material. Next, the method comprises applying vibratory energy to the shell and powder material to move the powder material from the hopper portion to the main body portion and to compact the powder material within the main body portion. Finally, the method comprises subjecting the shell and compacted powder material to isostatic pressure to consolidate the compacted powder material within the main body portion to form the article.

Abstract: A method of forming a fibre composite component (10), the method comprising: providing a plurality of first fibres (102), the first fibres (102) being arranged in a plurality of layers (104a-e) with an uncured thermoset resin matrix (106) being provided therebetween. The resin matrix (106) comprises a plurality of second electrically conductive fibres (108) suspended therein having a shorter length than the first fibres (102). The method comprises then applying an energy field to the resin matrix (106) to thereby align the second fibres (108) such that they provide an electrically conductive path between adjacent layers (104a-e) of first fibres (102) to form an electrically conductive fibre network comprising the first and second fibres (102, 108). The method comprises then inducing an electric current through the electrically conductive fibre network to thereby heat and cure the resin matrix (106).

Abstract: This invention concerns improvements in the polishing of internal surfaces and structures of components, particularly components with a complex internal geometry. Embodiments of the invention use an alternating current electromagnet (48) driven by a signal generator (50) to constantly alter the rheology of the magnetorheological fluid (5). An improved magnetorheological fluid (25,30) is also disclosed.
