Abstract: An apparatus (2) for forming a noodle (20) within an elongate groove (14) of a product is provided comprising an extrusion system comprising at least one extruder nozzle (4) through which noodle material (16) is extruded, at least one levelling device (6) adjacent the extruder nozzle (4) which levels the noodle material (16), and a gantry system which moves the extruder nozzle (4) and the levelling device (6) along the elongate product groove (14), such that noodle material (16) is extruded along the product groove (14) and is levelled to form at least part of the noodle (20) within the product groove (14).

Abstract: A resin transfer injection apparatus (1) for manufacturing a composite product is provided comprising first and second tools (7, 9), fashioned to at least partially correspond with first and second outer edges of the product, a preform assembly (11), comprising a product preform (12) fashioned to define a shape of the product, fitted between the first and second tools, at least one heater which allows the first and second tools (7, 9) and the preform assembly (11) to reach at least a predefined temperature, at least one spacing device to form a first cavity (19) between the preform assembly (11) and the first tool (7) and a second cavity (21) between the preform assembly (11) and the second tool (9), a tool movement mechanism for closing and opening the first and second tools (7, 9), at least one vacuum pump which establishes a partial vacuum between the first and second tools (7, 9), and a resin injection system which injects a volume of pressurised preheated resin simultaneously into the first and second ca

Abstract: A liquid shim includes a bag (24) defining a closed inner volume and having sealed openings spaced inwardly from a periphery of the bag. The sealed openings are sealed from the closed inner volume and delimit holes extending through the bag. A liquid shim material (22) is flowable through the closed inner volume around the sealed openings and is curable to form a solid. The liquid shim material has a liquid shim material volume being less than the closed inner volume of the bag. A method of creating a liquid shim, and a method of shimming a gap between components, is also disclosed.

Abstract: In the manufacture of a noise attenuation panel for an aeroengine nacelle an adhesive film is applied to a front face of a cellular component of the panel. The adhesive film is caused to reticulate to the ends of the walls of the cells at the front face of the cellular component. A perforate facing component of the panel is bonded to the front face of the cellular component by adhesive flow from the cell walls to the facing component. To avoid unpredictable adhesive flow giving rise to cosmetic spots on the front face of the facing component the two components are brought together with the interposition of an adhesive flow control sheet and the reticulated adhesive caused to bond the two components together by adhesive flow under the control of the adhesive flow control sheet.
