Injection Moulding

Injection moulding is a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. Material is fed into a heated barrel, mixed, and forced into a mould cavity where it cools and hardens to the configuration of the cavity. After a product is designed, usually by an industrial designer or an engineer, moulds Full Article…

Gelcoat

Gelcoat is a material used to provide a high-quality finish on the visible surface of a fibre-reinforced composite material. The most common gelcoats are based on epoxy or unsaturated polyester resin chemistry. Gelcoats are modified resins which are applied to moulds in the liquid state. They are cured to form crosslinked polymers and are subsequently Full Article…

Honeycomb Structures

Honeycomb structures are natural or man-made structures that have the geometry of a honeycomb to allow the minimisation of the amount of used material to reach minimal weight and minimal material cost. The geometry of honeycomb structures can vary widely but the common feature of all such structures is an array of hollow cells formed Full Article…

Spirit AeroSystems Create new Tooling Technology for Composite Structures
Spirit AeroSystems has announced it has been working with Spintech Ventures, of Xenia, Ohio, to develop a new configurable tooling technology for manufacturing complex composite aircraft structures. The solution uses re-formable, reusable mandrels to form complex, highly integrated composite structures, with features that are not possible with traditional tools. In 2005, Spirit AeroSystems began collaboration [...]The post Spirit AeroSystems Create new Tooling Technology for Composite Structures appeared first on Composites Today.
Northrop Grumman Completes Backbone of NASA’s James Webb Space Telescope
Northrop Grumman and teammate ATK have completed manufacturing of the backplane support frame (BSF) for NASA’s James Webb Space Telescope. Northrop Grumman is under contract to NASA’s Goddard Space Flight Center in Greenbelt, Md., for the design and development of the Webb Telescope’s optics, sunshield and spacecraft. When combined with the centre section and wings, [...]The post Northrop Grumman Completes Backbone of NASA’s James Webb Space Telescope appeared first on Composites Today.
ITT Exelis secures Composite Contract for F35 Lightning II program
ITT Exelis has been awarded a multi-million dollar contract from Lockheed Martin to fabricate composite blade seal components for all variants of the F-35 Lightning II program. This award will support production for LRIP 6 and 7 through 2015. Production of the blade seals will take place at the new Exelis composite design and manufacturing [...]The post ITT Exelis secures Composite Contract for F35 Lightning II program appeared first on Composites Today.
ATK Secures New Multi-Million Dollar Composite Contract from Rolls Royce
ATK have announced the award of a contract from Rolls-Royce plc, United Kingdom, to produce aft fan composite cases for the new Trent XWB-97 engine. The contract has the potential to grow to more than $200 million. This Rolls-Royce engine is the sole engine now available to power the Airbus A350-1000 aircraft variant. The life-of-type [...]The post ATK Secures New Multi-Million Dollar Composite Contract from Rolls Royce appeared first on Composites Today.
