Filament Winding
Continuous reinforcements, such as roving, are wound around a mandrel or core under tension, while being impregnated with a resin. Factors such as winding angle, fibre orientation, and layering of the fibres are each precisely controlled.
Vacuum Infusion / Bag Moulding / Vacuum bagging
A resin is drawn through a dry preform made of fibres / fabrics by means of a vacuum.
Resin Transfer Moulding (RTM), including High Pressure (HP-RTM)
Dry fibers / fabrics are placed in a closed mould, and then resin is introduced (various methods) under pressure to saturate the fibres and cure the composite structure.
Standard RTM, Vaccum Assisted (VA-RTM) and Compression (C-RTM) available.
CCP Gransden can also offer High Pressure RTM (HP-RTM); Used instead of standard RTM because it allows for the production of higher-performance and complex-shaped parts due to the increased pressure used to saturate the fibres and cure the composite structure.
Compression Moulding [Thermoplastic & Thermoset]
A matched male and female mould is employed. A measured amount of loading compound (fibre plus resin) is charged into the mould. A press, using heat and pressure, is used to cure the fibres and resin by closing the male and female halves of the mould. After the material is cured, the pressure is released and the part is ejected from the mould.
Injection Moulding
A thermoplastic or thermosetting material is heated and injected into a closed mold to form a solid object of the desired shape and properties.
Thermoforming
A thermoplastic composite material (usually a laminate) is heated to a pliable state, then shaped into the desired form using a mold.
Overmoulding
A polymer or resin is injected over an already existing substrate or part, to create a new layer or coating that enhances the original product. E.g. Combining thermoforming of pre-consolidated laminates with injection moulding compound
Single-Stage Overmoulding
In this single-stage process for overmoulding, both the thermoforming and over moulding injection processes occur simultaneously supporting sustainability, part reduction, and incorporation of ribs and net formed components. CCP Gransden has optimised this process.
Hand Lay-up / Wet Lay-up
The most widely used process for manufacturing composites worldwide. Fibre reinforcement and resin are manually placed and layered by hand.
Prepreg Lay-up
Akin to conventional Hand Lay-up, the basic difference being that when using prepreg the impregnation of the fibres is made prior to moulding.
Continuous Fibre Carbon 3D Printing
Robotically layering and curing liquid resin reinforced with continuous carbon fibers.
N.B. Small scale capacity at CCP Gransden. Suitable for small prototypes and low volume production.
Installation / Maintenance Repair and Overhaul (MRO)
Where required, CCP Gransden's team will travel to complete works at the desired location.
