Integrated loop technology (ILT) for seamless joints
One of CompoTech’s more recent R&D innovations has been the development of its integrated loop technology (ILT), incorporated into CompoTech’s in-house automated, one step, seamless joint manufacturing process for producing carbon fiber epoxy composites components. Carbon fibres are used with a wet epoxy resin winding process that utilises CompoTech’s Robot-assisted filament laying (RAFL) proprietary system.

CompoTech’s proprietary fibre winding and integrated loop technology (ILT) processes were used to manufacture the interconnected epoxy carbon frame bottom bracket shell, chain stay and top, head, down and seat tubular sections for its in-house development CDURO mountain bike.

The ILT joining process uses specially designed tooling, which is predominantly 3D printed in-house; by using customised ILT tooling, fully integrated joint holes with no breaks in the carbon fibres can be consistently produced. The ILT process eliminates the need for moulding heavier wall thickness sections around a fixture area and for any post mould drilling, opening up new design options and offering manufacturers a more cost-effective way to produce lightweight FRP composite components.  

To support this joining process technology development, recent investments have been made in a new, custom-designed, robot assisted filament placement machine for ILT, plus a new CNC lathe to enhance tooling production and for automated precision machining of a wide variety of components, including larger square beams in carbon, steel or aluminium. The new in-house produced filament placing machine will be fully operational by autumn 2021.   

Properties of CompoTech’s carbon composite beams enable CNC machining manufacturers to replace much heavier steel and aluminium gantries with a lightweight CF epoxy beam which provides significant in-service production, productivity and cost saving benefits.

CompoTech carbon fiber composite beams product range
While the company is known for composite solution engineering, CompoTech’s standard catalogues show the wide variety and type of square and tubular structures that can be produced, which can be adjusted to suit bespoke needs.  New carbon fiber epoxy square beam and tube designs and sizes have been recently added to meet growing demand from manufacturers of automated robot lines, handling equipment and machine systems. The latest range includes new internally supported carbon fiber composites beams specially designed for dynamic machine gantry applications.  

Standard square beams, produced from graphite and PAN carbon fibres using CompoTech’s innovative automated, robot assisted filament placement technique have 10-15% higher axial direction stiffness and up to 50% greater bending strength compared to an equivalent size conventional filament wound beam.  CompoTech offers various square beam designs, which includes ‘bolt together’ connector beams with hollow corners and beams with reinforced corners, as detailed with diagrams in the catalogue. Standard square beam lengths vary from between 2.3 – 5.0 metres depending on the size, which ranges from 60 sq. mm x 5mm wall thickness, up to 200 sq. mm x 8mm. 

Standard connected beam used for T-boom applications in press shop manipulation. T-joint and attachments are made by bolting to the inserts placed in the corners of the profile.

CompoTech’s carbon fiber epoxy round tubes are manufactured using PAN carbon fibres. Standard CF tubes are between 3.6 – 7.8 metres long depending on the inside diameter, which ranges from 10mm x 2mm wall thickness up to 428mm x 4mm.
