NTPT and EPFL Research Discontinuous Fibre Composite Tubes

NTPT is collaborating with the Ecole polytechnique fédérale de Lausanne - Swiss Centre of Technology (EPFL) and other partners to research discontinuous fibre composite tubes for high performance applications.

NTPT has been producing high-performance carbon fibre tubes using its patent pending method for manufacturing tubes with Thin Ply prepreg materials since 2016. Offering composite design engineers the freedom to position fibre plies at any angle and at any point in the tube’s length or thickness, NTPT’s winding technology is said to be unique in providing such high-resolution engineering capability.

In order to fully understand the behaviour and potential of such tubes, the company is partnering with EPFL, a leading European technical university and specialist in research and technology transfer work in the field of composite materials. This latest project, NTPT and EPFL’s third collaborative research programme, reinforces their joint commitment to enhancing the performance of advanced composite structures enabled through Thin Ply technology.

The four-year study focuses on discontinuous fibre composite tubes for high performance applications, referring to NTPT’s proprietary manufacturing process for high performance tubes, which offers tighter tolerances, greater repeatability, as well as a high level of customisation and design freedom. The key aim of the study is to move the potential of tubular discontinuous fibre composites to a new level. It will aim to create a strong scientific knowledge base, and develop the technical tools required to create design rules, optimise the material and continue to look at the cost effectiveness of the process.

Carbon fibre composite tubes can be used in various market sectors and applications; thin wall tubes in the aero sector as struts or control arms, automotive drive shafts, masts and booms in the marine sector; rollers and cylinders for industrial applications; as well as for the performance sports sector, in particular golf, for which NTPT is establishing a new business under the TPT Golf brand. On a larger scale the technology may be applicable to the automated manufacture of wind turbine spar and root components. Two components will be developed through the course of the study. One short term project is a windsurf mast which will be developed over an 18-month period in conjunction with professional windsurfer Tristan Algret. The other is a three-year project with a leading aerospace company to develop tubular structures for UAVs.

“We are embarking on an exciting project that is the obvious next step in our research and development into high performance composite tubes,” states James Austin, CEO, NTPT. “We have established a sound platform from which to launch our parts business, and we are excited about the progress made this year. Now is the time to move into this next stage of research, which will allow us to more easily provide customer-specific responses to new applications and enquiries, and enable us to move into the prototyping stage of new products more quickly.”
