X-Core is being used by the Durban University of Technology, KwaZulu-Natal,
South Africa in a new process that was developed to replace the polyurethane
and polystyrene used in the manufacturing of tools. At present, the University
is using this method to produce the tools for the hull of a new prototype
rowing boat. It is also significantly more cost-effective.
A CNC Router being used to cut X-Core into the desired shape. A twin-blade
cutting tool was used in this instance.
The tool is then used to smooth the surface of the core.
A paste is added to the top layer of the core which hardens,
allowing it to be routered.
A layer of pre-impregnated carbon
fibre is then applied to the surface. The carbon fibre will be the final
product and X-Core acts as the mould. It is “baked” for 12 hours at a high
temperature, to stabilise the carbon. The core retained the shape better than
any other tested material.
The carbon fibre can be removed
easily and used as a tool.
