Exclusive Development for Dutch Carbon
Infusion technology for the hull of the DC 36'

Infusion of the Dutch Carbon 36' hull

The pictures show the preparation of the dry lamination, application of tubes and vacuum bag and the infusion (injecting with resin under vacuum) of the hull. The mould is heated (that is why it looks like a 'stealth' structure), which allows us to inject the resin at an elevated temperature. This reduces the viscosity of the resin which results in a better impregnation of the carbon.

All the epoxy resin (185 kg was injected, of which 45 kg in tubes and mesh) is degassed under vacuum. This improves the quality of the laminate by reducing the number of voids. Total weight of the hull, e.g. carbon, foam core and epoxy resin is only 400 kg.

The injection strategy (location of feeding lines, resin inlets and vacuum lines) has been developed with the aid of the RTM-Worx flow analysis software. Click on the image below for an animation of the filling process as predicted by RTM-Worx.

Note that a rectangular area in the neighbourhood of the keel plate is isolated by the feeding tubes and fills much slower. The reason is that this part does not have a foam core, but is a thick (10 mm) single skin laminate.
