A new platform for producing Class A surface quality components
Fig. 3: Clear-coated and piano-black painted parts
Numerous options for
industrialization
The PuriCoat platform is provided with
compatible internal release agents, and
offers great freedom in terms of industrial application. The surface requirements,
existing infrastructure and targeted
build rates will determine the optimal
production concept. Two main routes
are possible:
1) One-shot process - The CFRP part
manufacturing and coating steps are
carried out in a single process step, at
constant temperature.
Fig. 4: Schematic drawing of the one-shot process
2) Two-shot process - the matrix cure
and coating processes are completely
separate, allowing an optimized process
temperature for each step. This thermal
separation has a significant impact on
surface quality and cycle time.
Fig. 5: Schematic drawing of the two-shot process
Print-through can be minimized by
reducing the cure temperature, but this
leads to longer cycle times. At typical cure
temperatures of 80-90°C, cycle times of
20-30 minutes must be anticipated.
An additional issue is the limitation in
terms of complexity. Mould opening can
only create a gap in the vertical direction.
In flanges, no or at least no consistent
layer thickness can be produced. For this
reason, this process is only efficient for
2-2.5D parts.

One-shot process
The one-shot process is the classical RIM
process. One example is the SurfaceRTM technology from KraussMaffei [2],
illustrated in Figure 4.
In this concept, the part production and
coating process are carried out in the
same mould. This way, the investment
in tooling and presses can be minimized.
Part handling is also simplified.
In the one-shot process, the coating is
applied on the hot composite surface
and initially has a very good appearance.
The main limitation of this process is the
thermal shrink after demoulding. During
cooling, the resin and carbon fibre (CF)
shrink differently and trigger the fibre
print-through. These surface defects in
the cured coating cannot be fully covered.
