Has anyone played with composites? I've been considering making carbonfiber door-panels for my car for a while, idea being to use an old window panel (as the flat surface) with release-agent / pva layer on to cast a resin coat on then lamnate a layer of carbonfiber cloth onto as the colour & strengthening anyone done anything similar?
also, on my reserching (for costs of fabrics & resins) I tripped over a 'Carbon Fibre Skinning Starter Kit' www.easycomposites.co.uk/#!/starter-kits/carbon-fibre-skinning-starter-kit.html that gave me the terrible idea of covering the toombstone & a few other parts for the car not too expensive @ £39.10 +vat & carrage but not cheap.. unfortunately the kit I've linked above has a 300/1000mm piece of carbon cloth that is not wide enough to cover the toombstone in 1 section so would either need a join line or buying a larger piece of cloth (& probably more resins so not the 'starter-kit )
vid explaining tht its diy (but probably needs some practace )
although I've done plenty of fiberglass so it cannot be that hard? can it??
too many ideas & not enough time / money / concentration etc.
Hi Rich, Carbon is not so easy to use as glass, you generaly need to flood it with resin then lift the excess of with a squeege or similar. If you use epoxy resin with it the mix ratio is critical. If using polyester resin you how a bit more leeway.
I use a sheet of melamine for making flat panels you can get smooth or textured, a good clean and 6 coats of wax is sufficient, PVA will ruin the surface finish, its more use on rough surfaces to get a clean release.
Doing a flat panel in Carbon is easy, doing the tombstone would take a fair bit of practice and possibly vacuum bagging.
I am making a custom Airbox to fit a PX 500 backplate at the moment, I have roughed the pattern out of polystyrene then coated it with polyfiller to stop the resin melting it, then its sanded to shape and given a coat of gelcoat, this now needs smoothing of with 800 grit wet and dry before I take a mould of it. Once the mould is made I will decide if its going to be Carbon or Glass. I just happen to have a set of keys to a unit that has some Carbon offcuts I can have. Its a company thats linked to my normal workplace I work directly with one of its employees all the time, I live close to it so I have a set of keys in case of emergency. ( I also keep my boat there in the winter )
Hi Rich, Polyester resin would melt the tombstone so you would have to use laminating epoxy resin. It would need to have a mould taken from a tombstone. If you just covered the tombstone in carbon cloth it would make it 1mm to 2mm thicker all round which is why the thin plastic carbon look wrap is so popular.
