making a board out of plastic?

[$heepy]

i was talking to my tech teacher the other day about a project of making a plastic surfboard.

i was thinking of making one out of solid plastic, because weight wont really be a problem and we dont have the tools to form it and have it hollow in the inside.

i asked him what he thought would be the best and he thought the stuff that r/c car bodies are made out of. poly carbonate or some thing like that.
where as at first i was thinking a big slab of acrylic or a lot of sheets of acrylic laminated together.

i was thinking of using routers, and sanders to shape it and then have the fins on the bottom rebated and glued in.

it will be a board just to take down for my mates and my sister that wanna paddle round and muck about when its calm.

am i crazy or is it feasible? what sort of shape should i be looking at doing it, size, and what prices are the plastics you would recommend.

fibre glass is made of glass amazingly;

and isn't a plastic.

Other plastics you might want to consider are;
- expanded polystyrene
- expanded polypropylene
- expanded polyethylene
- expanded polyurethane
- polyester resin
- epoxy resin
- ....

I suspect unless Sheepy's teacher is cluey the board will be poly-unsaturated.
There were some boards way back that were like the very cheap kick boards; two shaped plastic shells welded together they failed within the first hour of any sort of real surf even kiddies corner type shore breaks.
