Plastic Panels
I've been approached about building some FRP Moulds for Speedway cars over here but I was thinking the class that approached me would be better off with plastic panels. I've seen the finished products before and i was wondering if anyone could shed some light on how they are made...............trikes

Vacuum forming is probably the cheapest way to shape a small quantity of panels.

vacuum forming can be used for thermo plastics and thermosetting palstics! One form can be heated and moulded again the other cant but forget which way round it is...

There is a huge range of thermoplastics, some more suitable than others for vacuum forming...polycarbonate (eg Lexan) being the toughest, but it absorbs water and is difficult to mould. Thermosetting plastics such as polyester resin as used in laying up laminates to my knowledge cannot be vacuum moulded. They can be layed up and a vacuum bag used to consolidate the laminate but that is not the same thing.

Most plastics, Lexan including, are too heavy, flexible, and cannot hold the shape under continuous stress and heat.
I wonder if someones knows some thermosets that are not brittle. I double that they exist. I discovered alumalite and econolite panels, which are a thin aluminum sandwich with a plastic core, but they are only good if you need something that is reasonably strong, like the floor or the splitter, else they are too heavy as well. The prices of carbon fiber panels are kinda high. Plywood is still a good option for some projects!

ABS is one plastic commonly used for automotive panels:
