A group of engineering students at National University of
Singapore has built a full-size two-seater electric car from the ground up - a
feat usually performed by full-fledged vehicle manufacturers.
They built a hybrid steel-carbon fibre spaceframe by welding
steel beams together and forming the lightweight and ultra-rigid material
themselves.
The carbon fibre sheets are cured in a special oven. With a
layer of foam sandwiched between two sheets, the carbon- fibre panels are bolted
onto the steel skeleton to form the passenger cell.
