Methods for manufacturing bicycle frames

Abstract

The invention relates to a method for fabricating a monolithic bicycle frame comprising: i) creating a bicycle frame from polypropylene plastic by blow molding; ii) applying an epoxy-impregnated carbon fiber layer to the bicycle frame in combination with a binder in a mold, where the carbon fiber layer has a thickness of 1 mm to 3 mm; iii) heating the mold with steam for approximately 30 minutes, at a steam pressure of 6 to 7 bar and a temperature of 100°C to 135°C; and iv) cooling at room temperature to obtain the bicycle frame.
