Abstract:
A cylinder barrel ( 1 ) for housing a piston comprises a sheet metal liner ( 2 ) and a reinforcing structure ( 10 ) located outside the sheet metal liner ( 2 ). The reinforcing structure ( 10 ) comprises a glass-fiber-reinforcing layer ( 12 ) and a carbon-fiber-reinforcing layer ( 13 ). The glass-fiber-reinforcing layer ( 12 ) comprises a plain cloth ( 20 ) made of glass fiber covering the sheet metal liner ( 2 ). The carbon-fiber-reinforcing layer ( 13 ) comprises a carbon fiber string ( 31 ) wound around the outer circumference of the glass-fiber-reinforcing layer ( 12 ) along a spiral path. According to the this construction, the reinforcing structure ( 10 ) has a high flexibility which is required for preventing cracks in the reinforcing structure ( 10 ) while maintaining a high rigidity of the entire cylinder barrel ( 1 ).
