ABSTRACT:
A method of manufacturing a piston for transferring an output force to another member in response to pressurized fluid being communicated to a bore in a housing. The piston has a cylinder body made of a plurality of triaxial braided layers of carbon fibers which are placed on a mandrel with spacers located between the layers to form an annular projection of a first end and a taper of a second end. The carbon fibers are impregnated with a thermoset resin and cured to define a unitary solid structure. A cone and collar is attached to the second end to form a unitary piston. The piston is inserted in the bore and moved by the pressurized fluid to provide the output force for the other member.
