ABSTRACT:
A method of manufacturing a piston for transferring an output force to a member in responsive 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 inpregnated with a thermoset resin and cured to define a unitary solid structure. Thereafter a cone and collar, throughwhich an output force is suppled to member, is attached to the second en dand the unitary structure inserted in the bore.
