Abstract: A fluid actuator having a honed metallic sleeved inner liner assembled with fitted end caps. The inner liner and end caps are wound with carbon reinforced fiber filaments in both longitudinal and hoop orientations so as to withstand increased fluid pressure over traditional metallic designs. The fluid actuator of the present invention is lightweight and had an extremely stiff piston and rod assembly, which may also be fabricated from high flexural modulus composite materials so as to allow for a very stiff, lightweight, hydraulic cylinder which is particularly resistant to column buckling at long extensions and comprises an economical, non-rebuildable design.
