N2 - An analytical model of a composite structure consisting of an F 2MC tube embedded in epoxy is used to study the impact of confining structural media on the ability of F2MC tubes to pump fluid and change stiffness. The surrounding stiff epoxy reduces the performance relative to an isolated F2MC tube, but this disadvantage can be minimized by tailoring the tube wall thickness and fiber angle. The composite can pump 250 times more fluid than a piston of the same diameter if the F2MC tube has a thick shell wall and a near-axial fiber orientation. With a moderately thick wall and low fiber angle, the closed valve axial stiffness can be increased by a factor of 2.2 relative to the open valve stiffness. The maximum pumping factor and modulus ratio, however, are 80% and 2.6% of the F 2MC tube without the surrounding epoxy.
