Abstract:

The design criteria necessary for the fabrication of forms suitable to make and expand laminates of sufficient shape and size so that upon post heating the expanded laminate would shrink to the exact contour of the stump shape being fitted are discussed. Fifteen to twenty basic preforms would be necessary to fit the majority of B.E. amputees. The porous laminate system was evaluated and found to be unsatisfactory in that effective expansions of only 35 were obtainable whereas a minimum of 70 would be required to make the system at all feasible in addition the physical properties of the laminates were very poor. The overall practicality of introducing the expansible- shrinkable system into the limb industry is discussed.
