Abstract
A device (10, 40, 50, 60) and a related method for selectively applying pressure to a fiber impregnated resin, where the device includes a thermally expansive material having a body (12) which extends in an axial direction from an upper terminal surface (14) to an opposite lower terminal surface (16), a first retaining member (18) affixed to one of the upper terminal surface and the lower terminal surface, wherein the first retaining member is configured to limit expansion of the thermally expansive material in a direction substantially perpendicular to the axial direction when the thermally expansive material is subjected to an increase in temperature.
