Abstract:
A centralizer can be produced from a process comprising forming a plurality of composite bow spring from a fiber and a resin, curing the composite bow springs in a desired shape to form a plurality of cured bow springs, disposing a first portion of a resin-wetted fiber about a cylindrical mandrel to form a plurality of collars, disposing the plurality of cured bow springs onto the mandrel with the bow spring ends in contact with the first portion of resin-wetted fiber, disposing a second portion of the resin-wetted fiber about the cylindrical mandrel, curing the collars to form a cured centralizer, and pressing the mandrel out of the cured centralizer.
