Abstract
A method of forming a continuous tubular structure includes preselecting a liquid reactive resin forming material, a particulate solid additive material, a porous tubular blanket and an inflatable bladder member disposed within the blanket. The additive particles are mixed with the liquid resin forming material substantially continuously to form a substantially uniform mixture thereof. Substantially all of the additive particles are encapsulated with the resin forming material. The tubular blanket/bladder combination is advanced through the liquid resin/additive mixture, part of which migrates through the blanket substantially uniformly to form a continuous resin matrix therein. The mixture-treated blanket is advanced along a preselected path, while the bladder therein is inflated to form a tubular structure of a preselected cross section. The structure is placed into a preselected final configuration while it is flexible and has an adhesive outer surface. Apparatus for conducting the above method.
