<p>An apparatus (11) and method of forming a continuous tubular structure includes preselecting a liquid reactive resin forming mateial (101), particulate solid additive material (100), a porous tubular blanket (89) and an inflatable bladder member (90) disposed within the blanket. The additive particles (100) are mixed with the liquid resin forming material (101) in mixing portion (14) substantially continuously to form a uniform mixture. The tubular blanket/bladder combination is advanced through the liquid resin/additive mixture at the matrix forming portion (15), 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 preselected cross section which is then placed into a preselected final configuration.</p> |
