Apparatus Impregnates Weak FibersLow-cost apparatus developed for use in conventional drum winding machine to impregnate fibrous materials having very low tensile strengths. Fiber fitted onto freely-spinning unwinding creel. Unwinds from creel between two tension bars onto guide spools, aligns fiber so properly enters sealed reservoir of resin. Stainless-steel metering die at entrance to reservoir aligns fiber and seals reservoir. Beneficial results obtained by use of reservoir made of polyethylene. Composite material made from resin matrices reinforced by fibers have great potential for solving challenging and often critical problems in design of spacecraft, space structures, and terrestrial structures.
