The method further includes pulling the plurality of fiber tows through a first chamber to wet their exterior surfaces with the polymeric resin precursor, pulling the plurality of fiber tows through a second chamber to wet the plurality of fibers within each tow, and pulling the wetted plurality of tows and fibers through a curing die to form the pultruded component.
CROSS-REFERENCE TO RELATED APPLICATIONS The present invention is related to U.S. patent application Ser. No. 11/287,143 titled �System For Producing Pultruded Components�; U.S. patent application Ser. No. 11/287,142 titled �Pultruded Component�; and U.S. patent application Ser. No. 11/287,141 titled �Resin for Composite Structures�, each of which were filed on the same date as the present application.
SUMMARY An exemplary embodiment of the invention relates to a method for producing a pultruded component that includes providing a plurality of fiber tows each formed of a plurality of fibers. The method also includes providing a first chamber and a second chamber for wetting the plurality of fiber tows with a polymeric resin precursor. The method further includes pulling the plurality of fiber tows through a first chamber to wet their exterior surfaces with the polymeric resin precursor, pulling the plurality of fiber tows through a second chamber to wet the plurality of fibers within each tow, and pulling the wetted plurality of tows and fibers through a curing die to form the pultruded component.
Q = A ⁢ ⁢ K ⁢ Δ ⁢ ⁢ h L where Q is the volumetric flow rate, A is the flow area perpendicular to L, K is the hydraulic conductivity, and Δh/L is the change in hydraulic head over the path length. Although Darcy's Law can be said to take capillary action into account via the K (hydraulic conductivity) term, in practical terms different values must be used as the scale changes and the relative importance of the forces involved changes, making it less effective at describing the entire wetting process.
L 2 = γ ⁢ ⁢ D ⁢ ⁢ t 4 ⁢ ⁢ η where t is the time for a liquid of viscosity η and surface tension γ to penetrate a distance L into a fully wettable, porous material whose average pore diameter is D.
