Abstract: A pultruded composite component includes a matrix material comprising a thermosetting polyurethane resin, and fibers provided within the resin matrix. All of the fibers within the resin matrix are oriented in substantially a single direction and the matrix material has an elongation-to-failure that exceeds that of the fibers.

Abstract: A resin precursor composition includes an isocyanate component, a first polyol having a molecular weight of between approximately 600 and 800 and an OH index of between approximately 200 and 300 mgOH/g, and a second polyol having a molecular weight of between approximately 100 and 300 and an OH index of between approximately 800 and 1,200 mgOH/g.

Abstract: A resin precursor composition for use in the production of composite components includes an isocyanate component comprising a material selected from the group consisting of diphenylmethane diisocyanate, a polymeric isomer of diphenylmethane diisocyanate, and combinations thereof. The resin precursor composition also includes at least one polyether polyol having a functionality of three in an amount such that the ratio of the isocyanate component to the at least one polyol is between approximately 80% and 115% of stoichiometric. The resin precursor composition also includes a mold release material and a filler material.

Abstract: A system for producing a pultruded component includes a fixture for providing fibrous reinforcements, a system for providing a polymeric resin, and an impregnation die for coating the fibrous reinforcements with the polymeric resin precursor. The impregnation die includes a first chamber and a second chamber. The fibrous reinforcements include fiber tows made of a plurality of fibers. The system also includes a curing die for forming the pultruded component. The first chamber of the impregnation die is configured for coating exterior surfaces of the fiber tows with the polymeric resin precursor. The second chamber of the impregnation die is configured for coating the plurality of fibers within the fiber tows with the polymeric resin precursor.

Abstract: A method for producing a pultruded component 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.
