A structural member that contains a solid lineal profile (516, 600, 700) that is formed from a plurality of consolidated ribbons (12). Each of the ribbons includes unidirectionally aligned continuous fibers embedded within a thermoplastic polymer matrix. The continuous fiber ribbons (12) are laminated together during pultrusion to form an integral solid profile (516, 600, 700) having very high tensile strength properties.

1. A structural member comprising a solid lineal profile, wherein the solid lineal profile contains a first component formed from a consolidated laminate of individual ribbons, wherein each ribbon of the laminate contains a plurality of continuous fibers that are substantially oriented in a longitudinal direction and a resinous matrix that contains one or more thermoplastic polymers and within which the continuous fibers are embedded, the continuous fibers constituting from about 40 wt. % to about 90 wt. % of the ribbon and the thermoplastic polymers constituting from about 10 wt. % to about 60 wt. % of the ribbon, each ribbon of the laminate formed from a consolidated plurality of resinous matrix impregnated fiber rovings, wherein the flexural modulus of the profile is about 10 Gigapascals or more. 2. The structural member of claim 1, wherein the continuous fibers include glass fibers, carbon fibers, or a combination of glass and carbon fibers. 3. The structural member of claim 1, wherein the thermoplastic polymers include a polyolefin, polyether ketone, polyetherimide, polyarylene ketone, liquid crystal polymer, polyarylene sulfide, fluoropolymer, polyacetal, polyurethane, polycarbonate, styrenic polymer, polyester, polyamide, or a combination thereof. 4. The structural member of claim 1, wherein the continuous fibers constitute from about 50 wt. % to about 85 wt. % of the ribbon. 5. The structural member of claim 1, wherein the ribbon has a void fraction of about 2% or less. 6. The structural member of claim 1, wherein the laminate is formed from 10 to 30 individual ribbons. 7. The structural member of claim 1, wherein the profile has a flexural modulus of from about 30 to about 60 Gigapascals. 8. The structural member of claim 1, wherein the profile has a flexural strength of about 250 Megapascals or more. 9. The structural member of claim 1, wherein the profile has a flexural strength of from about 300 to about 2,000 Megapascals. 10. The structural member of claim 1, wherein the profile has a void fraction of about 2% or less. 11. The structural member of claim 1, wherein the profile comprises a second component formed from a consolidated laminate of individual ribbons, wherein each ribbon of the laminate contains a plurality of continuous fibers that are substantially oriented in a longitudinal direction and a resinous matrix that contains one or more thermoplastic polymers and within which the continuous fibers are embedded, and wherein the continuous fibers of the second component have a greater tensile strength in the longitudinal direction than the continuous fibers of the first component. 12. The structural member of claim 11, wherein the ratio of the tensile strength of the continuous fibers of the second component to the tensile strength of the continuous fibers of the first component, in the longitudinal direction, is from about 1.2 to about 2.5. 13. The structural member of claim 11, wherein the second component is distributed generally symmetrically about a cross-sectional center of the profile. 14. The structural member of claim 11, wherein the continuous fibers of the second component include carbon fibers and the continuous fibers of the first component include glass fibers.
