Definitions
- Fused Deposition Modeling employs a combination heater/extrusion head operating under computer control to extrude beads or tows of viscous thermoplastic to produce a series of stacked and fused sectional planes.
- stereo lithography a computer-controlled cold laser is used to cure photocurable epoxy held in a vat, one thin sectional layer at a time.
- An exemplary composite article manufactured in accordance with the method of the present invention is generally comprised of a freeform- fabricated core to which multiple facing skins are bonded.
- a tool path computer program is created from a three- dimensional computer-aided-design (3D-CAD) file specifying the geometry and dimensions of a composite core.
- 3D-CAD computer-aided-design
- This tool path program controls a freeform-fabrication machine that forms a solid part through the formation of successive layers of polymer, metal, or ceramic materials that are fused together.
- the 3D-CAD file specifies not only the outer shape of the core, but also specifies the geometry and dimensions of the internal reinforcing structure, which may include hex cells, box cells, trusses, tetrahedral trusses, spheres, and/or arches. Furthermore, and more importantly, the 3D-CAD file specifies channels, receivers, openings, or other integral structural elements that are formed in the core to provide enhanced bonding between the facing skins and the freeform- fabricated core.
- Figures 1A-1D are various views of an exemplary composite article 10 manufactured in accordance with the method of the present invention.
- the composite article 10 is comprised of a freeform- fabricated core 12 to which a pair of facing skins 20, 22 are bonded.
- the core 12 includes upper and lower (exterior) surface members 12a, 12b integral with and bounding an internal reinforcing structure 12c, which in this example, is comprised of an arrangement of hex cells, i.e., a honeycomb structure.
- the upper and lower surface members 12a, 12b facilitate bonding of the facing skins 20, 22 to the core 12, as further described below.
- the facing skins 20, 22 are made from a fiber- reinforced polymer material, and the bonding of the facing skins 20, 22 to the freeform- fabricated core 12 makes use of an adhesive film 30.
- a network of adhesive flow channels 14 is formed in the upper and lower surface members 12a, 12b of the core 12.
- Figure IB is a partial plan view of the core 12, illustrating the interconnected adhesive flow channels 14 in a grid pattern along the upper surface member 12a of the core 12.
- Figure 1C is a partial side view of the core 12, illustrating the generally trapezoidal cross-section of the adhesive flow channels 14 in this example.
- the facing skins 20, 22 are placed against the adhesive film 30 and the core 12. Then, the facing skins 20, 22 are cured to form a strong bond between the facing skins 20, 22 and the core 12.
- the combination of the facing skins 20, 22 and the freeform-fabricated core 12 is referred to as a "composite lay-up," and the procedure for applying the facing skins 20, 22 to the exterior surface of the core 12 is referred to as the "lay- up.”
- a vacuum is applied to the composite lay-up, effectively compressing the facing skins 20, 22 against the exterior surfaces of the freeform-fabricated core 12, and then the composite lay-up is cured. This is generally accomplished by subjecting the composite lay-up to a predetermined (higher than ambient) temperature for prescribed period of time while under vacuum pressure; however, some materials are able to cure at ambient atmospheric temperature and pressure.
- the adhesive is drawn into and fills the interconnected adhesive flow channels 14 formed in the upper and lower surface members 12a, 12b of the core 12. Accordingly, there is an enhanced bond between the facing skins 20, 22 and the freeform-fabricated core 12.
- Figures 2A-2D are various views of another exemplary composite article 110 manufactured in accordance with the method of the present invention.
- the composite article 110 is again comprised of a freeform-fabricated core 112 to which a pair of facing skins 120, 122 are bonded through use of an adhesive film 130.
- the core 112 again includes upper and lower (exterior) surface members 112a, 112b bounding an internal reinforcing structure 112c.
- an interconnected network of adhesive flow channels 114 is again formed in the upper and lower surface members 112a, 112b of the core 112, similar to those channels described above with reference to Figures IA- ID.
- generally rectangular openings 115 are also defined through the upper and lower surface members 112a, 112b of the core 112, each such opening 115 being bounded on four sides by the adhesive flow channels 114.
- each of the upper and lower surface members 112a, 112b are best described as lattices.
- Figure 2B is a partial plan view of the core 112, illustrating the interconnected adhesive flow channels 114 in a grid pattern along the upper surface member 112a of the core 112.
- Figure 2C is a partial side view of the core 112, illustrating the generally trapezoidal cross-section of the adhesive flow channels 114 in this example.
- the facing skins 120, 122 are placed against the adhesive film 130 and the core 112. Then, the facing skins 120, 122 are cured to form a strong bond between the facing skins 120, 122 and the core 112.
- the adhesive is drawn into and fills the interconnected adhesive flow channels 114 formed in the upper and lower surface members 112a, 112b of the core 112. Accordingly, there again is an enhanced bond between the facing skins 120, 122 and the freeform-fabricated core 112.
- Figures 3 A-3D are various views of another exemplary composite article 210 manufactured in accordance with the method of the present invention.
- the composite article 210 is again comprised of a freeform-fabricated core 212 to which a pair of facing skins 220, 222 are bonded through use of an adhesive film 230.
- the core 212 again includes upper and lower (exterior) surface members 212a, 212b bounding an internal reinforcing structure 212c.
- multiple receivers 214 are formed in the upper and lower surface members 212a, 212b of the core 212.
- Figure 3B is a partial plan view of the core 212, illustrating such receivers 214 along the upper surface member 212a of the core 212, and having generally circular upper and lower edges.
- Figure 3C is a partial side view of the core 212, illustrating that the receivers 214 have a generally trapezoidal cross-section.
- each receiver 214 can be characterized as being in the shape of a truncated cone.
- the facing skins 220, 222 are cured to form a strong bond between the facing skins 220, 222 and the core 212.
- the adhesive is drawn into and fills the receivers 214 formed in the upper and lower surface members 212a, 212b of the core 212. Accordingly, there again is an enhanced bond between the facing skins 220, 222 and the freeform- fabricated core 212.
- FIG. 4C is a partial side view of the core 312, illustrating that the openings 314 are generally circular or ovular, and more importantly, are positioned near the upper portion of the internal reinforcing structure where the facing skins 320 is bonded to the core 312.
- each of the walls of the cells of internal reinforcing structure 412c is designed with an enlarged edge portion 414 at the top and bottom thereof.
