    •  DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
  • The following description of the embodiment(s) is merely exemplary (illustrative) in nature and is in no way intended to limit the invention, its application, or uses.
  • The figures illustrate an exemplary embodiment of an anti-intrusion beam 10 used in a vehicle door assembly such as an automotive side door assembly 12. The anti-intrusion beam 10 may be formed of a composite material which may include a fiber reinforcement 14. The fiber reinforcement 14 may be constructed and arranged to increase energy absorption, increase stiffness, and decrease weight in the anti-intrusion beam 10 as compared to a conventional anti-intrusion beam made of steel by a stamping metalworking process.
  • The automotive side door assembly 12 may be a driver-side, passenger-side, rear door, or another door of an automobile. In one exemplary embodiment illustrated by FIG. 1, the automotive side door assembly 12 may include an outer panel 16 and an inner panel 18. In select embodiments, the outer panel 16, the inner panel 18, or both, may include magnesium and/or aluminum, or an alloy thereof. The inner panel 18 may include a hinge wall 20 and a latch (not shown). In one embodiment, the anti-intrusion beam 10 may be made as a separate component than the outer and inner panels 16, 18 and may be connected to the inner panel via adhesive bonding. In another embodiment, the anti-intrusion beam 10 may be made as an integral part of the inner panel 16, and may be molded integrally with the inner panel.
  • Referring to FIGS. 1-3, the anti-intrusion beam 10 may reinforce the automotive side door assembly 12 and may help protect occupants of the automobile against side impacts. The anti-intrusion beam 10 may have a body 21 with lengthwise dimension L and a widthwise dimension W. The anti-intrusion beam 10 may have a first flange 22 extending in an inboard direction to a first free end 24, and may have a second flange 26 extending in an inboard direction to a second free end 28. In cross-sectional profile, the anti-intrusion beam 10 may have a corrugated or double-hat shape. The shape may comprise a first and second ridge 30, 32 on an inboard side 34, and may comprise a third ridge 36 and a first and second channel 38, 40 on an outboard side 42.
  • In select embodiments, the anti-intrusion beam 10 may be formed of the composite material which may include the fiber reinforcement 14. The composite material may also include an epoxy resin, a polyester resin, a vinyl ester resin, or a polyurethane resin. Referring to FIG. 4, the fiber reinforcement 14 may include multiple fibers 44 such as glass or carbon fibers. In one embodiment the fibers 44 may include an equal number of fibers in a weft and warp plain weave, and may include multiple weft fibers 46 and multiple warp fibers 48 interweaved under and over each other. The weft and warp fibers 46, 48 may be oriented about 90° with respect to each other, and may be oriented to define an angle ⊖ with respect to the lengthwise dimension L. The angle ⊖ may range between about 35° and 55°, and in one embodiment may be about 45°. Angle values outside of that range may, in some cases, decrease energy absorption.
  • The fiber reinforcement 14 may include two to six separate layers of fabric pieces or plies located between the inboard and outboard sides 34, 42. In one embodiment, the fiber reinforcement 14 may include three separate layers of fabric pieces. Each fabric piece includes its own fibers 44 which may be oriented at about 90° with respect to each other, and between about 35° and 55°, or about 45° with respect to the lengthwise dimension L. Each fabric piece may be a 24 oz/yard2 piece, a 12 oz/yard2, or another suitable piece.
  • In the case of glass fibers, the anti-intrusion beam 10 may have a thickness ranging between about 1.5 and 2.0 mm, and in the case of carbon fibers, the thickness may be about 1.0 to 1.8 mm. Of course other thickness values are possible. The thicker the anti-intrusion beam 10, the more energy the anti-intrusion beam 10 can absorb and the stiffer the anti-intrusion beam. Also, the deeper the channels 38, 40 and more pronounced the ridges 30, 32, 36, the stiffer the anti-intrusion beam 10.
  • In one embodiment, the anti-intrusion beam 10 may be manufactured by a liquid composite molding process. The process may involve injecting liquid resin into a dry fiber preform, and may include resin transfer molding and vacuum-assisted resin transfer molding. In other manufacturing processes, fabric pieces may be pre-impregnated with resin and then compression molded or cured in an autoclave.
  • FIG. 5 shows an exemplary stress-strain graph for an exemplary tensile bar representing one embodiment of the anti-intrusion beam 10. All experiments may not necessarily yield these exact results. The tensile bar had three fabric pieces of 24 oz/yard2 of fiber reinforcement with glass fibers oriented at 450 with respect to the lengthwise dimension. The thickness of tensile bar was about 1.8 mm.
