  • Corrugated members alone or in combination with facing sheets to provide panels or corrugated sheets, when used in an arcuate or contoured configuration dispose the corrugations axially with respect to the are rather than circumferentially. Axial extension has provided ease of forming. This is particularly true when the corrugated member is formed of generally rigid materials such as of reinforced plastics or metals.
  • corrugations may be extended generally circumferentially with respect to flow through an air passage.
  • Another object is to provide such a member capable of being joined with similar mating members to provide a core useful with facing sheets in production of a panel unstressed prior to use.
  • FIG. 1 is an isometric sectional view of an arcuate member of the present invention
  • FIG. 2 is a fragmentary axial view of the member of FIG. 1 in the direction of II II;
  • FIG. 3 is a fragmentary cross-sectional view of the member of FIG. 1 assembled into an arcuate panel
  • FIG. 4 is an isometric partially sectional fragmentary view of two corrugated members bonded together
  • FIG. 5 is a cross-sectional fragmentary view of the member of FIG. 4 when assembled into a panel.
  • FIG. 6 is an isometric fragmentary view of the member of FIG. 1 assembled with a facing sheet to provide an arcuate article.
  • the present invention in one form provides a corrugated arcuate member having a plurality of substantially rigid corrugations disposed generally circumferentially of the arcuate member.
  • the corrugations are defined by alternating radially inner and outer portions which abut or are continuous one with the other to define the corrugations.
  • Each outer portion includes a plurality of spaced apart generally transverse slots disposed along an outer portion and discontinuous between consecutive outer portions. Holding the member in arcuate shape is an arc-holding means secured with a corrugation.
  • the present invention provides a corrugated arcuate article of two of such arcuate members secured one to the other at their inner portions to define between their outer portions a plurality of generally circumferentially disposed chambers.
  • corrugated arcuate member or arcuate article or combinations built to desired thicknesses in another form of the present invention, can be included in panels through the assistance of facing sheets secured with the corrugations.
  • the cross-section of the corrugations can be sinusoidal, a series of similarly directed hemispheres, etc. rather than the more angularly shaped configuration shown in the drawing.
  • the corrugated arcuate member shown generally at 10 in FIGS. 1 and 2, includes outer portion 12 and inner portion 14 abutting one to the other and drawn as a continuous member. As shown in FIG. 2, the corrugation is arcuate generally circumferentially of the arcuate member.
  • outer portion 12 Included in outer portion 12 are a plurality of spaced apart slots 16 disposed along the outer portion 12 generally transverse to the circumferential disposition of the corrugations. Slots 16 are discontinuous between consecutive outer portions to provide structural integrity. However, as shown in the drawing, the slots can extend partially into the inner portion depending upon the flexibility desired in the arcuate member during manufacture. In addition, if desired, similar slots can be included through the inner portion, such as alternating with those of the outer portion to maintain structural integrity of the member.
  • an arc-holding means secured with a corrugation.
  • arc-holding means can be a tape 18 such as of a thermosetting plastic bonded to a corrugation, preferably across consecutive slots of at least a part of the outer portion.
  • an areholding funcu'on can be performed by a facing sheet or member 20, in FIG. 6, with which the corrugation is assembled in the manufacture of a panel.
  • FIG. 3 A fragmentary cross-section of a panel which can be made from the corrugated arcuate member of the present invention is shown in FIG. 3.
  • the arcuate member 10 is sandwiched between facing members 20, such as in sheet form, to provide such a panel.
  • facing members 20 such as in sheet form
  • Facing sheets or members 20 can be applied to provide a lightweight arcuate panel of desired thickness.
  • the areholding means or tape 18 can be applied for multiple functions. It can operate not only to hold the corrugated arcuate member 10 in arcuate shape, but also toact as a deterrent to axial air flow through the member, the corrugations of which are disposed generally circumferentially. of the direction of .flow of air through the engine.
  • Such an arrangement is shown in the fragmentary isometric view of FIG. 4 and the fragmentary sectional view of FIG. 5.
  • such a tape can be applied to the inside of corrugations and can be used to bond together two arcuate members at their inner portions as particularly shown at 22 in FIG. 5.
  • the two corrugated arcuate members When assembled as shown in FIGS. 4, S and 6, the two corrugated arcuate members define chambers disposed generally circumferentially of the arcuate member.
  • the slots 16a shown in FIGS. 4 and 6, tend to widen at their radially outward portion whereas slots 16b tend to narrow at their radially inward portion.
  • the provision of such generally transverse slots either in the single corrugated arcuate member configuration shown in FIGS. 1 2 and 3, or in the multiple configuration shown in FIGS. 4, 5 and 6, provides improved formability during manufacture.
  • two corrugated arcuate members of the type shown in FIG. 1 were prepared from epoxy resin impregnated glass cloth to produce a corrugated arcuate member of about one-half inch in depth.
  • the slots were about 0.05 inch wide, spaced about 0.3 inch one from the other transversely through the outer portion 12.
  • thermosetting plastic in the form of a modified epoxy film adhesive or tape 18 was located at 22 between inner portions 14 positioned as shown in FIG. 5.
  • the members thus held were then heated at about 250 F. to cure the adhesive and to bond the members together at 22, thus creating chambers 24.
  • such an adhesive can be applied at 22 between inner portions 14 as shown in FIG. at the same time as it is. applied across consecutive slots in the manufacture of the arcuate corrugated member. In such a case, a singletire corrugation. Nevertheless, such slots are maintained as discontinuous between consecutive outer portions to provide structural stability.
  • An additional advantage of the present invention particularly useful in the manufacture of air passage panels such as for jet engines, its three dimensional forming capability.
  • a member can be contoured using the present invention not only circumferentially'of such a duct but also radially and axially in the same panel.
  • a corrugated arcuate article comprising: two'arcuate members secured one with the other at their inner portions to define therebetween a plurality of substantially diamond shaped circumferentiallydisposed chambers, each chamber including two pairs of opposed lateral faces; each member comprising:
  • each outer portion including a plurality of spaced apart generally transverse slots disposed along the outer portion and discontinuous between consecutive outer portions;
  • the article including. an arc-holding thermosetting plastic tape secured with the lateral faces of one pair of the two pairs of opposed lateral faces of alternating chambers across portions of consecutive slots in the faces.
