Definitions
- the present invention relates to a composite sheet, in particular a composite sheet which has a variety of uses such as a building material, as packaging material, as a panel or the like.
- the present invention also relates to a method of producing a composite sheet.
- flute board such as a fluted sheet of suitable plastics material, commonly referred to as "flute board”.
- This material is constructed with two spaced webs interconnected by a plurality of substantially parallel, spaced walls defining parallel channels or flutes.
- the principals of the invention can be applied to any sheet or board which has flutes or channels located therein.
- flute board has been used for various applications, for example, for signage, boxes or storage containers.
- flute board has inherent disadvantages associated with its use as will be explained hereinunder.
- a planer sheet of flute board Due to the physical characteristics of a planer sheet of flute board, when a bending movement is applied to the board along the length of a channel, one or more of the channels of the sheet of flute board is placed under pressure and the sheet of material may fold along the length of the channel under pressure.
- flute board may not maintain its normal rigidity when placed under bending forces.
- many other known boards or sheets are also considered relatively weak and vulnerable to bending or collapsing when placed under appropriate bending forces.
- such containers have inherent disadvantages in that the flute board may not maintain its strength or rigidity when placed under undue load.
- Flute board is also widely used in signage, such as for pointer boards for real estate advertising.
- flute board When such signage is placed under load, such as from weather conditions or from vandalism, the sign is liable to fold along a channel line and be damaged.
- a further disadvantage of flute board is that it is not generally constructed to withstand exposure to high temperatures. Still further, flute board does not have any acoustical, buoyancy or impact resistance properties.
- flute board is a relatively inexpensive material to manufacture and therefore the end cost to the consumer is relatively small.
- flute board also have advantages. Traditionally flute board is made from a synthetic plastics material such as polypropylene, thus producing a lightweight sheet of material which is easy to handle. Therefore, when considering transport costs, the transportation of flute board is relatively inexpensive. The many other advantages of flute board include its ability to be easily cut with a knife or saw.
- the present invention provides a composite sheet which obviates some of the problems of traditional sheets, in particular flute board.
- a composite sheet for use as for example, a building or construction material, packaging or the like, the composite sheet comprising: a sheet of fluted material having a series of substantially parallel channels defined by at least one surface and a plurality of spaced walls; at least some of said channels being impregnated with a filler material.
- the filler material is an expanding material, such as an expanding synthetic plastics foam material.
- the sheet of fluted material is flute board, made from, for example a synthetic plastics material such as a polyethylene or a polypropylene.
- the filler material may be a foam, such as a polyurethane foam.
- a method of producing a composite sheet comprising forming a sheet of fluted material with a plurality of substantially parallel channels defined by at least one surface and a plurality of spaced walls, filling at least some of the channels with a filler material and allowing the filler material to set within said at least some of the channels.
- the filler material is an expandable material such as an expanding synthetic plastics foam material, such as foamed polyurethane.
- the method of impregnation of the channels is dependent upon many factors, including the size of the channels.
- the appropriate method of impregnation must be chosen to ensure that the size of the cavity of the channel does not hinder distribution of the filler material, which, if incorrectly carried out. may cause back expansion toward the filling end of the channel, thus blocking the channel against the further flow of the filler material.
- the fluted material may be heated prior to impregnation. Heating of the material assists in lowering the viscosity of the filler material as it moves through the channels, therefore aiding quick and even distribution.
- the flute sheet may be positioned at an angle during impregnation of the filler material to assist in downward distribution of the material through the channels.
- the strength of the fluted sheet may be increased by inserting one or more substantially rigid elongated members, such as wires or rods through the channels prior to impregnation of the filler material.
- the wires or rods are encapsulated by the filler material and act as reinforcing for the sheet. It has been found that a particular advantage of the sheet of the invention is that the impregnated sheet may be welded.
- Impregnation of, for example, an expanding material able to withstand high temperatures will enable the impregnated sheet to be welded without damaging the flute structure.
- a sheet of the invention has all channels thereof impregnated with an expandable material.
- only predetermined or selected channels are impregnated with the expanding material. In carrying out the impregnation, should a channel be incorrectly impregnated, it is possible to cut a surface of the channel and bend the channel along its length to release the incorrectly located filler material.
- Figure 1 is a diagrammatic end view of a composite sheet according to one embodiment of the invention
- Figure 2 is a diagrammatic isometric view of the composite sheet of
- FIG. 3 is a diagrammatic view of a further embodiment of the invention.
- the features of the invention are more readily understood we shall hereinunder describe the features of the invention.
- the sheet 12 comprises an upper surface 14 spaced from and substantially parallel to a lower surface 16.
- the upper and lower surfaces 14 and 16 are separated by a plurality of substantially parallel walls 17 which define with the upper and lower surfaces, channels or flutes 18.
- the material is generally formed of a synthetic plastics material such as polyethylene or polypropylene, but may be made of any other suitable material including other synthetic plastics material, cardboard or paperboard or the like.
- the channels 18 are filled with a filler material 19 which, in this embodiment, is a synthetic plastics foam material comprising foam polyurethane.
- a filler material 19 which, in this embodiment, is a synthetic plastics foam material comprising foam polyurethane.
- the type of polyurethane foam may be AU 270.
- the composite sheet so formed has substantially increased rigidity and strength due to the structure of the filler material which is able to maintain the spacing between the upper and lower surfaces 14 and 16 and greatly resist bending forces applied to the sheet 12. It will be understood that the filler material 19 substantially fills the channels 18. Once the filler material 19 has foamed and set in each channel, it is referred to as a channel filler.
- a sheet of fluteboard having channels 10mm square and an overall dimension of approximately 2000 to 3000mm by 1000 to 1500mm is used.
- the length is 2440mm and width 1220mm.
- the fluteboard is placed on a slated table which allows a direct heat from infra-red lamps to substantially evenly heat the sheet 12.
- the sheet 12 may be heated by an indirect heat, such as in a heat controlled environment.
- a heat controlled container or vessel In the former method the infra-red lamps are supported above and below the table to heat the respective surfaces 14 and 16 and the walls 17.
- the sheet 12 is positioned at an angle between 30° and 40°, but preferably at 35° to the vertical and the sheet 12 is heated as hereinbefore described to a temperature of between 45° and 50°C.
- the polyurethane filler material 19 is preheated to approximately 35 °C prior to introduction into the elevated ends of the channels 18.
- the filler material 19 is introduced into channels 18 and allowed to run down the channels. Once the filler material 19 reaches approximately the middle of the channel 18 the filler material 19 commences to foam, thereby expanding to evenly and substantially fill the channel 18.
- the angle of the sheet 12 may be substantially vertical in which case prior to introducing the filler material at upper ends of the channels 18, the lower ends of the channels are blocked or capped in any suitable manner. On introducing the filler material 19 to the channels 18 the filler material 19 flows to the lower end of the channel where it foams and rises upward to substantially evenly fill the channel 18.
- the angle of the sheet 12 may be substantially horizontal in which case the filler material 19 is injected into the channels 18 via at least one aperture extending through either or both surfaces 12, 14.
- the apertures are located substantially at the middle of the channel.
- the filler material 19 can be introduced at one end of channel 18 and thereafter capping of this end of the channels thereby forcing the foam to expand torward the other open end of the channel 18.
- one or more of the channel fillers may be removed from relevant channels by slitting appropriate upper or lower surfaces 14 or 16 and bending the sheet 12 enabling the channel filler 21 to be removed. This may be required if it is necessary to bend the composite sheet at a relatively sharp angle. Otherwise, the sheet may be compressed along the line of a desired bend to facilitate bending thereof.
- FIG. 3 there is illustrated a composite sheet made in accordance with the present invention in which only every second channel 18 is filled with filler material 19. This arrangement is appropriate where the sheet is to be bent around a relatively sharp curve.
- a sheet made in accordance with the embodiment shown in Figure 1 may be curved by heating the composite sheet with hot air. With such heating, the material of the invention may be formed into complicated curved shapes, such as to form the curved sides of a boat or the like.
- a plurality of panels in accordance with the present invention may be welded or otherwise laminated together to form multiple composite panels of increased strength and durability.
- the composite material of the invention may be formed using a corrugated board, such as corrugated cardboard, or similar board material formed of synthetic plastics material. The use of "flute board" is preferred only.
