Abstract

A composite material comprises two sheets of flexible material secured one to each other at spaced locations to provide between the sheets a plurality of pockets and foamed material which has been expanded in situ in the pockets. A transporable sheet for forming a panel in situ may comprise two flexible sheets with pockets containing rupturable containers containing foam precursors. The sheet may be rolled-up or folded for transportation, and the containers ruptured on site. Doors or windows may be formed by slitting the panel between two lines of stitching. <IMAGE>

Description

SPECIFICATION Composite material This invention relates to composite material and, more particularly to composite materials having the beneficial qualities of rigidity, insularity and buoyancy which qualities lead to a wide range of uses of the material.
In this composite material is used material of the type formed by the chemical reaction of a plurality of chemical substances the reaction of which forms a highly-expanded material which is both stiff and of either open or closed cellular construction. Such material is herein defined as "expanded foamed material". Typical of such mateial is urea formaldehyde and expanded polystyrene.
These materials have been well known for many years and many of their qualities utilised as, for example, in wall-insulation and as packaging material. What has not been so well appreciated is that, by their action of expanding and foaming as the chemical reactions take place, they can be made to fill an otherwise flexible container to provide a rigid composite material.
The present invention is based on the realisation that by forming pockets-preferably but not essentially, linear pockets-between two sheets of flexible material and in situ filling the pockets with rigid expanded foamed material, there is provided a composite material having valuable properties utilisable in a wide range of applications.
Accordingly, the present invention provides between the sheets a plurality of pockets and expanded foamed material as herein defined which has been expanded in situ in the pockets.
One of the sheets may be a natural or synthetic cloth material and this sheet may be waterproofed.
The expanded foamed material may be urea formaldehyde or expanded polystyrene.
The composite material may be used as a structural panel and, in this case, some of the pockets should be substantially linear and extend in one direction and other of the pockets extend in a direction at an angle to said one direction. The structural panel may constitute the wall of a building, the panel then having therein a sub-panel which provides a closable opening in the wall, the sub-panel being hinged to the wall by the securing together of the two sheets at one of the spaced locations. The sheet or at least one of them may extend beyond the panel to provide an apron by which the panel can be anchored to the ground or secured to an adjacent panel.
The composite material may also be formed as a buoyancy safety apparatus as a life-belt or jacket or as a boat or raft.
The composite material, suitably dimensioned, may also be used as a surgical splint, the pockets then, desirably, extending the length of the splint.
One of the benefits of this composite material is that it, in any of its potential uses, can be supplied in a compact kit form prior to use, the kit comprising two sheets of flexible material secured one to each other at spaced locations to provide between the two sheets a plurality of pockets, a first chemical substance located in the pockets, and a second chemical substance which is reactable with the first chemical to form expanded foamed material. The first chemical substance may be impregnated into or be bonded to the face thereof facing into the pockets, at least one of the sheets. Alternatively, this first chemical substance can be located in the pockets in a rupturable container as may also the second chemical substance. Alternatively, the second chemical substance may be provided in a syringe or aerosol by which that substance can be injected into the pockets.
Embodiments of the present invention will now be described in greater detail.
In a first embodiment, the starting materials which may be supplied in a kit-comprise:- 1. Two co-extensive sheets of waterproofed canvas sewn together at parallel spaced intervals to provide between the sheets a plurality of linear parallel pockets extending substantially wholly across one direction of the sheets and further pockets, one adjacent each of opposite edges of the sheets, extending in the direction of those edges and at right angles to the plurality of pockets; all of the pockets being coated on their internal surfaces with a first chemical substance.
2. Rupturable containers, located one in each of the pockets, each containing a second chemical substance; the two chemical substances being such that they are reactable one with the other to form foamed urea formaldehyde.
The starting materials, in their kit form, provide a composite sheet which can conveniently be folded or rolled-up for transportation.
In use, the containers of the kit are ruptured to allow the two chemical substances to react one with the other. Upon this event, the two substances form the foamed urea formaldehyde which expends to fill the pockets.
Having filled the pockets, the urea formaldehyde sets to a stiff material which fills the pockets thus providing a composite-material panel which is relatively rigid, waterproof, heat-insulating and light in weight.
The thus-formed panel, if formed from suitable-dimensioned sheets, can be used as a wall for a building, the building then being erected from several such composite-material panels. For such use, the panels may variously be provided with peripheral aprons which extend beyond the panel edges and by which adjacent panels can be secured one to another or wall panels can be secured, as by pegging, to the ground.
For such constructional panels used as a wall of a building, closable door- and windowopenings may be formed simply by the sheets having been sewn together in appropriate positions by a double line of stitching. The door or window then being formed by slitting the two sheets between the double line of stitching and at right angles thereto to a parallel sewn location along the required top and bottom edges of the door or window, the door or window then being hinged to the remainder of the panel at said parallel sewn location.
Clearly, buildings constructed of this material are of considerable value as buildings in locations far removed from ready access to conventional building materials and equipment.
The buildings clearly have high heat insulating properties making them, again, particularly suited for use in extreme-temperature environments.
In an alternative embodiment, the sheets may be pre-shaped so that, when "inflated" by the foamed urea formaldehyde, there is provided a life-belt or -jacket or a life-boat or -raft.
In yet further embodiments, the sheets may be of such size and shape as to form surgical splints.
Whilst, in the above described embodiments, the chemical substances are such as to react together to form urea formaldehyde, chemical substances to form other expanded foamed material (e.g. expanded polystyrene) may be used.
