Abstract
High structural strength sandwich panel 12 comprising a prefabricated core, which consists of a lattice 2 filled with a filler 7, and skins 9 bonded to the core. The lattice may be a one-piece grating or a plurality of crisscrossed strips, both being rigid and made from fibre reinforced polymers. The filler may comprise polymeric foam or an aerated cement based product. A method of applying the skins is also claimed which may comprise the steps of covering each face with a prepared wet resin and pressing fibre reinforcements into the wet resin to achieve full impregnation. The wet resin may be epoxy, polyester, phenolic, vinyl ester, acrylic or other suitable polymeric resins. The fibre reinforcement may be glass, carbon, polymer and may take the form of chopped strands, woven roving, multi-axial or similar mats.
Description
HIGH STRUCTURAL STRENGTH SANDWICH PANEL
This invention relates to a high structural strength sandwich panel, a product composed of two sheets of rigid material bonded to either side of a prefabricated core. In addition, the invention addresses the method of assembly which provides full adhesion between the said sheets and core.
Sandwich panels normally consist of sheets, or skins', made from a variety of materials -typically metals, plastics, timber, minerals, -which are bonded to core materials such as foam, timber, honeycomb, polymers or similar and are used in a wide range of applications including construction, industrial, mass transit, aerospace and many similar industries. These panels are widely accepted for their positive strength to weight ratios and are particularly suitable for audio and thermal insulation systems. The majority of such panels are used in vertical and overhead applications such as walls, partitions, cladding, ceilings and similar where there are limited structural demands. Such panels are rarely used for base levels such as floors, decks or thoroughfares where traffic -pedestrian, vehicular or otherwise -is common. This is mainly due to the relatively low compressive strength of the light weight core -usually foam -and, in many cases, its friability. A further problem with conventional sandwich panels relates to the adhesion between skin and core. Unless total surface adhesion is achieved voids, caused by air entrapment or a diaphragm', can occur and severely reduce a panels' strength.
This invention seeks to overcome such deficiencies by combining methods and materials that will result in relatively lOw cost, easy to manufacture, high structural strength sandwich panels suitable for base levels. In particular, this invention seeks to replace metallic manhole, drain, sewer, trench and road covers where theft of such versions for raw material scrap value costs relevant authorities world wide large sums in replacement and compensation claims due to resultant property and personal damage. By combining a unique prefabricated core with an assembly method to ensure full adhesion to the skins results in a sandwich panel with high flexural, tensile and compressive strengths. These aspects will now be described as follows and with reference to the accompanying drawings in which; Figure 1 shows an isometric view of the sandwich panel with a section of top skin removed to reveal the core structure containing the lattice and filler.
Figure 2 shows a side elevation of the lattice made from strips of solid material with embossed vertical wall faces, Figure 3 shows the resin and fibre application.
The Core I -this contains two main elements; i) A lattice 2. Lattice structures are manufactured using long established methods involving notching and crisscrossing strips of solid material. In this invention such strips would have embossed vertical wall faces 3 which would act as a key to hold the filler in position. One-piece cast gratings, whilst having a similar shape and material content as lattice structures, have superior strength to equivalent lattice structures and can alternatively be used in this invention for the same purpose. For clarity, both crisscrossed strip and grating versions will be referred to as lattice. Lattices are available in metallic and non-metallic materials, the latter being the more acceptable choice for low weight and low residual scrap value. The most suitable material in this category are fibre reinforced polymers -commonly referred to as GRP -and, as such, can be made available in a variety of sizes where wall thickness 4, height 5, and pitch 6 are chosen to define physical performance requirements and thus suit the particular end application.
ii) The Filler 7. This part of the core has to completely fill every cavity of the lattice and can be any of a wide variety of polymeric foams, most notably polyurethane, or aerated cement based products such as foam concrete.
Methods exist to apply such fillers manually or mechanically.
All lattice cavities are filled to (naximum capacity with the filler 7 so that flat, level surfaces 8 remain. It is to these surfaces 8 that the skins 9 are bonded and it can be seen that the filler 7 need only provide a platform for the skin 9 and thus the filler 7 requires having good tensile strength to prevent delaminating of the finished panel. This is an essential feature of this invention.
The Skins 9.
These can be produced from a wide range of materials including, but not restricted to, metals, timber, minerals and/or plastics and all can be applied using adhesives and conventional techniques such as pressing, vacuum bagging or similar. However, to ensure uniformity and no bonding voids, this invention uses curing wet resins 10 and reinforcements II to manufacture the skin 9 direct on to the core thus using the wet resin as an adhesive. The preferred resin 10 is epoxy due to its adhesive quality, high strength and low shrinkage although other wet resins such as, but not limited to, polyester, phenolic, vinyl ester and acrylic can be used. Compatibility between the resin and the core materials has to be verified initially as some foams and resins are incompatible. The method of skin 9 manufacture used in this invention is known in the composites industry as wet lay-up' and can be applied manually or mechanically using a variety of tried and tested processes. The filled lattice core us laid horizontally on a flat surface which may be a table, bench, conveyor or similar. A predetermined quantity of prepared resin 10 is applied to the full upper surface of the core I. Reinforcements II including, but not limited to, glass, carbon and polymer, are supplied in various forms including, but not limited to, chopped strands, wovens, co-axials, multi-axials and similar mat products. A chosen amount are placed on the resin 10 coated core I and are pressed into the resin 10 until full impregnation of the reinforcement 11 is achieved. This process, which can be manual or mechanised, is repeated until the desired laminate thickness and strength are obtained at which time the finish coating is applied. This may consist of textured, smooth, non-slip, painted or similar surfaces as required for which many methods exist. When the skin is cured, that is, hardened, the core I is reversed and the skin application process repeated on the opposite face. /
