Abstract
Aluminium clad composite tubes (figure 1), which comprise a hollow section bicomposite core 5 with outer 1 and inner 4 sheaths of thin gauge seamless aluminium or copper cladding reinforced by a laminate 5 between the sheaths 1, 4. They offer high strength/aluminium weight ratio, and includes low voltage current carrying capability. They provide valuable outlets for recycling waste materials into useful value added products. The reinforcing material may be made from wood, plant, natural or synthetic materials. These may be incorporated in fibre, sheet, woven or solid form. <IMAGE>
Description
NON-FERROUS METAL CLAD THREE PART COMPOSITE TUBE E:truded aluminium and copper circular and rectangular section tubes are etensively used as structural building and construction materials but tend to be limited to light structural applications. where high surface finish , corrosion resistance and light weight(in aluminium's case) are the principal attributes required. In thin walled gauges. where they could be price competitive with other materials. lower structural strength and poor impact resistance, prevent their wider application.
Sheet manufacturers have exploited aluminium's quality attributes by producing re-inforced sandwich laminates in which low cost. lightweight. cheap materials. such as foamed plastic and chipboard are luminated on both sides with sheet aluminium.
The design of a composite, aluminium or copper clad. tubular product. which can use thin aluminium or copper cladding it the addition of a re-inforcing laminate. is seen as a method ot producing aluminium or cop per tubing with the equivalent strength of thick walled tubing at a much lower cost.
The invention comprises a range of threes-part. composite.
aluminium or copper clad tubular products. all having an inner and outer cladding of thin gauge aluminium or copper. with a thin re-inforcing laminate. sandwiched between the two aluminium or copper avers
The re-inforcing laminate may be made from a variety of new
cycled material. which can be selected to impart varying rformance aspects, eg, strength, electrical or heat insulation, oz referably in order to utilise low cost indigenous materials such as wood, plant or natura class fibre or synthetic materials-preferably fibrous wastes
recycling. in the case of fibrous materials. these wouja preferably be woven to provide ma::imum strength/weight ratio.
All products have the following common attributes
*Improved strength/aluminium or copper weight
ratio
* Good corrosion and weather resistance
* Excellent surface finish * Use largely recycled & or waste
products as a core and are themselves
partially recyclable
* Are near net shaped product with low
energy requirements for initial
production and product manufacture
Have potential for volume manufacture
using a novel combination of two
new non-ferrous metal process ing
technologies invented in the 5rr Are high performance products offering high performance/cost ratio Specific embodiments of the invention will now be described by way of examples. with reference to the accompanying drawing. in which Figure 1 shows in section, a three part, circular tube, of sandwich construction. Other structural shapes, including rectangular hollow section tubes are envisaged but not
Illustrated.
Referring to Figure 1. the composite product comprises inner 4, and outer 1, claddings of thin gauge aluminium or copper.
enclosing an inner reinforcing laminate 5. made from a variety of new or recycled waste materials (eg of thin gauge steel, or wood. plant. natural or synthetic materials. These may be incorporated in fibre. sheet. woven or solid form. Innovative extrusion and tube drawing techniques are proposed for volume manufacture and to ensure intimate contact between each laminate layer. in order to impart maximum impact resistance to the aluminium. This volume production process is to be the subject of a separate patent application.
