Description

1 IMPROVEMENTS IN OR RELATING TO WOUND COMPOSITE STRUCTURES This invention
relates to composite structures which are achieved by winding a metal strand material iround or with a ceramic filament.
In our co-pending patent application 8823023.0 which is incorporated herein by virtue of this reference, there is described a method of forming lightweight structures comprising ceramic filaments which have Titanium wires twisted around them. Those structures are then wound about each other in the manner of a multi strand rope and thereafter hot formed.
The advantage gained by the structure disclosed in application no 8823023. 0, is that the ceramic filaments are separated from each other, which is a critical requirement where the wound structures are to be further formed. by hot pressing or the like, into finished shapes.
The present invention seeks to provide a further improvement in the manufacture of such lightweight structures.
According to the present invention, in the method of manufacturing a lightweight article which includes the steps of winding lightweight metal wire and ceramic filamentsj, then winding the resulting structure into a preform, the additional step of filling the interstices in the preform with a metal so as to provide a dense structure in final form.
The invention will now be described, by way of example and with reference to the accompanying drawing which is an end view of a ropelike structure of ceramic filaments and lightweight wires, which incorporate an embodiment of the present invention.
Referring to the drawing. Ceramic filaments 10 have in the present example, Titanium wires, some of which are indicated by the numeral 12, wound about them. The wire wound structures are then wound about each other to make, at least in the present example, a three strand ropelike li 2 1 structure 14. The arrangement is more fully disclosed in Fig 5 and related description in co-pending application
8823023.0. 1 What is not disclosed in co-pending application 8823023.0 is a matrix material of metal 16 which is infiltrated into the interstices of the structure after it has been shaped into a pre-form e.g. a ring (not shown).
The inf iltrated metal must be of a kind which has a lower melting point than the Titanium wires and, by way of example can be magnesium, aluminium, an appropriate aluminium alloy or nickel.
Infiltration by the metal can be achieved by the application thereof in liquid form or in vapour form. This implies the need for the application of heat and that method of application should be chosen, which will achieve the minimum time during which the structure will be exposed to the heat, so as to reduce the likelihood of undesirable reaction between the ceramic filaments and the liquid metal and/or g4s.
on completion of the infiltration process, a dense assembly is achieved which is the final desired form, thus obviating the need for compression of the preform.
However metal wires and ceramic filaments are wound into a common preform structure, interstices will be generated. The present invention is thus applicable to all wound preforms.
