Abstract
In panels for use particularly in the aeronautics industry comprising a metal support foil to which is adhered a fiber-reinforced metal matrix layer, the fibers being of high mechanical strength and modulus, the invention provides the improvement of interposing a thin layer of a bonding metal or alloy between the support foil and the fiber-reinforced metal matrix layer. The bonding metal layer serves to improve the adhesion of the metal matrix to the support foil and enables the metal matrix layer to be produced under less severe conditions.
Claims12
A process for the production of a panel, which comprises the steps of:
- (i) depositing a thin layer of a bonding metal or alloy on a metal support sheet, the thickness of the bonding layer being between 0.05 and 10 microns,
- (ii) positioning a layer of spaced apart reinforcing fibres on the bonding metal or alloy layer, and
- (iii) spraying a metal by means of an arc plasma torch on to and through the reinforcing fibres to form a metal matrix reinforced with the fibres, and to melt the bonding metal, thereby bonding the reinforced metal matrix to the support sheet.
