Aluminium (titanium) based composite material reinforced with continuous boron (SiC, steel) fibres.
The technology of preparation of metal matrix composite materials reinforced with continuous fibres is based on the production of monolayers of fibres wound and fixed onto aluminium or titanium foil by pressing or plasma spraying. Monolayers are then stacked according to required fibre orientation respecting the strength characteristics of final product, and vacuum pressed at elevated temperatures. Sheets, panels and tubes can be produced.
The main advantage of these composite materials is the high strength (more than 1500 MPa) and modulus of elasticity (cca 250 GPa) at low density of components (the density is close to the density of Al or Ti, respectively).
The composite material can be used for very stiff rods, frames, holders of optical systems, robot arms, turbine blades and everywhere where low mass, high stiffness and dimension stability of components are required.
The technology has been developed and tested. Properties of composite material particularly of the Al-B system have been determined and investigated into details. This composite material is due to its high costs produced only on demand for precisely defined applications. Well known application is the framework of the American „Space shuttle“. The technology is not further developed, it is ready for introduction into practice.
