A NEW APPROACH TO HIGH PERFORMANCE REINFORCED ALUMINIUM COMPONENTS USING CONTINUOUS FIBRES WITH PREDETERMINED ORIENTATION

Objetivo

The aim of this project is to develop techniques for the manufacture of aluminium MMC's with orientated continuous ceramic fibres.

The potential of aluminium MMC is currently hindered by the technical limitations of short/medium fibres and the high cost of long fibre reinforcement. This project seeks to overcome these technical and cost limitations.
The know-how for producing short ceramic oxide fibres preforms, including the related deshotting techniques and for manufacturing short fibre reinforced squeeze cast MMCs has been assessed. The pilot production of continuous ceramic oxide fibres in multifilament yarn, suitable for undergoing processing into textile products, has been established.

A specially designed loom for weaving 3D oriented preforms, initially tested on commercially available long alumina fibres, has been demonstrated suitable for producing ceramic preforms for composites within a significant range of shapes (in terms of cross sections). Non destructive preform testing procedures have been identified in fine focus X-ray technique and nuclear magnetic resonance.

Mathematical modelling of infiltration by both direct and indirect squeeze casting has been developed and implemented on simulation software, then experimentally validated and applied to optimisation of components and processes configurations.

The composite testpieces obtained by direct and indirect squeeze casting have been evaluated considering the needs of industrial end users.

The complete pre-commercial process routes for the new kinds of composite have been established and some of the properties exhibited by the test pieces are attractive for applications.
A continuous ceramic fibre will be developed together with novel preform manufacturing techniques and testing procedures.

Preforms will be infiltrated using both direct and indirect squeeze casting, optimization of process parameters will be achieved by experimentation with integrated computer simulations. The acquired data will be applied to the manufacture of a complex shape similar to a commercially available high performance component.

The economics of the process route will be analyzed. This project will give a better fundamental understanding of continuous ceramic fibre manufacture and preform processing for squeeze cast infiltration. The merits of direct and indirect squeeze casting in this context will be evaluated.
