The research demonstrated AFP of oxide-based ceramic matrix composites (CMCs), utilising a new aluminium oxide fibre/aluminium oxide matrix slit-tape material format supplied by Axiom Materials containing Nextel 610 fibres within a proprietary aluminium oxide-based matrix. This work produced a cone shaped demonstrator from the materials using AFP, whilst showing a significant reduction in material waste.

ABSTRACT
Automated fibre placement of oxide-based ceramic matrix composites was demonstrated. Tfhis was possible due to the emergence of an aluminium oxide/aluminium oxide tape material format. The material consists of Nextel 610 alumina oxide fibres with a proprietary alumina-based matrix system. Historically, aluminium oxide-based ceramic composites have been created from prepreg formats. In the current work, Automated Fibre Deposition was adapted to create oxide-based ceramic matrix composites using tape material. Key processing variables were investigated, and a cone shaped demonstrator was manufactured. The manufacturing process exhibited control over temperature, pressure and placement, whilst also reducing the material waste from 35% to less than 2%.
