Single-Crystal Mullite for Fibre-Reinforcement of CMCs and MMCs | Research Capability & Technology Portfolio

Single-crystal mullite is considered a prime candidate for reinforcement in ceramic matrix composites (CCMs) and metal matrix composites (MMCs) suitable for military armour. Processes suitable for world-first industrial-scale production of single-crystal mullite fibres

Competitive advantage

Although mullite is recognised as the foremost reinforcement candidate for CMCs and MMCs, it is not currently available commercially.
Through the University’s globally-patented technology, and in partnership with an Australian company that holds a mining lease covering the world’s largest resource of the raw material, this resource can uniquely be used to fabricate ultra-high-purity mullite fibres.

Impact

Stronger, lighter military armour

Successful applications

Commercialisation of the technology in collaboration with Vecor Australia Pty Limited and TopTung Limited
Single-crystal mullite fibre-reinforced aluminosilicates for mechanical, thermal, and chemical applications
Separable single-crystal mullite fibres for ceramic matrix composites (CMCs) and metal matrix composites (MMCs)

Capabilities and facilities

Ceramic processing (aligned and separable fibre production)
Materials characterisation and analysis
Mechanical testing at both room temperature and high temperatures
