My project is about Synthesis of PVA fibre reinforced Aluminium oxide composite for Ballistic application.
Hi
Alumina composites for ballistics citations. The first might be the most relevant to the question you pose but all three share similarity to your topic of interest. The last one I included as it is not Al2O3 by concrete. So that gives you fiber reinforcement from a different approach. Sometimes worth looking from a different approach. Hope these help you out. Good luck.
This may help with the processing concerns:

PVA reinforced concrete, maybe similar to what you want:

Good work and best regards, Pierluigi Traverso.
Your project seems quite complex. Sintering temperature of alumina is for above the degradation temperature of all polymers. You could use preceramic polymers make in situ alumina but, even preceramics need high temperature for crystallization (> 500 °C). Another idea is to infiltrate your prefrom by molten aluminium in oxidizing atmosphere, but the temeprature is still to high for your fibers.
