Comparison Study of the Processing Methods and Properties for Zirconium Silicate Fibrous Monoliths

Abstract

ZrSiO4/ZrSiO4 fibrous monoliths (FMs) have been fabricated using both ram and screw extrusion processing methods to form unidirectional [0⁰] architectures. Ram extrusion has been the traditional process for fabricating FMs, in which a controlled-geometry feedrod containing the cell and cell-boundary phases as ceramic/polymer blends is forced through a die. Conventional screw extrusion has also been used more recently to fabricate FM filaments. Both techniques resulted in FMs that exhibit graceful failure in flexure. Peak strengths are in the range of 90-100 MPa with load retention after fracture occurs.
