Abstract

For the continuous development of ultra high temperature ceramic matrix
composites manufactured using reactive melt infiltration (RMI), the
influence of three different melt alloys and two preform routes on
mechanical behaviour and melt infiltration is investigated. Contact
angle and viscosity measurement are performed to describe the melt
infiltration process. The purpose of these experiments is to further
understand the RMI process and increase the mechanical performance of
the material. The infiltration height of molten metals within capillary
systems depends on the measured contact angles and viscosity as well as
the different phases present in the preform, matrix and fibre coating.
In order to successfully maintain mechanical performance, minimal
reactivity between the melt and coating/fibres is desired. Resulting
phase formations, for each manufacturing step, are investigated and
analysed using SEM, EDX and XRD. Mechanical performance is determined
using flexural strength by three-point-bending, achieving close to 400
MPa with 0/90° fabrics.
