  • Melt-spun ceramic fiber filter and method
    Patent number: 6860917
    Abstract: A method for making high temperature filter media is provided by melt-spinning a plurality of fibers of preceramic thermoplastic polymer to form a nonwoven textile web of the fibers, curing and cross-linking the thermoplastic polymer to a thermoset polymer, and thermally decomposing the thermoset polymer to ceramic. Between the melt-spinning step and the curing step, the web is formed to a filter pre-form in a green state while still pliable and malleable. The filter pre-form is cured without re-melting the thermoplastic polymer and without destroying morphology.
