Abstract
Tow of substantially continuous ceramic oxide fibers having a sizing material. Tows according to the present invention are useful, for example, for making metal matrix wires.
Claims8
A tow of substantially continuous ceramic oxide fibers, wherein each ceramic oxide fiber has an outer surface, wherein at least a portion of the outer surfaces of at least some of the ceramic oxide fibers have a sizing material therein, and wherein the sizing material comprises a composition represented by the formula:
- R′O—(RO)n—H,
- wherein:
- R′ is selected from CxH2x+1, wherein x is 1-8 or —H;
- R is selected from the group consisting of —(CyH2y)—, wherein y is 1-4, and —CH2—O—(CH2)m—, wherein m=2-5;
- and
- n is chosen such that the number average molecular weight is in a range from 500 g/mole to 7,000,000 g/mole.
