Axiom Materials CerFace AX-8810 surface film improves outer finish of CMC components

Axiom Materials Inc. (Santa Ana, Calif., U.S.), one of Kordsa’s (Istanbul, Turkey) U.S.-based subsidiaries in advanced composites materials, launches its latest oxide-oxide ceramic matrix composite (ox-ox CMC) surfacing films product line, CerFace. The main focus in this product line, however, is CerFace AX-8810, which is designed to co-cure with Axiom’s ox-ox prepregs to reduce surface porosity and improve outer surface finish in high-temperature CMC components for industrial and aerospace markets.

Non-toxic and environmentally benign, CerFace AX-8810 oxide matrix is applied to an oxide carrier using advanced solution coating techniques, protecting exposed fibers and minimizing surface roughness of CMC components for operating temperatures of up to 1,093ºC. Application of the film is a single-step process, eliminating the need for traditional coatings and secondary processes.

CerFace AX- 8810 is currently being offered in rolls of 61-centimeter widths, and 23-meter lengths. Wider widths will be available in the future.

Typical industrial applications may include combustors; shrouds; gas filters for power generation; and furnace hardware. Typical aerospace applications may include lightweight aero-engine components such as the mixer, center body and cone sections; hot sections of the aircraft structures near the engine; and radomes.

Application of CerFace also enhances the precision of machining and drilling of the CMC component. Axiom plans to introduce additional CerFace films for modifying the surface properties of ox-ox CMC components in the future.
