Ceramic Matrix Composite Preform

I need through-thickness reinforcement or a near-net shape. Who weaves or braids preforms?

What it is

Near-net dry reinforcement built by three-dimensional weaving, braiding or stitching before resin is introduced. Puts fiber through the thickness, which is where two-dimensional laminates delaminate.

Typical dimensions
Made to the part; no standard sizes.
Also known as
3D preform, braided preform, woven preform, near-net preform

    3D woven preforming is directly applicable to ceramic matrix composites, and AEC has a stated hypersonics collaboration with Spirit. Whether they weave ceramic fiber specifically was NOT established. Verify before relying on this.

3D Weaving and Braiding 1

Building near-net dry preforms with fiber running through the thickness, by three-dimensional weaving, braiding or stitching. Addresses the delamination that limits conventional laminates.

    Silicon carbide and ceramic are named explicitly in the company's yarn list. Weaving SiC fibre is the front end of a SiC/SiC ceramic matrix composite: this step produces the dry reinforcement, and the ceramic matrix is introduced afterwards by infiltration, so a buyer needs a CVI or PIP source downstream of this. The yarn list including ceramic and silicon carbide and the 3D continuous weaving capability are stated in separate places on the site; that these particular yarns run through the 3D process is NOT stated. Held at medium for that reason -- confirm before designing to a 3D woven SiC preform.
