Glass Fiber 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
