Methods of pre-cured (wet-out) composite lay up, are improved upon by embroidering, sewing, stitching, bundle-wrapping, tying, etc., substantially between
layers and substantially normal, or in the “Z-direction” to the lay up with a wet or pre-cured
fiber bundle or tow. The pre-cured tow is embroidered, etc. either in with a like, homogeneous wet to wet layering or a heterogeneous non-similar layering, between double or multiple
layers. Heterogeneous examples include differing material types among
layers, laying and embroidering in objects or voids, as well as wet-laminating / sewing in with an already-dry (set / cured) layer.
