Process for manufacturing a thermoplastic composite part
10773475 · 2020-09-15 · ·

This process for producing a thermoplastic composite part by laying of at least one thermoplastic composite layer on a tool includes laying on the tool a hardened first ply before the laying of the thermoplastic composite layer. The first ply is produced beforehand to the shape of the tool and includes a first material able to experience an attractive force when it is subjected to a magnetic field, and/or to an electrical potential difference, and includes a second material of a thermoplastic resin that is chemically compatible with the resin of the thermoplastic composite layer. The first ply is clamped to the tool by the effect of a magnetic field, and/or of an electrical potential difference, established at the level of the tool. In one form of implementation, the first ply is produced on a first-ply mold that is preferably of convex shape.

The method has the following steps: (a) heating the cover layers and the foam core (b) positioning the cover layers on the surfaces of the foam core, (c) positioning the foam core and the cover layers in a press or a mold which forms the completed composite part, (d) reshaping the foam core and the cover layers in the press or in the mold, wherein the cover layers can be positioned on the surfaces of the foam core, (e) cooling and bonding the cover layers and the foam core in the press or in the mold, and (f) removing the composite part from the press or from the mold.

Ultra-bright passivated aluminum nano-flake pigments

Nano-thick flakes that are either flat, and specularly-reflective in visible light or that have microroughness intentionally controlled to disperse or interfere with visible light. Coatings and inks utilizing such flakes. Method for fabrication of such flakes in partial vacuum includes the repeated multiple times deposition of a release layer over a substrate surface and a flake layer over the release layer to form a multilayer structure further reduced to individual flakes. Reactive metal is passivated inline with the deposition of the flake layer for superior corrosion resistance. Chemically-functional materials are optionally added to the release material to transfer their functionality to the surface of flake layer to create unique functional properties on a flake surface before the multilayer structure is removed from the substrate.
