The present invention relates to a painted molding article in which a paint composition is painted in a molding part formed of an injection molding thermoplastic resin composition, and the injection molding thermoplastic resin composition comprises: (a) a base resin including polyamide (a-1) and polyphenylene ether (a-2); (b) an impact modifier; and (c) a carbon fibril, wherein the polyamide (a-1) forms a matrix phase of the injection molding thermoplastic resin composition, the polyphenylene ether (a-2) and the impact modifier (b) form a domain phase of the injection molding thermoplastic resin composition, the carbon fibril (c) is dispersed on the domain phase and the matrix phase, the content of the carbon fibril (c) dispersed on the matrix phase is higher than the content of the carbon fibril (c) dispersed on the domain phase, and the ratio of weight of the carbon fibril (c) to weight of the polyamide (a-1) may be 0.006 to 0.03.

A system is described for reinforcing a thermoplastic workpiece including a subject surface and an underlying workpiece body volume. At least one substantially linear Z-pin having proximal and distal pin ends longitudinally separated by a pin body is provided. The proximal pin end is in direct contact with the subject surface. An ultrasonic energy source applies ultrasonic energy to the Z-pin to ultrasonically heat the Z-pin and thus locally melt the workpiece material of the subject surface and/or the workpiece body to create a melted workpiece material. The proximal pin end and at least a portion of the pin body of the Z-pin are penetrated into the melted workpiece material to create an inserted Z-pin length. The inserted Z-pin length is maintained in the workpiece body volume by solidified melted workpiece material around the inserted Z-pin length to reinforce the workpiece. A method of reinforcing a workpiece is also provided.

Polyparaxylylene (PPX) polymers that can be expanded into porous articles that have a node and fibril microstructure are provided. The fibrils contain PPX polymer chains oriented with the fibril axis. The PPX polymer may contain one or more comonomer. PPX polymer articles may be formed by applying PPX to a substrate by vapor deposition. The nominal thickness of the PPX polymer film is less than about 50 microns. The PPX polymer film may be removed from the substrate to form a free-standing PPX polymer film, which may then be stretched into a porous article. Alternatively, a PPX polymer article can be formed by lubricating PPX polymer powder, heating the lubricated powder, and calendering or ram extruding to produce a preform that can subsequently be stretched into a porous article. The heating and expansion temperatures are from about 80 C. to about 220 C. or from about 220 C. to about 290 C. or from about 290 C. to about 450 C.

The current disclosure is directed to an impact resistant material made from a novel melanin composite. It has been found that using these composites allows for the production of effective ballistic protection and blast containment materials.
