Disclosed herein are composite structures having improved heat aging and interlayer adhesion properties, processes for making them, and end use articles. The composite structures comprise a second component overmolded onto a first component and wherein the surface of the first and optionally of second component comprise a copper based heat stabilizer thereby providing superior bond strength between components compared to polyhydric alcohol based heat stabilizers.

Composite structures having improved heat aging and interlayer bond strength

Disclosed are composite structures having improved heat aging, processes for making them, and end use articles. The composite structures comprise a polyamide matrix resin composition comprising copper based heat stabilizer; a fibrous material and a polyamide surface resin composition comprising surface heat stabilizer; wherein the surface heat stabilizer is different than the copper based heat stabilizer.

Metal coated organic polymer compositions are useful as vehicular transmission parts. Such parts may have lighter weight, and/or superior corrosion resistance, and/or be more easily fabricated than similar conventional transmission parts.

Vehicular transmission parts

Metal plated organic polymer compositions are useful as vehicular electronic and electrical housings. Such housings may have lighter weight, better strength and/or stiffer and may be more easily made than conventional housings.

Vehicular electrical and electronic housings

The present invention relates to the field of overmolded polyamide composites structures and processes for their preparation. The disclosed overmolded composite structures comprise a first component having a surface, which surface has at least a portion made of a surface polyamide resin composition, and having a fibrous material impregnated with a matrix resin composition, and comprise a second component comprising an overmolding resin composition. The second component is adhered to the first component over at least a portion of the surface of said first component. One of the overmolding resin composition and the surface polyamide resin composition is made of a polyamide composition comprising a blend of one or more semi-aromatic polyamides (A) and one or more fully aliphatic polyamides (B) and the other of the overmolding resin composition and the surface polyamide resin composition is made of one or more polyamides.

Overmolded polyamide composite structures and processes for their preparation

Metal plated organic polymer compositions are useful as vehicular engine oil pans. Such oil pans may have lighter weight, and/or superior corrosion resistance, than conventional metal oil pans.

Vehicular oil pans

Painted composite articles having good mechanical properties and smooth surface appearance comprising a reinforced thermoplastic polymeric components, a film, and a coating.

Painted composite thermoplastic articles

Disclosed herein is a type of two-shot molded article, comprising a metallizable composition and a less-metallizable composition, that can be partially coated with metal, as well as methods of making the articles.

Plastic articles, optionally with partial metal coating

A semiaromatic polyamide composite article comprising a first component comprising a fiber-reinforced material comprising a polyamide composition and reinforcing fibers and having a tensile modulus of at least about 16 GPa as measured by ISO method 527-2:1993 at a rate of 5 mm/min on test specimens having a thickness of 4 mm, a second component comprising a polyamide composition, and an optional tie layer therebetween. The polyamide composition of first component and/or the second component is a semiaromatic polyamide compositions. The second component is prepared by injection molding and/or injection-compression molding the semiaromatic polyamide composition onto the first component.

Semiaromatic polyamide composite article and processes for its preparation

Thermoplastic polyamide compositions consisting essentially of 75-90 weight percent nylon 6, nylon 66 or nylon 66/6 blends (nylon 6.ltoreq.50%) with 10-25 weight percent ethylene ionomer containing softening comonomer are characterized by a unique combination of high stiffness and toughness, and freedom from mold deposit.
