Overmolded polyester composite Structure, Stability to long-term external influences, and methods of making

摘要

1. Formed over the composite structure, comprising: i) a first component having a surface wherein at least a portion of the surface is made of a resin composition for a surface and comprising a fibrous material selected from non-woven structures, textiles, fiber batts, and combinations thereof, wherein said fibrous material is impregnated with a matrix resin composition, ii) a second component comprising a resin composition for forming a top, wherein said second component is connected by adhesion to said first component of the m enshey least part of the surface of said first component and wherein the resin composition for molding over is selected from polyester compositions comprising a) one or more polyester resins, and b) from or about 0.3 to or about 3 wt.% not less three UV-stabilizers, wherein one of at least three UV stabilizers is b1), other represents b2) and another represents b3), the weight percentage is given on the basis of the total weight of the polyester kompozitsii.2. Formed on top of the composite structure of claim 1, wherein the matrix resin composition is formed from a composition comprising one or more thermoplastic polyesters, or is selected from polyester compositions comprising a) one or more polyester resins and b), or from about 0.3 to or up to about 3 wt.% of at least three UV-stabilizers, wherein one of at least three UV stabilizers is b1), other represents b2) and another represents b3), the weight percentages are based on the total weight of the polyester compositional i.3. Formed on top of the composite structure according Telegram
