Abstract:
The present invention relates to an article or layer made of a composite material comprising a plastic material reinforced with fibers, said article or layer comprising at least one segment of a predominantly two-dimensional structure with a first and a second surface and a basis thickness of the segment and at least one of the surfaces of the segment shows a surface profile with dents or knobs or dents and knobs, wherein the surface with the surface profile has a continuous basis surface, in which the dents are impressed or of which the knobs stick out, and the basis thickness of the segment is the distance between the basis surface of the surface with the surface profile and the other surface, if only one surface has a surface profile, or the basis thickness of the segment is the distance between both basis surfaces, if both surfaces have a surface profile, wherein in case of dents the distance between the surface in the area of the dent and the other surface, if only one surface has a surface profile, or the other basis surface is at least 10% less than the basis thickness and in case of knobs the distance between the surface in the area of the knob and the other surface if only one surface has a surface profile, or the other basis surface is at least 10% more and at the most 200% more than the basis thickness; and wherein at least 10% of the surface with the surface profile are knobs or dents. Furthermore, the present invention provides layered composite materials comprising such layers, methods of producing such articles or layers and the use of the articles or layered composite materials as as component or part of a component produced by or for the automotive industry or as component or part of a component of a household appliance.
Abstract:
The present disclosure refers to a polymer blend obtained by melt blending a mixture comprising: (A) 60% to 98.8% by weight of a polyolefin; (B) 0.1% to 30% by weight of at least one compatibilizer; (C) 0.05% to 20% by weight of an amino resin; and (D) 0% to 5% by weight of at least one additive, wherein the amounts of (A), (B), (C) and (D) are based on the total weight of (A)+(B)+(C)+(D), the total weight being 100%, to a film or sheet comprising the polymer blend and to the use of the film or sheet to form a bonding film for composite articles.
Abstract:
A polyolefin composition comprising: (A) from 97.0 to 45.0 wt% of a propylene-1-hexene random copolymer, (B) from 2.0 to 50.0 wt% of fibers, and (Q) from 0.3 wt% to 5.0 wt% of a compatibilizer, the sum (A) + (B) + (Q) being 100, wherein (i) the copolymer has a content of 1-hexene derived units ranging from 0.6 wt% to 3.0 wt% with respect to the copolymer, (ii) the copolymer has the melt flow rate (MFR) measured according to the method ISO 1133 (230° C, 2.16 kg) ranging from 0.2 up to 40 g/10min, (iii) the fibers are selected from the group consisting of glass fibers, carbon fibers, metal fibers, mineral fibers and ceramic fibers.
Abstract:
The present invention relates to a modular-design drum composed of a plurality of geometrically differently or equally shaped individual components, which are first fabricated as separate parts from a thermoplastic polymer and thereafter the components are assembled to the drum, wherein at least one of the components is at least partly laminated with an intermediate layer and a decorative layer, with an intermediate layer and a heat-cured outer layer or with an intermediate layer, a decorative layer and a heat-cured outer layer and to processes for the production of the modular-design drum, and to its use as inner part of tumbler dryers, washing machines, or spin-dryers.

Abstract:
The invention relates to a layered composite material containing a support made of a thermoplastic polymer, an intermediate layer which is arranged on the support and also made of a thermoplastic polymer, and a heat hardened layer which is disposed on the intermediate layer. The invention is characterised in that another resin layer (a) with a hardening degree of at least 20 % is inserted between the support and the intermediate layer and a resin layer (c) with a hardening degree of at least 60 % is inserted between the intermediate layer and the heat hardened layer.
