Abstract
The present invention relates to a multilayer composition comprising a surface layer comprising a thermoplastic polymer A and a substrate layer comprising a polymeric composite material based thermoplastic (meth)acrylic matrix and a fibrous material as reinforcement. The multilayer composition is suitable for mechanical or structured parts or articles with a decorative surface aspect. The present invention concerns also a manufacturing process for multilayer mechanical or structured parts or articles and three-dimensional mechanical or structured parts.
Claims15
A multilayer mechanical or structural wind turbine part comprising
- a) a layer comprising a polymer A, and
- b) a layer B comprising a polymeric composite material wherein the layers a) and b) are adhered together, and wherein said polymeric composite material comprises a polymeric thermoplastic (meth)acrylic matrix and a fibrous material as reinforcement wherein the fibrous material comprises either a fiber with an aspect ratio of the fiber of at least 1000 or the fibrous material has a two dimensional macroscopic structure.
A method for forming a multilayer mechanical or structural wind turbine part comprising,
- a) stacking at least one first thermoplastic composite layer A, at least one middle thermoplastic layer B, and at least one second thermoplastic composite layer C, wherein at least one of said first or second thermoplastic composite layer comprises a polymeric thermoplastic (meth)acrylic matrix and a fibrous material as reinforcement wherein the fibrous material comprises either a fiber with an aspect ratio of the fiber of at least 1000 or the fibrous material has a two dimensional macroscopic structure,
- b) laminating said stack of at least three layers, using heat and pressure,
- to form a multilayer mechanical or structural wind turbine part.
