Such methods can produce lightweight, impact resistant, FRP components that may be used in various structural applications, including in automobiles.

METHOD FOR PRODUCING AN ELASTOMERIC SKIN HAVING A GRAINED SURFACE
20170239851 · 2017-08-24 ·

The present invention relates to a method for producing an elastomeric grained skin which comprises at least an elastomeric skin layer and a coating layer overlying the skin layer. The skin has at least a portion which hasa grained surface, which comprises at least one elastomeric skin layer and which has at least one coating layer overlying the skin layer. To produce the skin a coating composition is applied onto at least a portion of a mould surface, which portion is grained, to produce said coating layer; and the elastomeric skin layer is moulded at least against a back side of said coating layer to produce said portion of the elastomeric skin. In order to accent the grain texture so that it stands out more clearly and so that the visibility thereof is less dependent on the direction of the incident light and the position of the viewer use is made of a coating composition which comprises effect pigment particles contained in a transparent or translucent medium.

20220305745 · 2022-09-29 ·

Embodiments of the present disclosure provide systems and methods for producing a moulded component, for example a component for an automobile, having at least two unidirectional fibre portions. The unidirectional fibre portions are joined together at nodal points in a first step to produce a network of unidirectional fibres with over-moulded nodal points. The network of unidirectional fibres with over-moulded nodal points is then placed in a large mould tool along with a second moulding material. The large mould tool is then closed to produce a part that comprises the network of unidirectional fibres embedded within the second moulding material.

20220032510 · 2022-02-03 ·

A method for producing an elastomeric skin having visually spotted appearance may include providing a liquid skin forming composition having solid spot forming particles having a longest dimension that is at least 40 μm and spraying the liquid skin forming composition in the form of a spray of droplets onto a mold surface. The provision of solid spot forming particles that are comparable in size to the droplet size may aid in projecting the solid spot forming particles forward upon impact on the mold surface such that a percentage thereof appear visible on the front face of the elastomeric skin after demolding thereby resulting in a front face with a spotted appearance without having to use multiple liquid skin forming compositions.

PLASTIC COMPOSITE PANEL AND ASSOCIATED PRODUCTION METHOD

A method for producing a plastic composite panel which is provided as a layer structure. The method includes providing a film layer structure comprising an adhesive layer which is arranged between two transparent plastic films. The film layer structure is pre-molded to assume an approximately final shape and is arranged in a molding tool so that a first main surface of the film layer structure is towards the molding surface of the molding tool and so that a cavity is formed between the second main surface of the film layer structure and a surface of the molding tool. The film layer structure is then back-molded in a thermal molding method step while introducing a thermoplastic material into the cavity to provide the layer structure. A pre-molding and back-molding step, a rigidification of the thermoplastic layer, and a demolding of the layer structure is further performed.
