Processes for forming fiber reinforced composite aircraft components, i.e., aircraft components formed of a cured fiber-reinforced resin, are provided. According to specific embodiments, a finished surface of the composite aircraft component can be achieved by providing in-mold coating of the cured fiber-reinforced resin by a dried and cured film layer of a water-based primer paint material to thereby achieve a composite aircraft component having an exterior surface that does not necessarily require further finishing.

This invention relates to a wind turbine blade component, a method of manufacturing such a wind turbine blade component and a wind turbine blade comprising the wind turbine blade component. The wind turbine blade component comprising a stack of layers arranged in a first group and in a second group, wherein the layers of each group has the same width. The layers of each group is continuously offset in an edgewise direction to form a tapered edge profile. The first group of layers may be arranged relative to the second group, or in an alternating order. The layers of the first group may further have a first length which is greater than a second length of the layers of the second group.

A belt for creping a web in a papermaking process. The belt includes a surface onto which the web is transferred during the papermaking process. A plurality of openings extend through the surface, with the openings being arranged in lines that are offset from lines in the machine direction (MD) and cross-machine direction (CD) of the belt. Paper products, such as absorbent sheets, made from the belt have hollow dome regions and connecting regions between the domes, with the domes being arranged in lines that are offset from lines in the MD and CD of the paper products.

In an aspect of the invention there is provided a blast protection panel, comprising a package of fibre-reinforced resin sheets, each sheet having a dominant unidirectional fibre orientation, said package of fibre-reinforced resin sheets formed in packed stacks, each stack comprising at least four fibre-reinforced resin sheets with dominant unidirectional fibres oriented, within said each stack, alternatingly at about right angles relative to each other; and said each stack packed against adjacent stacks, said adjacent stacks comprising sheets with dominant unidirectional fibres oriented at acute angles relative said each stack thereby forming a delamination interface.

The present invention relates to fiber composite plastic (11, 13) comprising a polymer (40, 41) and at least one textile (50), which has at least one palpably inhomogeneous surface (60, 61) with a textile structure and is entirely surrounded by polymer (40, 41), wherein the fiber composite plastic (11, 13) has at least one palpably inhomogeneous surface (60, 61), wherein inhomogeneities of this fiber composite plastic surface are caused by the textile structure, and a method for producing the fiber composite plastic (11, 13).

A method and system for the characterization of equibiaxial compressive strength in 2D woven composites, such as carbon fiber reinforced laminate composites, is disclosed using induced biaxial flexure, the strain measurements from which are used to determine the equibiaxial compressive strength of the composite.
