Embodiments of the present invention may encompass gateline paddles that include a paddle body having a composite material forming an outer surface of the paddle body. The composite material may have a first surface and a second surface opposite the first surface that define an open interior therebetween. The composite material may include a fiber-reinforced resin. The paddle body may include a cellular reinforcement member disposed within the open interior. The paddle body may include a mounting region formed along a lateral edge of the paddle body. The paddle body may include a mounting block disposed within a portion of the open interior disposed within the mounting region.

A sandwich-type, composite component having an injection molded backside protective covering including 3-D structures which provide at least one pattern at an outer surface of the component is provided. The component includes a first outer layer having an outer surface, a second outer layer and a core bonded to and positioned between the outer layers and having a plurality of cavities. The covering is integrally formed from at least one elastomeric material and includes the 3-D structures bonded to the outer surface by injection molding. The 3-D structures are sized, shaped and arranged in one or more patterns at the outer surface. The one or more patterns may form a textured surface finish, a logo or indicia such as instructions at the outer surface. The component may be a vehicle interior component such as a vehicle load floor component.

A marine deck member with enhanced surface traction and the process for forming the same. The marine deck member comprises a sandwich-type composite panel made by a compression molding process. In such a process, the panel is made by subjecting a heated stack of layers of material to cold-pressing in a mold. The cellular core has a 2-D array of cells, each of the cells having an axis substantially perpendicular to the outer surfaces, and extending in the space between the layers or skins, with end faces open to the respective layers or skins. The surface traction of this type of composite panel can be enhanced for marine deck applications by controlled debossing, or embossing, of the first skin while it cools in the compression mold. The debossing effect can be effected by applying pressurized gas, e.g., pressurized air, onto the outer surface of the first skin while in the compression mold. The embossing can be effected by applying vacuum pressure on the outer surface of the first skin while in the compression mold.

In an example, a method for accelerated conditioning of a composite core sandwich coupon is described. The method includes setting a first temperature and a first relative humidity level of the conditioning apparatus, wherein a combination of the first temperature and the first relative humidity level correspond to a desired relative humidity level of the plurality of cells of the core layer at room temperature. The method includes maintaining the first temperature and the first relative humidity for a first period, wherein during the first period a core humidity of the plurality of cells in the core layer approaches the first relative humidity level. The method includes determining that the core humidity has reached the first relative humidity level. The method includes, based on determining that the core humidity has reached the first relative humidity level, adjusting the first temperature to a second temperature.
