According to one embodiment, a system for manufacturing a fully impregnated thermoplastic prepreg includes a mechanism for moving a fabric or mat and a drying mechanism that removes residual moisture from at least one surface of the fabric or mat. The system also includes a resin application mechanism that applies a reactive resin to the fabric or mat and a press mechanism that presses the coated fabric or mat to ensure that the resin fully saturates the fabric or mat. The system further includes a curing oven through which the coated fabric or mat is moved to polymerize the resin and thereby form a thermoplastic polymer so that upon exiting the oven, the fabric or mat is fully impregnated with the thermoplastic polymer. During at least a portion of the process, humidity in the vicinity of the coated fabric or mat is maintained at substantially zero.

A method and apparatus for applying a faux wood grain finish to plastic architectural plastic boards. The method employs a climate-controlled area for denibbing of boards to prepare a surface and a sprayer to achieve a desired depth of color. A wiper spreads the sprayed on material to form a faux grain finish which may include faux wood knots. The boards are directed through a combination infrared and convection oven having independent curing zones providing specific drying profiles. Once cured, the boards are cooled with forced air cool down fans and transferred into a climate-controlled area for applying a topcoat. The topcoat board is passed through an oven set to a defined temperature for curing and cooled down with forced air cool down fans before packaging and shipping.

A method for arranging nanotube elements within nanotube fabric layers and films is disclosed. A directional force is applied over a nanotube fabric layer to render the fabric layer into an ordered network of nanotube elements. That is, a network of nanotube elements drawn together along their sidewalls and substantially oriented in a uniform direction. In some embodiments this directional force is applied by rolling a cylindrical element over the fabric layer. In other embodiments this directional force is applied by passing a rubbing material over the surface of a nanotube fabric layer. In other embodiments this directional force is applied by running a polishing material over the nanotube fabric layer for a predetermined time. Exemplary rolling, rubbing, and polishing apparatuses are also disclosed.

Methods of making fiber-containing prepregs are described. The methods may include the steps of providing a plurality of fibers, and applying a reactive resin composition to the plurality of fibers to make a mixture of the plurality of fibers and the resin composition. The reactive resin composition may include at least one of monomers and oligomers capable of polymerizing into a polymerized resin matrix. The mixture may be heated to a polymerization temperature where the monomers, oligomers, or both polymerize to form a fiber-resin amalgam that includes the polymerized resin matrix. The fiber-resin amalgam may be formed into the fiber-containing prepreg. Also described are methods of forming a fiber-reinforced composite that includes the prepreg.

Embodiments relate generally to marine geophysical surveying. More particularly, embodiments relate to a wax application system for application of a wax coating to a surface of a streamer. An embodiment may comprise a marine geophysical survey system. The marine geophysical survey system may comprise a streamer and a wax application system operable to receive the streamer on deployment and apply a wax coating to the streamer as the streamer is being deployed from a survey vessel into a body of water.
