A thermoplastic prepreg includes a web or mesh of fibers in which the web or mesh of fibers includes chopped fibers. The thermoplastic prepreg also includes a thermoplastic material that fully impregnates the web or mesh of fibers so that the thermoplastic prepreg has a void content of less than 5%. The thermoplastic material is polymers that are formed by in-situ polymerization of monomers or oligomers in which greater than 90% of the monomers or oligomers react to form the thermoplastic material. The thermoplastic prepreg includes between 5 and 95 weight percent of the thermoplastic material and the chopped fibers that form the web or mesh of fibers are un-bonded.

A thermoplastic prepreg includes a mat, web, or fabric of fibers and hollow glass microspheres that are positioned atop the mat, web, or fabric of fibers or dispersed therein. The thermoplastic prepreg also includes a thermoplastic polymer that is fully impregnated through the mat, web, or fabric of fibers and the hollow glass microspheres so that the thermoplastic prepreg has a void content of less than 3% by volume of the thermoplastic prepreg. The thermoplastic material is polymerized monomers and oligomers in which greater than 90% by weight of the monomers or oligomers react to form the thermoplastic material.

According to one embodiment, a system for manufacturing a polymethyl methacrylate (PMMA) prepreg includes a mechanism for continuously moving a fabric or mat and a resin application component that applies a methyl methacrylate (MMA) resin to the fabric or mat. The system also includes a press mechanism that presses the fabric or mat during the continuous movement subsequent to the application of the MMA resin to ensure that the MMA resin fully saturates the fabric or mat. The system further includes a curing oven through which the fabric or mat is continuously moved. The curing oven is maintained at a temperature of between 40 C. and 100 C. to polymerize the MMA resin and thereby form PMMA so that upon exiting the curing oven, the fabric or mat is fully impregnated with PMMA.

Method for hydrophobing a cellulose substrate (1), which comprising a first side and a second side, which faces away from the first side. The method comprising the steps of drying a cellulose substrate (1) to a dry content above 80%, preferably above 85%, adding a vaporized fatty acid halide, to the first side of the cellulose substrate, and, at the same time perform vacuum sucking at the second side of the cellulose substrate, such that, the vaporized fatty acid penetrates the cellulose substrate (1) in a predetermined direction through the substrate.

Disclosed is a method for producing a polyimide laminate, the method including the steps of applying a polyimide precursor solution onto a substrate and heating the polyimide precursor solution, to thereby form a polyimide film layer on the substrate. The substrate is any plate selected from a glass plate, a metal plate, and a ceramic plate. The heating step includes irradiation with far infrared rays using an infrared heater that generates a maximum radiant energy at an infrared wavelength of 3.5 to 6 m. The highest heating temperature is preferably 350 to 550 C. The time required to increase the temperature from 180 to 280 C. during a temperature-increasing process is preferably 2 minutes or longer.

The present invention relates to coating compositions, processes for making them, and methods of application of the coating compositions. Further, the present invention relates to a process and apparatus for coating a metal substrate, for example an elongated metal tubular substrate such as a pipe. Most particularly, the coating can be used as an anti-corrosion coating on a pipe for use in oil, gas and water pipeline applications.
