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.

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.

The imprint apparatus of the present invention includes a holding unit configured to hold a mold; a particle inspection unit configured to inspect whether or not particle is present on an imprint area, in which the resin pattern is formed, of the substrate; a dispenser configured to apply an uncured resin to the imprint area; a movable unit configured to move the imprint area with respect to the holding unit; and a controller. The movable unit is capable of moving the imprint area to each of an inspection position by means of the inspection unit, an application position by means of the dispenser, and a contacting position by means of the holding unit. Also, the controller causes the inspection unit to perform inspection of the imprint area in association with the movement of the imprint area by means of the movable unit.

In some examples, an apparatus to apply a coating to a media includes a first roller to receive a continuous belt that is to receive a coating from a second roller and to transfer the coating to the media, the first roller having a variable dimension to provide an adjustable width of the continuous belt to the second roller.
摘要:
A cleaning device (10) for a linear coating machine table comprising a vacuum suction device (1) having a plurality of first suction ports (11) facing a surface of an object to be cleaned; and at least one sticky roller (12) pivoted to the vacuum suction device (1) and being rotatable, the sticky roller (12) configured to adhere impurities on the surface of the object to be cleaned is provided. By sucking small particles on the linear coating machine table by the vacuum suction device (11) and by adhering relative large particles by the sticky roller (12), the cleanness of the linear coating machine table is improved, and hence the coating effect of a substrate is improved. A linear coating machine is also provided.

A system and a method for pretreating an aluminum assembly includes selecting a blank having a thin film pretreatment layer and a lubricant coating applied to a surface. The blank is formed to a desired shape and an adhesive is applied to a selected portion of the surface. A cleaner is applied to the assembly to remove the thin film pretreatment layer and the lubricant coating from the surface except at the selected portion and a zirconium oxide conversion coating is applied to the assembly before painting.
摘要:
[PROBLEM TO BE SOLVED] To provide a method and apparatus for applying a coating material that reacts at ordinary temperatures and increases in viscosity with lapse of time or a coating material that is difficult to handle, such as an unstable slurry in which sedimentation occurs at high rate, to a high-value-added object to be coated.[SOLUTION] Before at least applying coating material to an object to be coated, the coating amount is automatically measured using a highly-accurate measuring device set in an atmosphere that does not substantially affect the measurement to control the coating amount during production. Therefore, high-quality products can be mass-produced with a low production cost.

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.
