Imprint method and apparatus apply an imprint material on a substrate. The imprint material includes a luminescent material that undergoes fluorescence or phosphorescence upon receiving ultraviolet light. The imprint material further includes an ultraviolet curable resin that is cured with ultraviolet light. A mold with a pattern imprints into the imprint material applied to the substrate. The imprint material applied to the substrate is cured with ultraviolet light. After releasing the mold from the substrate imprinted with the pattern, any residual resin remaining on the mold can be detected with ultraviolet light.

Embodiments of the present disclosure provide for particle-imprinted polymer films, methods of making particle-imprinted polymer films, methods for separating particles, devices or systems for separating particles, and the like.

A composite molded article in which another material is integrated on a face having grooves in a grooved resin molded article having grooves in which end parts of a fibrous inorganic filler protrude and are exposed from lateral faces of the grooves on a surface side in at least the insides of the grooves. Exposure of the end parts of the fibrous inorganic filler and formation of the grooves may be accomplished by laser irradiation, and the depth of the grooves may be at least 200 m. Another molded article comprising the other material is arranged surrounding the fibrous inorganic filler in the insides of the grooves.

A method for the hot stamping of a composite part with continuous fiber reinforcement in a thermoplastic matrix. A blank including a laminated structure of plies consisting in unidirectional tapes of fibers pre-impregnated with thermoplastic polymer is obtained. The blank is heated in the open to a temperature greater than or equal to the melting temperature of the polymer making up the matrix. The blank is then stamped.
