    摘要: To provide a method that is capable of dividing a composite material in which a brittle material layer and a resin layer are laminated, without generating a crack in an end face of the brittle material layer.
    This invention is a method for dividing a composite material 10 in which a brittle material layer 1 and a resin layer 2 are laminated, including: a resin removing step of irradiating the resin layer with a laser beam L1 oscillated from a CO 2 laser source 20 along scheduled dividing lines DL of the composite material to form a processing groove 25 along the scheduled dividing lines; and after the resin removing step, a brittle material removing step of irradiating the brittle material layer with a laser beam L2 oscillated from an ultrashort pulsed laser source 30 along the scheduled dividing lines to form a processing mark 11 along the scheduled dividing lines. In the resin removing step, in a region IS where the scheduled dividing lines intersect, the laser beam oscillated from the CO 2 laser source is not irradiated multiple times, or an irradiation amount of the laser beam is decreased relative to an irradiation amount in a region other than a region where the scheduled dividing lines intersect.

    摘要: Provided is a glass film-resin composite, which prevents the breakage of a glass film and enables the production of an elongated glass film. The glass film-resin composite of the present invention includes: an elongated glass film; and a resin tape arranged on at least one surface of the elongated glass film, wherein the resin tape is linearly arranged at least near each of both ends in a widthwise direction of the elongated glass film in one surface of the elongated glass film, and wherein the resin tape includes an adhesive layer, and the adhesive layer is directly arranged on the elongated glass film.

    摘要: There is provided a method and the like capable of dividing a composite material without making cracks appear on end faces of its brittle material layer subjected to the division and without making end faces of its resin layer subjected to the division suffer serious thermal degradation and capable of providing the composite material subjected to the division with a sufficient bending strength. The present invention provides a method for dividing a composite material 10 including a brittle material layer 1 and a resin layer 2 that are laminated together, the method includes: a resin removing step of applying laser light L1 oscillated from a CO 2 laser light source 20 to the resin layer along a planned division line DL of the composite material, so that a processed groove 24 is formed along the planned division line; and a brittle material removing step of applying, after the resin removing step, laser light L2 oscillated from an ultrashort pulsed laser light source 30 to the brittle material layer along the planned division line, so that processed marks 11 are formed along the planned division line. The processed marks formed in the brittle material removing step open on the resin layer side and do not penetrate through the brittle material layer.

    摘要: Provided is a glass film-resin composite which makes it possible to obtain a long-length (e.g., 500 m or more-long) glass roll. The glass film-resin composite comprises a glass film, and a resin tape laminated to at least one surface of the glass film through an adhesive, wherein the width 1 (mm) of the resin tape satisfies the following formula (1). l ≡ a E g t g E p t p (where: a represents a reinforcement coefficient (mm ∗ (µm) 1/2 ) which is 1.10 or more; Eg represents the Young's modulus (GPa) of the glass film; Ep represents the Young's modulus (GPa) of the resin tape; tg represents the thickness (µm) of the glass film; and tp represents the thickness (µm) of the resin tape.)
