To provide a release film not to contaminate a mold or a molded article. The present invention provides a release film comprising, an oligomer bleeding prevention layer formed of an acrylic resin or a siloxane resin and laminated on a first face of a base layer that is formed of a polyethylene terephthalate resin; a surface layer formed of a fluororesin and laminated on the oligomer bleeding prevention layer; and a surface layer formed of a fluororesin and laminated on a second face of the base layer, or an oligomer bleeding prevention layer formed of an acrylic resin or a siloxane resin and laminated on a second face of the base layer, and a surface layer formed of a fluororesin and laminated on the oligomer bleeding prevention layer that is laminated on the second face.

To provide a vehicle-interior-component manufacturing method that can suppress damage to a designed surface of a skin and can manufacture a vehicle interior component superior in appearance quality. The method includes a first step and a second step. At the first step, a layered body is sandwiched by the forming dies so as to be subjected to hot-press forming, with the layered body including a base member, a skin, and a protection sheet that are layered over each other, the base member being made of a thermosetting resin, the skin being positioned on a side of a base member surface, and the protection sheet being positioned on a side of a skin surface. At the second step, the layered body is removed from the forming die, and then, the protection sheet is peeled.

A system for forming a composite component includes a close mold tool defining a cavity that corresponds to a shape of the composite component and configured to receive a composite material. The system further includes a perforated release film defining a plurality of openings and configured to be positioned on a surface of the composite material within the cavity. The system further includes a breather configured to be positioned on the perforated release film, to allow a vacuum to be applied to the composite material through the breather and the plurality of openings, and to allow pressurized fluid to be applied to the perforated release film through the breather.

A textured release sheet includes a substrate, which has been electron beam treated, including a top side and a bottom side. A matte surface is formed on the bottom side thereof, wherein the matte surface of the surfacing material is a coating of an radiation curable material applied to the bottom side of the substrate. The coating is an UV curable acrylate mixture applied to the substrate, wherein the UV curable acrylate mixture is irradiated with UV-radiation via an excimer laser emitter to produce a UV-irradiated layer wherein the UV curable acrylate mixture is only crosslinked on the surface thereof, which produces a matting surface through the effects of a micro-convolution.

A laser-debondable composition includes an acrylic resin, a light-shielding material, an additive, and a solvent. Wherein, the acrylic resin includes at least one nitrogen-containing organic group selected from a group consisting of tertiary amino groups and secondary amino groups, an organic group having a cyclic ether group, and an organic group having a hydroxyl group, and the additive includes at least one adhesion promoter. The laser-debondable composition has excellent adhesion ability to a substrate, attachability, and solvent resistance.

A system and method for fusing at least two thermoplastic composite components together may include placing faying surfaces of the thermoplastic composite components in contact with each other, placing a separation layer over and against one of the thermoplastic composite components, and placing a multi-layer composite pressure pad over and in contact with the separation layer. The method may also include placing an activated inductor against the multi-layer composite pressure pad for induction welding the two thermoplastic composite components to each other. The thermoplastic composite components may comprise conductive fibers while the multi-layer composite pressure pad may comprise a first layer and a second layer with non-conductive fibers. The first layer may at least partially melt during induction welding of the two thermoplastic composite components while the second layer may remain rigid throughout this welding.
