L'invention concerne un procédé pour la réalisation d'une pièce (100) composite à renfort fibreux continu à partir d'une préforme sèche, lequel procédé comprend : a. une opération de drapage à plat d'une première stratification (311, 312) de plis secs déformables; b. le positionnement sur ladite première stratification d'un noyau (200) thermoformable s'étendant sur une partie de la surface de la première stratification; c. une opération de drapage d'une deuxième stratification (321, 322) de plis secs déformables, s'étendant au dessus du noyau et jusqu'à la première stratification; d. une opération de couture (410, 420, 430) suivant un contour défini, ladite couture liant et s'étendant entre la deuxième et la première stratification; e. placer la préforme obtenue à l'issue de l'étape d) dans l'empreinte tridimensionnelle d'un moule (600); f. imprégner la préforme sèche d'un polymère; comprenant ente l'étape d) et l'étape g) une étape consistant à : j. thermoformer la préforme comprenant le noyau (200) à la forme de la pièce.
摘要:
The present invention relates to a display film and, more particularly, to a display film comprising a substrate layer and a coating layer formed on one surface of the substrate layer, wherein a first critical radius of curvature measured in a direction in which the side surface of the coating layer becomes concave is at most about 10 mm, and a second critical radius of curvature measured in a direction in which the side surface of the substrate layer becomes concave is at most about 5 mm. The display film according to the present invention has a high surface hardness while exhibiting superior flexibility in both directions vertical to the plane direction of the film and thus is suitable for application as an outer window film for a display and particularly has the property of being applicable to a flexible display.

Disclosed herein is a transparent protective covering to protect a windshield from bugs encountered during travel on highways or freeways. In a preferred embodiment, the invention aims to provide a transparent structure used for the protection of a windshield. The structure according to the invention is comprised of a plurality of transparent films that are coupled together, wherein the transparent film has a first side, a second side, and at least one film removing means at one of the edges of the transparent film. The removing means is provided using a thin string attached to each of the transparent films, which tears the film.

A multilayer produce packaging film includes a first layer and a chlorine dioxide-producing layer. The chlorine dioxide-producing layer includes a polymer composition and a plurality of chlorite ions. The chlorine dioxide-producing layer is substantially free of an energy-activated catalyst and is substantially free of an acid-releasing compound. However, the film is capable of generating chlorine dioxide when exposed to UV light and moisture.
摘要:
A composite thermal barrier and methods of applying the composite thermal barrier to a metallic surface within a combustion chamber of an engine. The composite thermal barrier includes at least one metallic support structure, a metallic skin, and an insulation material. The metallic support structure is connected to a metallic surface within the combustion chamber of the engine. The metallic skin is disposed adjacent to the metallic support structure to define a void space between the metallic skin and the metallic surface. The insulation material is contained within the volume to form the composite thermal barrier.
