Curable prepregs possessing enhanced ability for the removal of gases from within prepregs and between prepreg plies in a prepreg layup prior to and/or during consolidation and curing. Each curable prepreg is a resin-impregnated, woven fabric that has been subjected to a treatment to create an array of openings in at least one major surface. Furthermore, the location of the openings is specific to the weave pattern of the fabric.

In the preferred embodiments, the present invention provides substantially improved slit sheet cushioning products by advantageously combining novel paper properties with novel slit patterns for improved features and characteristics. In some illustrative and non-limiting example embodiments, cushioning products of the present invention can include, e.g., a novel slit sheet material in combination with extensible paper employed as, e.g., a cushioning pad or as cushioning within an envelope product, wherein the cushioning product can be substantially more resilient, but, yet, e.g., thinner for better utilization of space.

Provided is a composite (A) including a metal plate (B) and a reinforcing member (C) that is made of a resin. The metal plate (B) includes a joint portion (2) that is continuous with one end of a body portion (1), a hole that is formed through the body portion (1) in a thickness direction of the body portion (1) in the proximity of the joint portion (2), and a guide portion provided around the hole. The reinforcing member (C) continuously includes a main portion (5), a coupling portion (6) formed in the hole (3), and a locking portion (7) that is held in close contact with a surface on another side of the body portion (1). The guide portion (4) is at least one of a protruding portion provided on at least one of a rear side and a lateral side relative to the hole (3) in a direction from the body portion (1) to the joint portion (2), and a recessed portion extended from a front side relative to the hole (3) to the hole (3) in the direction from the body portion to the joint portion. In insert molding of the composite (A), a molten resin is introduced preferentially into the hole (3). With this, the joint portion (2) is formed reliably in good condition free from adhesion of the resin.

A composite panel having a plurality of carbon plies, a perforated metallic foil comprising several apertures and being directly secured to the plurality of carbon plies, and a protective layer made from resin reinforced with fibers which is secured to the metallic foil. The perforated metallic foil is embedded in the protective layer through its apertures. A free surface of the protective layer forms a top side of the composite panel. The thickness of the protective layer between the top side of the composite panel and the perforated metallic foil is at least 15 micrometers and the perforated metallic foil has a thickness of not more than 30 micrometers. The plurality of apertures in the aggregate defines an open area of not more than 40% of the surface area and a maximum distance between two opposed points in a perimeter of an aperture is equal to or less than 3 mm.

The present disclosure relates to a support substrate for a flexible display device, and a flexible display device, the support substrate comprises a bending area, a transition area, and a non-bending area, wherein the transition area is located between the bending area and the non-bending area, the bending area has a plurality of first through holes and the transition area has a plurality of second through holes, wherein an area ratio of the plurality of first through holes in the bending area is greater than an area ratio of the plurality of second through holes in the transition area.

A wear panel for mining and materials handling applications is provided. The wear panel includes a housing matrix (1) with a top surface (2), a bottom surface (3) opposite the top surface (2) and at least one cavity (4) with cavity walls (5). The cavity (4) extends through the top surface (2) and the bottom surface (3). The wear panel also includes at least one wear-resistant member (6) with a preformed shape. The at least one wear-resistant member (6) has a top surface (7) and a bottom surface (8) opposite the top surface (7). The wear-resistant members (6) are disposed in the cavity (4) and are locked into place by their preformed shape and the cavity walls (5).

Provided is a resin molded article which makes it possible to prevent breakage of a resin and collar loss at joint sections. A resin molded article (1) is formed by resin injection, and comprises a main body (2) and a joint section (3) integrally formed at an outer wall surface (4) of the main body (2) and having a cylindrical section (11) configured to insert therethrough the joint member for attaching the main body (2) to a mating member (6). The joint section (3) is formed to be asymmetric about a perpendicular plane (19) which passes through the central axis (18) of the cylindrical sections (11), and is perpendicular to the outer wall surface (4) of the main body (2).

An extensible slit sheet paper product is produced having an expandable slit pattern that forms open cells upon expansion of the paper product. The paper product is an extensible paper having an extensibility in the range from 1-9% in the machine direction and 1-5% in the cross direction. The expansion produces an array of hexagonal cells. The expanded extensible paper can be used to wrap an object for shipping by wrapping and cushioning the object in the expanded slit sheet material. The extensible, expandable slit sheet paper can be wrapped around itself to produce a void fill product.
