The present invention relates to fiber composite plastic (11, 13) comprising a polymer (40, 41) and at least one textile (50), which has at least one palpably inhomogeneous surface (60, 61) with a textile structure and is entirely surrounded by polymer (40, 41), wherein the fiber composite plastic (11, 13) has at least one palpably inhomogeneous surface (60, 61), wherein inhomogeneities of this fiber composite plastic surface are caused by the textile structure, and a method for producing the fiber composite plastic (11, 13).

An object of the present invention is to obtain a fiber-reinforced composite material achieving both lightweight properties and mechanical properties at a high level. The present invention provides a fiber-reinforced composite material including a resin (A) and a reinforcing fiber (B), and having: a porous structure portion having micropores with an average pore diameter of 500 μm or less as measured by a mercury intrusion method; and a coarse cavity portion defined by the porous structure portion and having a maximum length of more than 500 μm as a cross-sectional opening portion.

A method for producing elastic laminates includes gripping first and second continuous elastic films in respective gripping zones by respective first and second stretching members, transversely stretching the first and second continuous elastic films by rotating said first and second stretching members about respective first and second axes of rotation inclined with respect to each other, and releasing the transversely stretched first and second continuous elastic films from the respective first and second stretching members in respective release zones aligned along a common transverse release line.

An elastomeric composition, including at least one skin layer and a core layer, with non-blocking properties such that the elastomeric composition can be wound is provided. The core layer includes an elastomer, and the skin layer includes an elastomer, which may be the same or different from the core layer, and a non-elastic polyolefin. Further, the skin layer can be present as a small portion of the total elastomeric composition, and may maintain the elastic efficiency of the composition.

An object of the present invention is to provide a laminate having a smaller transmission loss in a high frequency band.

A laminate having a metal layer and a resin layer in contact with at least one surface of the metal layer, in which a dielectric loss tangent of the resin layer at a temperature of 23° C. and a frequency of 28 GHz is less than 0.002, and an average length RSm at an interface between the metal layer and the resin layer in a cross-section along a thickness direction of the laminate is 1.2 μm or less.

A polymeric film, sheet, or extrusion coating is formed as a multilayered structure having at least one A layer and at least one B layer. The polymeric film, sheet, or extrusion coating is able to include at least 30% recycled content resin while also exhibiting improved stiffness and strength relative to films with purely virgin polymers. One embodiment of the present invention further presents improved oxygen barrier properties relative to existing films, sheets, or extrusion coatings. Due to the strong structural properties, the polymeric film, sheet, or extrusion coating allows for the inclusion of recycled content into applications where recycled content has previously not been able to be included, such as flexible food, pharmaceutical, or cosmetics packaging.

A blow-molded bottle for a carbonated beverage includes a threaded mouth, a cylindrical side wall, a bottom, and a standard fill capacity of 37.5 mL to 105 mL. The bottle is blow-molded from a laminated preform including an outer layer formed from polyethylene terephthalate, an intermediate gas barrier layer formed from a polyamide comprising a dicarboxylic acid component and a diamine component comprising m-xylylenediamine, and an inner layer comprising polyethylene terephthalate. The laminated preform may weigh from about 4 to 16 grams. The polyamide layer provides the bottle with excellent resistance to carbon dioxide, hydrogen, and nitrogen transmission and prevents the degradation of nutrients and flavors.

A staple cartridge assembly for use with a surgical stapling instrument includes a staple cartridge including a plurality of staples and a cartridge deck. The staple cartridge assembly also includes a compressible adjunct positionable against the cartridge deck, wherein the staples are deployable into tissue captured against the compressible adjunct, and wherein the compressible adjunct comprises a first biocompatible layer comprising a first portion, a second biocompatible layer comprising a second portion, and crossed spacer fibers extending between the first portion and the second portion.
