A braided sleeve is formed having complex geometry, including multiple geometries along the braided sleeve's longitudinal axis. In particular, along a first portion of the braided sleeve's longitudinal axis, multiple tows are intertwined with each other. Along a second portion, at least one of the tows is removed from being intertwined with the other tows and is relocated to an interior or an exterior of the braided sleeve. A third portion of the braded sleeve along the longitudinal axis includes the removed tow being intertwined with the plurality of tows again. In this manner, the braided sleeve may provide coverage of preforms with varying diameters along the longitudinal axis of the preforms.

Described herein is a sheet comprising: a multi-layer structure comprising: a plurality of layers including an uppermost layer and a lowermost layer, each of the plurality of layers having a molecular orientation that results in a stress value for each layer; wherein the stress value of at least two of the plurality of layers are non-zero and different from one another; and wherein the multi-layer structure has a net stress value that is less than the greater stress value of the plurality of layers.

A wall having a fluid impervious coating thereon and further having a monitoring arrangement which provides for monitoring the condition of the wall. The monitoring arrangement mounted on a surface of the wall

Extruded molds and methods for manufacturing composite structures using the extruded molds are disclosed. The molds may include recessed or raised longitudinal features to impart a corresponding shape to the molded composite structures. The composite structures may be panels used to construct cargo vehicles, for example.

Provided is a laminate including a base material layer, an adhesive layer having a thickness in a range of 0.1 μm to 1.0 μm, and a non-oriented sealant layer having a thickness in a range of 10 μm to 40 μm and made of a cyclic polyolefin resin, wherein one main surface of the sealant layer constitutes an outermost surface of the laminate, the other main surface of the sealant layer is bonded to the base material layer via the adhesive layer, and an adhesion strength between the base material layer and the sealant layer is 0.8 N/15 mm or more.

The invention relates to the manufacturing of porous polymer membranes by (a) providing pellets comprising a polymer matrix and particles in the ratio 90:10 to 10:90, (b) converting said pellets into a non-porous film by a solvent-free process; (c) removing said particles from said film with an aqueous composition to thereby obtain said membrane. The invention further relates to pellets useful in such manufacturing process as well as porous polymer membranes obtainable or obtained by such manufacturing process as well as textile materials and articles containing such membranes; to the use of such pellets, membranes, and articles.

A layered sheet 10 includes a substrate layer 1, and surface layers 2 and 3 configured to be layered on at least one surface of the substrate layer 1. The substrate layer 1 contains a first thermoplastic resin and inorganic fillers. The surface layers 2 and 3 contain a second thermoplastic resin and a conductive material. A content of the inorganic fillers in the substrate layer 1 is 0.3 to 28 mass % based on a total amount of the substrate layer.

A coating composition is described that can be completely biodegradable and well suited for use in laminating films to substrates. The coating composition contains a biodegradable polymer, such as a polyvinyl alcohol polymer. The coating composition can be applied to a biodegradable film and then adhered to a substrate, such as a paper substrate.

A bale wrapping system includes an emitter configured to generate electromagnetic radiation within an emitted spectrum and a wrap. The wrap includes a melt layer containing an additive absorbent to at least some electromagnetic radiation within the emitted spectrum and a solid layer substantially free of the additive.

Methods for making films including a water-soluble polymeric material and a vapor-deposited inorganic coating are disclosed. The method comprises providing a layer of water-soluble polymeric material and vapor depositing an inorganic coating to at least one surface of the layer of water-soluble polymeric material, wherein the inorganic coating comprises a metal oxide. The method further comprises forming a plurality of microfractures extending along the surface of the inorganic coating.
