An object of the present invention is to provide a pressure vessel that is light in weight and has a sufficient internal capacity as well as excellent durability. The present invention provides a pressure vessel (1) including: a cylindrical straight body section (10) and dome sections (11) provided at both ends of the body section (10), wherein: the body section (10) and the dome sections (11) are composed of a resin main body (2), and an outer shell (3) made of a fiber reinforced resin material, the outer shell (3) being provided on the outside of the main body (2); each of dome sections (2b) of the main body (2) has pinch-off regions (12) extending from a tip of the dome section (2b) toward the body section (2a); and when a distance from the tip of each of the dome sections (2b) to a boundary between the body section (2a) of the main body (2) and each of the dome sections (2b) in an axial direction of the body section (2a) is 1, an end (12a) of each of the pinch-off regions (12) opposite to the tip of the dome section (2b) is located in a region where an distance from the tip of the dome section (2b) in the axial direction of the body section (2a) is less than 1.

The present disclosure provides a method for producing electrically conductive 3D structures by immersing a substrate having a build surface into a vat containing a liquid photopolymer resin which includes a conjugated polymer, controlling a thickness of a layer of the liquid photopolymer resin on the build surface so that when the liquid photopolymer resin is photopolymerized a base layer of preselected thickness of resin is produced, followed by projecting a beam of radiation having a preselected pattern down onto a top surface of the first layer of the liquid photopolymer resin for long enough to effect photopolymerization of the layer of liquid photopolymer resin; and repeating step a), b) and c) a plurality of times on top of the base layer such each layer of the 3D object is selectively photopolymerized on top of the previously photopolymerized layer to produce the 3D structure. The presence of the conjugated polymer results in the final 3D structure exhibiting electrical conductivity.

A brake pad, a mixture of materials for forming a brake pad, and a method for forming a brake pad.

A flame retardant article has excellent flame retardancy. The flame retardant article contains a cured resin member that is obtained by curing a thermosetting resin composition containing a thermosetting resin. The cured resin member forms an oxygen insulating carbonized layer when being burned. The cured resin member is present in at least a part of a surface of the expanded member obtained by expanding a thermoplastic resin composition containing a thermoplastic resin. The thermoplastic resin generates a residue when heated to 600 C. at a temperature increase rate of 10 C./minute under a nitrogen atmosphere.

Aspects of the present disclosure generally describe polyarylether ketones and methods of use. In some aspects, a composition includes one or more polymers of formulae (I), (II), or (III): ##STR00001## ##STR00002##

A method for molding a polymer composition comprises the steps of (a) providing an apparatus comprising a die and a mold cavity, (b) providing a polymer composition, (c) heating the polymer composition to a temperature sufficient to melt the polymer composition, (d) extruding the molten polymer composition through the die to form a parison, (e) capturing the parison in the mold cavity, (f) blowing a pressurized fluid into the parison, (g) allowing the molded article to cool, and (h) removing the molded article from the mold cavity.

The present invention provides a method of producing the composite comprising: a) melt blending the matrix with the fibers to produce a melted composite, b) injecting the melted composite into a mold and allowing the melted composite to solidify and, c) removing at least a portion of the outermost layer of a composite such that the fibers protrude from the surface of the composite. Also provided is composite produced by the methods of the invention comprising soft and hard fibers embedded in a soft rubber-like matrix, wherein the fibers protrude from the composite's surface. In specific embodiments, the composite comprises carbon fibers and poly(p-phenylene-2,6-benzobisoxazole) (PBO) fibers in a thermoplastic polyurethane (TPU) matrix, wherein the fibers protrude from the composite's surface. Slip-resistant product comprising the composite are also provided.

A tube-in-tube assembled parison for preparation of an elongated medical device. The parison if formed by assembling in tube-in-tube fashion a first tube of orientable polymer material and a second tube formed of orientable polymer material disposed around the first tube, with an adhesive tie layer disposed between the first and second tubes. The tubes are brought into contact to form a unitary parison. The adhesive may allow movement between the polymer layers during balloon blowing. The first tube, or the second tube, or both, may have been longitudinally pre-stretched after formation thereof but before assembly of the parison.
