A cord including multifilament para-aramid yarn comprising filaments, wherein the filaments have a non-round cross section having a smaller and a larger dimension, where the cross-sectional aspect ratio between the larger and the smaller dimension is 1.5-10 and the smaller dimension of the cross section has a maximum of 50 m and wherein the para-aramid has at least 90% para bonds between the aromatic moieties. The cords have excellent fatigue properties.

The glass-fiber-yarn joined body 1 is provided with glass fiber yarns 2, 3, and a connection 5 in which a resin yarn 4 is wound around ends of both of the glass fiber yarns 2, 3, the ends being superimposed with each other. The connection 5 has a width W.sub.1 of 20 to 40 mm. When a connection diameter R as a total of diameters of the respective glass fiber yarns 2, 3 and the thickness of the resin yarn 4 wound around the connection 5 is 500 to 5000 m and a mass of each of the glass fiber yarns 2, 3 is 200 to 6000 tex, a value of a ratio of mass of each of the glass fiber yarns 2, 3 relative to the connection diameter R is in the range of 0.32 to 2.00.

A treated carbon fiber tensile cord for use in power transmission belts, hose, tires or other reinforced rubber products and the resulting product, which includes carbon fibers which are coated with a polymeric layer deposited and polymerized at atmospheric pressure in a plasma assisted chemical vapor deposition process. A suitable polymeric layer is compatible with the intended matrix which the cord will reinforce. For a rubber belt, the coating is compatible with the rubber composition of the belt body or an adhesion gum or adhesive such as RFL which surrounds the cord. For RFL/rubber systems and cast polyurethane elastomers, a suitable polymer is the APP reaction product of a vinyl carboxylic acid or an ester or amide thereof. Suitable carboxylic acids include acrylic acid and methacrylic acid. Various esters and amides of vinyl carboxylic acid are also suitable, such as 2-hydroxyethyl methacrylate, N-isobutoxymethyl acrylamide, and N-hydroxyethyl acrylamide.

Methods of additively manufacturing a part comprise dispensing a multi-part filament in three dimensions. The multi-part filament comprises an elongate filament body comprising a first body part extending longitudinally along the elongate filament body and comprising a first material that is configured to be cured responsive to a first cure condition, and a second body part extending longitudinally along the elongate filament body and comprising a second material that is configured to be cured responsive to a second cure condition that is different from the first cure condition. Methods also comprise concurrently with the dispensing, delivering curing energy corresponding to the first cure condition to impart a desired rigidity characteristic to the first body part to facilitate printing of self-supporting structures from the multi-part filament.

Multi-part filaments for additive manufacturing comprise an elongate filament body. The elongate filament body comprises a first body part extending longitudinally along the elongate filament body, and a second body part extending longitudinally along the elongate filament body. The first body part comprises a first material, and the second body part comprises a second material. One of the first body part and the second body part is more rigid than the other of the first body part and the second body part and is sufficiently rigid to print self-supporting structures from the multi-part filament.

A method of making a flexible pipe layer, which method comprises: commingling polymer filaments and carbon fibre filaments to form an intimate mixture, forming yarns of the commingled filaments, forming the yarns into a tape, and applying the tape to a pipe body to form a flexible pipe layer.

A sealing material composition which comprises sheet-like members containing expanded graphite, and which hardly causes the sheet-like members to be broken is provided. A sealing material composition 1 comprises: a stacked body 5; and a long surrounding body 6 which surrounds the stacked body. The stacked body has a plurality of sheet-like members 10 each of which is formed into a tape-like shape by expanded graphite. In the stacked body, the plurality of sheet-like members are stacked in a direction which intersects with the longitudinal direction of the surrounding body, and, in the plurality of sheet-like members, sheet-like members which are adjacent to each other in the stacking direction are disposed to be displaced from each other in the longitudinal direction of the surrounding body, in a relatively movable manner. The surrounding body allows the adjacent sheet-like members to be relatively moved in the longitudinal direction of the surrounding body, while maintaining the stacked state of the adjacent sheet-like members.

The present invention provides an outdoor armored fiber optical cable. By arranging water-blocking yarn parallelly to the optical fiber unit in armoring layer, or additionally arranging the water-blocking yarn in the reinforcing layer, ensure the cable no water leakage, and overall water resistance performance is enhanced. The armoring layer is a spiral steel tube structure, so that the fiber optical cable has excellent bending property, thus the present invention is particularly suitable for harsh outdoor environments.

The present invention relates to a twisted cord for constituting a core wire of a power-transmission belt, the twisted cord including a plurality of primary twisted yarns that are bundled and secondarily-twisted, in which when secondary twist is untwisted by 25 cm, a difference in length between the longest primary twisted yarn L and the shortest primary twisted yarn S among the plurality of primary twisted yarns is 1 to 10 mm.

A display device includes a display panel having a folding axis extending in a first direction; and a panel supporter disposed on a surface of the display panel. The panel supporter includes a first layer including a first base resin and first fiber yarns extending in the first direction and dispersed in the first base resin, a second layer disposed on the first layer, the second layer including a second base resin and second fiber yarns extending in a second direction intersecting the first direction and dispersed in the second base resin, and a third layer disposed on the second layer, the third layer including a third base resin and third fiber yarns extending in the first direction and dispersed in the third base resin.
