Abstract: Disclosed herein is a non-pneumatic tire with a reinforcing member. The non-pneumatic tire includes a tread part which comes into contact with the ground, a rim part which is coupled to an axle, an outer annular band part which forms an interface with an inner surface of the tread part, an inner annular band part which forms an interface with the rim part, a spoke part which is disposed between the outer annular band part and the inner annular band part and functions as a support, a connector which connects spokes of the spoke part to each other, and a reinforcing member which has a plate wire structure. The non-pneumatic tire can effectively and sufficiently withstand the weight of a vehicle. Further, the performance of the tire is balanced with respect to the contact area, the displacement extent and the resistance to rolling.

Abstract: Provided are a rubber composition for tire tread including 100 parts by weight of a raw material rubber that includes 20 parts by 80 parts by weight of a first solution polymerized styrene-butadiene rubber (SBR1) having a styrene content of 15% to 25% by weight and a vinyl content in the butadiene of 60% to 65% by weight and produced by a batch method; and 60 parts to 90 parts by weight of a silica having a specific surface area measured by nitrogen adsorption of 155 m2/g to 185 m2/g and a CTAB value of 150 m2/g to 170 m2/g, and a tire producing using the rubber composition. The rubber composition for tire tread has excellent processability in an unvulcanized state, and can improve all of the braking performance on wet road surfaces, the braking performance on icy road surfaces, and the low fuel consumption performance.

Abstract: Disclosed is a bead reinforcing structure for a heavy duty tire having a bead in which a carcass is turned up to surround a bead core. The bead reinforcing structure includes a carcass, and an inside steel chafer having a first predetermined inclination angle and an outside steel chafer having a second predetermined inclination angle. The inside and outside steel chafers are disposed inside and outside the carcass, respectively, thereby reinforcing the bead from the inside and outside of the carcass.

Abstract: Provided is a pneumatic tire which can fundamentally prevent the phenomenon in which cracks are generated in the bottoms of grooves and the areas where the side walls of blocks meet the bottoms of grooves, can suppress irregular abrasion of the tread, can enhance the overall rigidity of the tread, and can also enhance the drainage performance. The pneumatic tire of the invention includes a tread, side walls and bead sections, with a large number of blocks compartmentalized by grooves being formed on the surface of the tread, and also includes reinforcing ribs that are positioned inside a groove and have their lower parts joined with the bottom of the groove, with one lateral surface of a reinforcing rib and one side wall of the groove being in contact.

Abstract: Disclosed herein is a method of designing spokes of a non-pneumatic tire which randomly arranges spokes around a circumference to optimize noise dispersion. The method of designing spokes of a non-pneumatic tire includes placing a plurality of spokes (2) holding and supporting a tread (1) to be radially installed around a circumference of the tire on a circular spoke support (3) under the tread (1) to be in contact with the ground, wherein the spokes (2) are arranged at three angles on the circular spoke support (3) around the circumference of the tire, the three angles being divided into a small angle (a), a medium angle (b) and a large angle (c), and the spokes (2) are arranged at irregular angles under a condition that a ratio (q) of the large angle (c) to the small angle (a) is greater than a ratio (p) of the medium angle (b) to the small angle (a).

Abstract: Disclosed are a separator for a fuel cell that improves power characteristics of the fuel cell, and a fuel cell including the same. The separator includes a plurality of current-carrying units, and an insulating unit interposed between the current-carrying units, wherein each current-carrying unit includes a first polymer matrix in which carbon-based particles are dispersed, and the insulating unit includes a second polymer matrix in which insulating inorganic particles are dispersed. The separator for fuel cells includes an insulating unit that exhibits low gas permeability and superior electrical insulation property, and the current-carrying unit that exhibits superior strength characteristics and conductivity, thus increasing voltage generated per one cell and considerably increasing a power generated per a constant area, when applied to the fuel cells.

Abstract: The present disclosure provides a non-pneumatic tire. The non-pneumatic tire includes an outer cylindrical section having a tire tread; an inner cylindrical section connected to an axle of a vehicle; and a noise and vibration prevention spoke unit connecting the outer cylindrical section to the inner cylindrical section. The spoke unit is continuously supported by a road surface during vehicle driving, thereby reducing noise and vibration. In the non-pneumatic tire, the spoke blades are arranged at an angle, so that the spoke unit is continuously supported by a road surface during vehicle driving, thereby enabling reduction of noise and vibration while improving ride comfort. In addition, the non-pneumatic tire allows a designer to set lateral forces, as needed, as opposed to a conventional non-pneumatic tire, thereby enabling control of a leaning phenomenon caused by road structure.

Abstract: Provided is a high-performance pneumatic radial tire for passenger cars which uses a hybrid cord composed of an aramid cord and a Nylon 66 cord having different twist counts for the first twist and different twist counts for the second twist, as a reinforcing belt, and thereby has improved high speed durability and steering stability.

Abstract: Disclosed is a truck/bus tire that has an improved decoupling groove capable of suppressing unbalanced wear of a shoulder rib and preventing side chipping of a tread, and that has enhanced durability of a belt. The tire has a decoupling groove formed between an outermost rib and a tread lateral side. An offset structure is provided by cutting off a portion around a start point where a virtual line extending from a distal end of the outermost rib of the tread intersects a virtual line extending from the tread lateral side. A side of the outermost rib is parallel to the tread lateral side and the cut-off portion is formed with a “<”-shaped groove. A sacrifice rib protruding from the “<”-shaped groove is formed coplanar with the start point located on the virtual line extending from the tread lateral side.
