摘要： The disclosure provides a process for manufacturing a tread molding element configured to mold at least a portion of a tire tread, the process comprising the steps of modeling a three-dimensional shape of a tread molding element through a modeling program that can be recognized by a 3D printer; providing one or more plastic compositions comprising one or more thermoplastic polymers having a melting point of at least 180° C.; forming a tread molding element by 3D printing from the one or more plastic compositions; and optionally annealing the tread molding element.

摘要： A shear band for a tire includes a first belt layer extending circumferentially around the tire, a second belt layer extending circumferentially around the tire, and a shear band radially interposed between the first belt layer and the second belt layer. The shear band includes a first reinforcing ply radially adjacent the first belt layer, a third reinforcing ply radially adjacent the second belt layer, and a second reinforcing ply radially interposed between the first reinforcing ply and the second reinforcing ply. The first reinforcing ply includes a first flattened, braided tube layer enclosed by a first rubber layer. The second reinforcing ply includes a second flattened, braided tube layer enclosed by a second rubber layer. The third reinforcing ply includes a third flattened, braided tube layer enclosed by a third rubber layer.

摘要： A method of making a non-pneumatic tire, the non-pneumatic tire comprising a ground contacting annular tread portion comprising a tread rubber composition, a shear band comprising a cord reinforced rubber composition and disposed radially inward of the tread portion, and at least one spoke disk disposed radially inward of the shear band; wherein the spoke disk has an outer ring, and an inner ring, and a first and second spoke extending radially between the outer ring and the inner ring, wherein the first and second spokes are connected at a joint; the method comprising the steps of: applying a curable adhesive as an interface between a radially outermost surface of the spoke disk and a radially innermost surface of the shear band in its uncured state; assembling the tread portion in an uncured state, the shear band in an uncured state, and the at least one spoke disk to form an pre-assembly; and curing the pre-assembly.

摘要： A shear band for a tire includes a first belt layer extending circumferentially around the tire, a second belt layer extending circumferentially around the tire, and a shear band coupon radially interposed between the first belt layer and the second belt layer. The shear band coupon includes a first reinforcing ply radially adjacent the first belt layer, a third reinforcing ply radially adjacent the second belt layer, and a second reinforcing ply radially interposed between the first reinforcing ply and the second reinforcing ply. The first reinforcing ply includes a first three dimensional layer enclosed by a first fabric layer. The second reinforcing ply includes a second three dimensional layer enclosed by a second fabric layer. The third reinforcing ply includes a third three dimensional layer enclosed by a third fabric layer.

摘要： A system determines average values for bending stiffness and shear rigidity of a shear band coupon. The system includes: application of multiple, different loads to a midpoint of a first span length of the shear band coupon; determining the deflection of the first span length at each of the multiple loads; application of the same multiple, different loads to a midpoint of a second longer span length of the shear band coupon; determining the deflection of the second span length at each of the multiple loads; determining the bending stiffness at each multiple load from the deflection of the first and second span lengths at each multiple load; averaging the bending stiffnesses at each load to determine an average overall bending stiffness of the shear band coupon; determining the shear rigidity at each multiple load from the deflection of the first and second span lengths at each multiple load; and averaging the shear rigidities at each load to determine an average overall shear rigidity of the shear band coupon.
