METHOD AND DEVICE FOR MULTILAYER SHEAR STRIP REINFORCEMENT Russian patent published in 2013 - IPC B29D30/02 B60C7/22 B29C70/04 

FIELD: process engineering.

SUBSTANCE: invention relates to modification of shear strip of thickness H_ref and total quantity N_ref of reinforcement layers. Proposed method comprises steps of determination of vertical stiffness and (G_eff*A)_REF using H_ref and N_ref and selecting target magnitude H_TAKGET. Then, follows the step of calculation of (G_eff*A)_CALC using shear strip thickness H_TARGET and the step of increasing by 1 the total quantity of reinforcement layers in shear strip. Then calculated (G_eff*A)_CALC with compared with (G_eff*A)_REF and in case (G_eff*A)_CALC is smaller than (G_eff*A)_REF said step of increasing and said step of calculation are repeated unless ((G_eff*A)_CALC is not larger and approximately equal to (G_eff*A)_REF, total quantity of reinforcing layer becoming equal to N_Total. Then follows calculation of vertical stiffness using shear strip thickness H_TARGET said quantity N_total reinforcing layers obtained at comparison step, analysis of said vertical stiffness as-computed and that resulted from said determination. In case said vertical stiffness calculated at appropriate step exceeds that determined at appropriate step then proposed method includes the steps of displacement of at least one reinforcing layer between outer reinforcing layer and inner reinforcing layer to a new position in shear strip, closer to either outer or inner reinforcing layer. Said calculation and analysis steps are repeated unless vertical stiffness exceeds that obtained at said determination step or approximates thereto. Besides, this invention relates to shear strip.

EFFECT: improved properties of shear strip.
