The invention relates to an aircraft radial tyre having a radial carcass reinforcement (1) comprising a plurality of carcass plies consisting of textile reinforcing elements oriented substantially radially (i.e. Forming an angle of between 75 DEG and 105 DEG with the circumferential direction), the radial reinforcing elements of the carcass ply are composite cords comprising at least one aramid yarn, the breaking strength of which is FR measured according to standard D885/D885M-10A (2014), and these elements have a deformation of at least 4.6% for an applied force equal to FR/4. The reinforcing elements have a toughness of at least 80 daN/mm2 and at least one aramid yarn has a linear density of no more than 210 tex. The thickness adjusted according to the forming radius of the carcass ply remains constant throughout the tire.
本发明涉及一种具有径向胎体增强件(1)的飞机子午线轮胎,所述径向胎体增强件(1)包括多个胎体帘布层,所述胎体帘布层由基本上沿径向定向(即与周向方向形成75°至105°之间的角度)的织物增强元件构成,所述胎体帘布层的径向增强元件是包括至少一根芳族聚酰胺纱线的复合帘线,所述复合帘线的断裂强度是根据标准D885/D885M–10A(2014)测量的FR,并且这些元件对于等于FR/4的施加力具有至少4.6%的变形。这些增强元件的韧度至少为80daN/mm2,并且至少一根芳族聚酰胺纱线的线密度不超过210tex。根据胎体帘布层的成型半径进行调整的厚度在整个轮胎上保持恒定。
