The invention relates to an aircraft radial tyre having a radial carcass reinforcement (1) comprising a plurality of carcass plies (11, 12, 13, 14) consisting of textile reinforcement elements oriented substantially in the radial 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 the standard D885/D885M-10A (2014), these elements having a deformation of at least 4.6% and at most 6.5% when a force of FR/4 is applied. The reinforcing elements have a toughness of at least 80 daN/mm2 and at least one aramid yarn has a linear density of more than 210 tex.
本发明涉及一种飞机子午线轮胎,其具有径向胎体增强件(1),所述径向胎体增强件(1)包括多个由织物增强元件组成的胎体帘布层(11、12、13、14),所述织物增强元件基本上沿径向定向,亦即与周向方向(XX’)形成75°至105°之间的角度,所述胎体帘布层的径向增强元件是包括至少一根芳纶纱线的复合帘线,所述复合帘线的断裂强度是根据标准D885/D885M‑10A(2014)测量的FR,这些元件在施加FR/4的力时具有至少4.6%且至多6.5%的变形。这些增强元件的韧度为至少80daN/mm2,并且至少一根芳纶纱线的线密度超过210tex。
