    • A method of preparing a ply of composite material by applying an adhesive to a textile material comprising greige cords, so as to achieve an acceptable bond between the cords an elastomeric matrix, while not significantly altering the physical properties of the cords, is provided. The textile material comprises warp cords and weft cords; the weft cords are used to convey the warp cords through a heat setting oven without applying substantial tension to the warp cords, so as to not change their stress-strain properties. In the illustrated embodiment, the warp cords comprise aramid having a linear density of 500 to 3600 Denier and a twist multiplier of 5 to 8. The cords can be used in a crown reinforcing spirally wound overlay structure of a tire.
    • 提供了一种通过将粘合剂施加到包括格子帘布的纺织材料上来制备复合材料层的方法,以便在帘线之间实现可接受的粘合,同时不显着改变帘线的物理性质。 纺织材料包括经线和纬线; 纬线用于通过热定型炉传送经线,而不对经线施加显着的张力,以便不改变它们的应力 - 应变性质。 在所示的实施例中,经线包括线密度为500至3600旦尼尔和5至8的扭转乘数的芳族聚酰胺。帘线可用于轮胎的冠形加强螺旋卷绕的覆盖结构中。
