    Abstract: A diaphragm article includes an elastomer body reinforced with a pulp dispersion of polyaramid fibers. The elastomer has a material composition consisting of a silicon and/or fluoro-silicon polymer. The elastomer is blended with fiber to produce a heterogenous mixture. A compression molding process is used to fabricate the diaphragm, where a composition of aramid reinforced elastomer is employed as the preform structure. The diaphragm structure provides an increased strength and stiffness threshold. One diaphragm form includes fibers oriented generally orthogonally to the central pressure axis to provide improved radial stiffness. The diaphragm construction may be augmented with fabric reinforcement to provide further improvements in durability and performance.

    Abstract translation: 隔膜制品包括用聚芳酰胺纤维的纸浆分散体增强的弹性体。 弹性体具有由硅和/或氟 - 硅聚合物组成的材料组成。 将弹性体与纤维混合以产生异种混合物。 使用压缩成型工艺来制造隔膜,其中使用芳族聚酰胺增强弹性体的组合物作为预成型结构。 隔膜结构提供了增加的强度和刚度阈值。 一个膜片形式包括通常与中心压力轴线正交定向的纤维,以提供改善的径向刚度。 隔膜结构可以用织物加强件增强,以提供耐久性和性能的进一步改进。
