    摘要： A method for reducing cure shrinkage of a thermoset resin includes forming a plurality of surface modified nanofibers. The surface modified nanofibers are formed by soaking nanofibers in an oxidizing acidic solvent. An oxidizing agent is added to the soaking nanofibers, thereby generating heat sufficient for at least one of in-situ oxidation and in-situ exfoliation of a subsurface of each of the nanofibers. Excess oxidizing agent and acidic solvent are removed from the nanofibers, which are then dried. The dried nanofibers have reduced surface hydrophobicity. The surface modified nanofibers are substantially uniformly dispersed into the thermoset resin. The surface modified nanofibers are adapted to reduce cure shrinkage of the thermoset resin during subsequent curing processes.

    摘要翻译： 降低热固性树脂固化收缩的方法包括形成多个表面改性纳米纤维。 表面改性的纳米纤维通过将纳米纤维浸入氧化性酸性溶剂中而形成。 向浸泡纳米纤维中加入氧化剂，从而产生足以用于每个纳米纤维的地下原位氧化和原位剥离中的至少一种的热量。 从纳米纤维中除去过量的氧化剂和酸性溶剂，然后干燥。 干燥的纳米纤维具有降低的表面疏水性。 表面改性的纳米纤维基本均匀地分散在热固性树脂中。 表面改性的纳米纤维适于在随后的固化过程中降低热固性树脂的固化收缩。

    摘要： A composite pressure vessel assembly method includes fitting an end portion of a tubular member into an annular slot formed in an end cap. Sealant may be in the annular slot. The end cap includes an annular groove in an exterior surface of the end cap body portion. A first material layer is formed on an exterior surface of the tubular member. The first material layer includes a first composite material including fibers oriented circumferentially to the tubular member. A second material layer is formed on the first material layer with a portion of the second material layer being disposed into the annular groove, and includes a second composite material including fibers oriented axially to the tubular member. A third material layer is formed adjacent the second material layer and in the annular groove, and includes a third composite material including fibers having an orientation circumferential to the tubular member.
