    • Use of a resin system for making a composite material in a liquid moulding process. The resin system comprises an epoxy component and at least one curing agent, and at least 35 wt. % of the epoxy component is one or more naphthalene based epoxy resin. There is also provided a cured composite material, and a method of making the cured composite material in a liquid moulding process which comprises placing fibre reinforcement and the resin system in a mould and curing. The resin system and the methods of making a cured composite material are particularly applicable to liquid moulding processed such as resin trans moulding (RTM), vacuum assisted resin transfer moulding (VARTM), Seeman composite resin infusion moulding (SCRIMP), resin infusion under flexible tooling (RIFT), and liquid resin infusion (LRI).
    • 在液体成型工艺中使用用于制备复合材料的树脂体系。 树脂体系包含环氧组分和至少一种固化剂,并且至少35wt。 %的环氧组分是一种或多种萘基环氧树脂。 还提供了固化的复合材料,以及使固化的复合材料成为液态成型工艺的方法,该方法包括将纤维增强物和树脂体系放置在模具中并固化。 树脂体系和固化复合材料的制备方法特别适用于树脂反式成型(RTM),真空辅助树脂传递模塑(VARTM),塞曼复合树脂浸渍成型(SCRIMP),柔性树脂注入 加工(RIFT)和液体树脂输液(LRI)。

    • An emergency buoyancy system mounted to a vessel includes a depth sensor to sense a predetermined maximum depth, and an actuator actuated by the depth sensor. The actuator, upon actuation, opens a membrane between tanks, each holding one of a pair of gas producing chemicals. The gas producing chemicals, preferably bicarbonate of soda and vinegar, mix together to produce carbon dioxide. The carbon dioxide fills a plurality of balloons, thereby providing buoyancy to the vessel to which the balloons are attached.
    • 安装在容器上的紧急浮力系统包括用于感测预定最大深度的深度传感器和由深度传感器致动的致动器。 致动器在致动时在罐之间打开膜,每个保持一对产生气体的化学品之一。 产生气体的化学品,优选苏打水和醋的碳酸氢盐,混合在一起产生二氧化碳。 二氧化碳填充多个气球,从而向气囊附着的容器提供浮力。
