摘要： The present invention includes a carbon fiber prepreg layer formed by impregnating thermosetting resin on a fiber body in which carbon fibers are arranged in a unidirection; and a heat resistance reinforcement layer including an aramid fiber prepreg formed by impregnating thermosetting resin on a fiber body in which aramid fibers are arranged in a unidirection or an aramid fabric prepreg formed by impregnating thermosetting resin on an aramid fabric. According to the present invention, since the aramid fiber or fabric having excellent shockproof properties is included in the heat resistance reinforcement layer, an electrolyte is effectively prevented from being leaked due to the collapse of the internal layer by an external shock, so that excellent insulating properties may be achieved. In addition, since the present invention uses a carbon fiber prepreg instead of metal thin layers, used in the prior art, to prevent the permeation of water vapor gas and leakage of an electrolyte, the weight is reduced and the flexibility is improved, so that an internal layer is effectively prevented from being collapsed due to an external shock, thereby improving insulating properties and lightweight properties.
摘要翻译：本发明包括通过将热固性树脂浸渍在碳纤维单向布置的纤维体上形成的碳纤维预浸料层，以及耐热增强层，其包括通过将热固性树脂浸渍在芳族聚酰胺纤维布置在芳族聚酰胺织物上而形成的芳族聚酰胺纤维布置在芳族聚酰胺织物预浸料中而形成的芳香族聚酰胺纤维预浸料。根据本发明，由于具有优异的防震性的芳族聚酰胺纤维或织物被包括在耐热性增强层中，所以可以有效地防止由于外部冲击而导致内层塌陷而导致的电解液泄漏，从而绝缘性优异性能可以实现。此外，由于本发明使用碳纤维预浸料代替现有技术中使用的金属薄层，以防止水蒸汽气体的渗透和电解液的泄漏，因此重量减轻并且柔性得到改善，因此有效防止内层由于外部冲击而被塌缩，从而提高绝缘性能和轻质性。

摘要： 본발명은섬유기재의적어도일면위에결정화도가 1~20%인열가소성수지필름을적층한다음, 열가소성수지필름의융점보다높은온도로가열한후 가압하여열가소성프리프레그를제조한다. 본발명은섬유기재내에열가소성수지를균일하게함침시켜고품질의열가소성프리프레그를제조할수 있고, 소량의열가소성수지필름사용으로재활용이가능하며성형시경화싸이클이짧고, 가압시에도섬유기재내에함침되는열가소성수지의결정화도가낮기때문에섬유기재내섬유배열이임의로변형되지않아성형품의강성을높을수 있고박판화도가능하다. 상기방법으로제조된본 발명의열가소성프리프레그는섬유기재내에열가소성수지가균일하게함침되어단위면적당중량변동율이낮다.
