    Abstract: A heat-resistant fibrous paper which is formed mainly from short fibers made of a heat-resistant organic polymer, short fibers made of an unstretched or lowly stretched para-aromatic polyamide, and an organic resin binder and/or fibrids made of a heat-resistant organic polymer, wherein the amount of the short fibers is 45 to 97 wt.% based on the whole paper, the amount of the organic resin binder and/or the fibrids is 3 to 55 wt.%, and the organic resin binder has been cured and/or the short fibers of an unstretched or lowly stretched para-aromatic polyamide and the fibrids were partly softened and/or deformed and melted to make them serve as a binder. This heat-resistant fibrous paper is excellent in heat resistance, thermal dimensional stability, interlaminar peel strength, electrical insulating properties in a high-humidity atmosphere, etc. and can be satisfactorily impregnated with a resin despite its high bulk density. It is especially suitable for use as a substrate for electrical insulating materials or a substrate for layered products for electrical circuits.

    Abstract translation: 主要由耐热有机聚合物制成的短纤维形成的耐热纤维纸,由未拉伸或低拉伸的对位芳族聚酰胺制成的短纤维,和由热塑性聚酯制成的有机树脂粘合剂和/或纤条体, 其中短纤维的量相对于全纸为45〜97重量%,有机树脂粘合剂和/或纤条体的量为3〜55重量%,有机树脂粘合剂为 已经固化和/或未拉伸或低拉伸的对位芳族聚酰胺的短纤维,并且纤条体被部分软化和/或变形并熔化,使得它们用作粘合剂。 该耐热性纤维纸的高体积密度,耐热性,热尺寸稳定性,层间剥离强度,高温环境下的电绝缘性等优异,可以令人满意地浸渍树脂。 特别适用于电绝缘材料的基板或用于电路层叠产品的基板。
