摘  要：芳綸紙蜂窩片切后的端面會(huì)有纖維裸露，放置在環(huán)境中會(huì)造成蜂窩厚度變化，影響使用的精度。該文采用不同溫度（90、120、150 ℃）對(duì)自制芳綸紙蜂窩進(jìn)行烘干，研究烘干溫度對(duì)不同孔格尺寸、紙張厚度蜂窩高度的影響。通過分析紙張的熱收縮和環(huán)境處理后蜂窩高度方向變化探究尺寸收縮的原因。

Abstract： After the aramid paper honeycomb sheet is cut， there will be fibers exposed on the end face， and the honeycomb thickness will change when placed in the environment， which will affect the accuracy of use. In this paper， the honeycomb of self-made aramid paper was dried at different temperatures （90， 120， 150 ℃）， and the effects of drying temperature on the honeycomb height of different hole size and paper thickness were studied. The reason of size shrinkage is explored by analyzing the heat shrinkage of paper and the change of honeycomb height direction after environmental treatment.

Keywords： aramid paper; honeycomb; thickness; temperature; heat treatment
