In the study, Kevlar fiber and NBKP were used to mark up the composite laminate base paper by four ratio which are 20:80, 50:50, 70:30, 100:0, then add the 1.0%, 1.5%, 2.0% of APAM into the paper, respectively. By testing the physical properties of paper and use microscope to watch the formation in fiber, to find the best conditions of marking paper. The results indicated that the Kevlar: NBKP is 50:50, have better machine strength, and the APAM is 2.0%, the base paper have better physical properties.
