INFLUENCE OF HOT-PRESSING TEMPERATURE ON THE FORMATION OF ARAMID PAPER.

Meta-aramid fibrid is prepared by precipitation, and aramid fibers are mixed with meta-aramid fibrid to make aramid paper by hot-pressing technology. Meta- -aramid fibrid possesses an excellent binding and adhesive properties with the aramid short fibers, yielding high mechanical properties of the aramid paper. The effects of hot-pressing temperature on the mechanical property of metaaramid paper are mainly discussed. Experimental results indicate that the mechanical property of aramid paper increases first and then decreases with the increase of hot-pressing temperature. The fundamental cause of this phenomenon is elucidated, and the aramid paper reaches its maximal mechanical property when the hot pressing temperature is 300 °C.. [ABSTRACT FROM AUTHOR]
