Reinforcing Mechanism of Novel Aramid Pulp Short Fibre in Chloroprene Rubber Matrix

摘要

The reinforcing mechanism of novel aramid pulp (AP) short fibre in CR matrix has been discussed in this paper, and it has been shown that the reinforcing effects of AP depend mainly on the dispersing uniformity and openness of those ultra-fine short fibres of AP in CR matrix. By proper pretreating method, the dispersing uniformity and openness of ultra-fine AP short fibres with high specific area can be improved markedly, so the large reinforcing potential can bring into play adequately.
