    摘要: The present invention relates to meta- and para-aramid pulp for use as reinforcement material in products such as seals and friction materials. The pulp comprises (a) fibril free meta-aramid particles, (b) irregularly shaped, para-aramid fibrous structures, and (c) water, whereby the para-aramid fibrous structures contact and are wrapped partially around at least some of the meta-aramid particles. The invention further relates to processes for making such aramid pulp.
