摘　　要：研究纤维状海泡石的结构及其对海泡石／氟橡胶复合材料耐磨性能的影响。结果表明：海泡石纤维束直径集中在100-200nm，长度为1～5μm，聚集体内孔径为3-100nm；随着纤维状海泡石用量的增大，复合材料的100％定伸应力增大，拉伸强度先增大后减小，拉断伸长率下降；当海泡石用量为15份时，复合材料表现出良好的耐磨性能。The structure of fibrous sepiolite and the influence of fibrous sepiolite on the abrasion resistance of sepiolite/fluororubber composite were investigated. The results showed that, the diameter and length of sepiolite fibrous bundle mostly were 100-200 nm and 1-5 μn, respectively, and the pore diameter of the bundle and aggregation was 3-100 nm. As the addition level of fibrous sepiolite increased, the modulus at 100% elongation of the composite increased, the tensile strength increased at first and then decreased, the elongation at break decreased. The composite showed good abrasion resistance when the addition level of fibrous sepiolite was 15 phr.
