In this work, poly(para‐phenylene terephthalamide) (PPTA) paper sheets composed of PPTA fibers and PPTA fibrids filled with highly crystalline and high ratio of length to diameter potassium titanate whiskers (PTW) were investigated in view of possible employment as reinforcement and cost‐reducing materials. The morphological characteristics and the role of PPTA fibrids, the influence of PTW on the mechanical properties, interfacial adhesion, and thermal stability of the PPTA paper sheets were discussed. The results showed that the ductile, flexible and rough morphological characteristics of PPTA fibrids are helpful to improve the properties of PPTA paper. PTTA fibrids strongly wrapped PTW in the PPTA paper sheet was observed, which largely enhanced the retention rate of PTW and further improved the interfacial combination. The presence of PTW improved the mechanical properties and thermal stability of PPTA paper sheets. This research demonstrated the improvement of thermal and mechanical performances of PPTA paper sheets by incorporating of PTW, suggesting a significant cost‐reducing potential for the production of PPTA paper composite materials.
