Experimental 2.1 Materials and the preparation process The filler used in this study was Kevlar pulp (Type 1F538, density, 1.41 g/mm3, diameter, 14 um, average length, 1.7 mm, manufactured by DuPont Inc., Brownslane, KY, USA).
The applied load was mainly borne by Kevlar fiber and the wear resistance of the materials has been greatly improved by incorporating Kevlar pulp. 4.
Conclusion The incorporation of Kevlar pulp into PEI can increase the tensile properties of the composite but either increase or decrease friction and wear properties of the materials, depending on the volume fraction of Kevlar.
