“…Due to its heterogeneity, the amorphous carbon layer shells off along the fiber to various extents resulting in an increase of the fiber surface roughness. [13] The surface became rougher after treatment, i.e. the fibers possessed a larger surface area, which could contact with PI matrix and www.interscience.wiley.com/journal/sia thus formed more mechanical interlocking sites.…”

Pitch-based short carbon fibers (CFs) were treated by air oxidation and cryogenic nitrogen, respectively. Thereafter the treated and untreated CFs were incorporated into polyimide (PI) matrix to form composites. The CFs before and after treatment were examined by XPS and SEM.The flexural strength of the specimen was determined in a three-point test machine and the tribological properties of PI composites sliding against GCr15 steel rings were evaluated on an M-2000 model ring-on-block test rig. The results show that the surface of the treated CFs became rougher. Lots of active groups formed on the CF surface after air oxidation.The treatment can effectively improve the mechanical and tribological properties in their PI composites due to the enhanced fiber-matrix interfacial bonding.

“…The interaction of fibers and matrix is crucial for composite's performance in terms of strength, especially in short fiber reinforced composites [1][2][3][4]. Utilization of short fiber composites is wide spread reaching from kitchen spoons or bath tubs to secondary structures of cars, trains or even aircraft interior parts.…”
