Interface/Interphase Studies in Epoxy Matrix Composites

Optimization of material parameters for development of polyetherimide composites

“…Since in recent studies Rattan et al [4] reported that in low amplitude oscillation wear (LAOW) mode satin weave composite resulted in the highest wear followed by twill (2 × 2) and plain for PEI composites with 55% CF (vol), it was proposed to continue the work with some more weaves of CF. Moreover, since it is reported that plasma treatment to the fibers improves fiber-matrix adhesion largely by introducing polar or excited groups that can form strong covalent bonds between the fiber and matrix and also increase mechanical interlocks between them by roughening the surface of fibers [5][6][7][8][9][10], it was decided to explore the potential of modified technique (cold remote nitrogen plasma with traces of oxygen) and to examine its effect on the strength and tribo-performance of composite.…”

Effects of Plasma Treatment on Mechanical Properties of Jute Fibers and Their Composites with Polypropylene

“…Various modification methods have been suggested. [5][6][7] They include electrochemical vapor deposition, 8) solution method, 9,10 monomer or oligomer chemicals, 11,12 plasma etching [13][14][15][16][17][18] and plasma polymerization coating method. [19][20][21][22][23][24][25] When the surface of natural fibers are modified by chemical methods, the interfacial properties can be efficiently improved, but the process needs somewhat complex steps of treatments including removal and recycling of the chemicals leading to additional process cost.…”

Analytical investigation of plasma-treated carbon fibres

“…The time of exposure was varied up to 90 min in order to obtain different oxidation degrees of the fibres. It has been shown that this plasma technique provides increased levels of surface activity with functionalisation of the basal plane sites at the fibre surface [6].…”
