Effect of plasma treatment on the stress-strain and the structure of locomotive wheel flanges;

By meons of Scanning electron microscope, X-ray photoelectron spectrum, Laser Raman spectrum and Dynamic capillary wicking analyses, the changes of the chemical structure and the wetting pro perly of the carbon fiber surface before and after plasma treatment were studied.

By Way of SEM observation for the carbon fiber surface and the determination of the mechanical properties of conjugate fibers,it is found that plasma treatment almost has no affection on the modulus of the carbon fiber,on the other hand, the fiber strength drops slightly with the increasing of the plasma power or with the extending of the treating time.

The polypropylene fiber wetting property is ameliorated obviously by the oxygen plasma treatment.

Effects of vacuum plasma-treated on surface properties of polylactic acid fiber;

Air low temperature plasma was employed to modify the surface of poly(phenylene sulfide)(PPS) fiber.

This paper discusses the surface etching of polyester thread through application of plasma and alkali deweighting to enbance the size adhesion to polyester thread and improve the abrasion-resistance of the sized polyester thread.
