The magnetic fibrous polymeric oil filter for automotive was obtained by pneumoextrusion processing prepared from thermoplastic polymer(polyamide) containing magnetic particulate filler (Ba ferrite), and treated subsequently in a magnetic fields. Using an oil filter tester and particle quantifier, the dependence of filtrational charateristics of the magnetic oil filter on the parameters of mean pore sizes and magnetic properties were analyzed. Also experimental engine-bed test of oil filters was investigated. The magnetic fibrous polymeric filter was shown to possess a highly filtration efficiency in filtering the fine metal particles with increasing the magnetic force of filter element In this study, we knew that the efficiency of magnetic fibrous polymeric filter was dependent on the magnetic strength of the filter elements.<br/>

Wet-friction materials have been widely used for clutchs and brakes of auto motives over past several decades.<br/> In order to enhance its performance, its friction behaviour should be fully understood. It is, however, still not at hand and therefore an attempt was made to have some more understand. ing of friction behaviour of wet-friction materials.<br/> Measurements, of coefficient of friction were made with the variation of lubricants, lub.<br/> temperature, sliding velocity, and contact pressure.<br/> In addition, the effects of both the viscosity of lubricants and the porosity of materials on the coefficient of friction were also investigated.<br/> It can be concluded that the coefficient of friction is decreased as the cocentrations of the resin and inorganic fillers are increased, and it tends to decrease with the increase in the lubricant temperature and sliding velocity.
