nowadays, soil reinforcement using polymer elements have been investigated by a number of researchers in order to increase the load capacity of soils. reinforcing soils using fibers is a method of soil improvement, which offers a homogenous mixture in combination with soils, regarding their tensile strength. this combination maintains pressure loading capacity and properties in mutual resistant...

A series of glass fiber-reinforced and rubber-toughened poly(ethylene terephthalate) hybrid composites were twin-screw extrusion compounded with varying total and relative concentrations of a reactive terpolymer of poly(ethylene-co-methyl acrylate-co-glycidyl methacrylate) (E-MA-GMA) as the elastomeric impact modifier (10-1520 wt.%) and short glass fiber – SGF (20-25-30 wt.%). Haake torque rheo...

Hydrogen bonded poly(acrylic acid) (PAA)/poly(ethylene oxide) (PEO) layer-by-layer assemblies are highly elastomeric, but more permeable than ionically bonded thin films. In order to expand the use of hydrogen-bonded assemblies to applications that require a better gas barrier, the effect of assembling pH on the oxygen permeability of PAA/PEO multilayer thin films was investigated. Altering the...

Nylon 6, 6 is regarded as tough and ductile materials since it exhibit high tensile elongation to break and high drop weight impact strengths. However, under conditions of stress concentration such as in the presence of sharp notches or cracks, polyamides exhibit brittle failure. This property, evaluated as notched Izod or Charpy impact tests, indicates that unmodified polyamides exhibit relati...

The subject is truly vast, far greater than will be encompassed in this paper which can be best deal with various examples. It should be realised that virtually any fairly solid substance may be called upon as a bearing material. It is easy to quote common examples which use rubies, wood, rubber, leather etc. as bearing materials and this diversity is only a microcosmic part of the range availa...
