Plastic Bearings
. The bearing sleeve is then filament wound with a fiberglass epoxy shell. These bearings may carry static loads up to 50,000 psi. Another bearing material combines low friction and good wear resistance of filled PTFE with strength and thermal conductivity of bronze and steel-supporting structure

Thermoset Composites
reinforced with high-strength, high-modulus fibers of glass, carbon, aramid, or even boron, and usually laid up in layers to form an engineered component. More specifically, the term has come to apply principally to epoxy-resin-matrix materials reinforced with oriented, continuous fibers of carbon

Self-Healing spacecraft
. Possible self-healing concepts for polymer matrix composites. A photomicrograph shows the cross section of a four-layer composite that has been damaged and then was selfhealed. The healing epoxy resin was dyed so that it would illuminate under UV light. This clearly illustrates the extent

Rheology Benefits for Blending and Extrusion
Rheology is the science that studies the deformation and flow of materials, whether in liquid, melt, or solid form, in terms of the material's elasticity and viscosity. We test the following: liquids, pastes, gels, polymers, plastics, elastomers, epoxy, composites, adhesives, fillers, additives

More metal parts go to composites
reinforcement and matrix resin selection. Modulus values range from low 23,000 to ultrahigh 46,000 kpsi. The choice of matrix resin (polyimide, phenolic, or epoxy) is also a metric that lets designers tweak composite temperature and chemical resistance. Working temperatures for the various epoxy

Shot Peening FAQ's
is accomplished by mounting media in a epoxy or phenolic metallurgical mount. The specimen is ground approx halfway through the shot diameter. It is polished and micro-hardness tested on either a Knoop or Vickers scale and then converted to Rockwell C scale. What is better, cast steel or cut wire shot?. Cut

A dry subject
structure is impregnated with phenolic or epoxy resins, copper, babbitt, bronze, glass, or silver to give the desired strength, hardness, and wear properties. Common uses include pump bearings for water, gasoline, and solvents; conveyor and furnace bearings that operate at temperatures to 400 C
