摘要： A process using ultraviolet light having a wavelength of 160 to 500 nanometers without higher wavelengths and a high intensity between about 1 and 40 watts/cm2 to surface treat a carbon containing fiber is described. The treated fiber contains an enhanced amount of oxygen on the surface which significantly improves the bondability of the fiber in composites.

摘要： A method and apparatus for aligning discontinuous fibers (F 101, 212) is described. A feeder apparatus (20, 120, 220, 220A) is used to align the fibers in a horizontal plane for feeding to the aligning apparatus (40, 140, 240, 240A) providing an electrical (E) field to orient the fibers in one preselected direction. A support or conveyor (70, 170, 270) receives the aligned fibers. The method and apparatus provides composite products having improved physical properties because of the alignment. The fibers can be of different lengths and a mixture of different types to make composites with controlled microstructure and properties. The composite materials can be in the form of non-woven, discontinuous fiber reinforced thermoplastic stampable sheets with controlled fiber orientation distribution. The composites are useful for a variety of goods.

摘要： A lubricant composition is disclosed that includes (a) a machining oil and (b) an exfoliated graphite nanoparticle (EGN) material stably dispersed in the machining oil. The lubricant composition is a stable suspension and is suitable for use as a liquid lubricant in a Minimum Quantity Lubrication (MQL) process. In the MQL process, the lubricant composition is applied/transferred to a worksite in the form of a mist. The presence of the EGN material in the lubricant composition provides high-temperature stability and lubricity under MQL conditions. A very small amount is transferred especially at high cutting speeds where the mist of the machining oil evaporates, but the EGN material remains on the surface to provide lubricity. Any operation involving machining can benefit from this lubricant composition. The method provides important benefits of reducing chipping on cutting tools and providing the additional lubricity especially when the cutting become very hot and thus extending tool life.
