Fibers
, typically 1 to 4 microns in diameter. Because glass fibers have a large surface area in proportion to volume (a -in.-diameter bead of glass is stretched into over 97 miles of fiber) surface conditions of the fiber have a strong influence on its strength and behavior. Most glass-reinforced products

Reinforced Plastics Make Metals Look Weak
1,000 to 50,000 parts annually. CFRTP BASICS. Fiber-reinforced thermo-plastics are widely used in injection molding. The vast majority of these products use short or chopped fibers. These fibers generally measure less than 0.25 in. and will randomly orient themselves during molding. Typical injection

Thermoset Composites
that of glass-reinforced systems, particularly in alkaline environments. Like most rigid materials, however, carbon-fiber composites are relatively brittle. The composites have no yield behavior, and resistance to impact is low. Thermal characteristics of carbon fibers are different from those

Sewing lessons for aerospace engineers
lighter. In aerospace, weight certainly matters. Every pound shaved away brings higher payload capacities or lower fuel costs. About a quarter of the Airbus A380 structure, for example, will be lightweight carbon-fiber-reinforced plastics (CFRPs). The parts include the central wing box, wing flaps

Grille guard garners top automotive accolade
substructure that is then covered with a rubber bumper or plastic beauty cover. In contrast, the insert-molded grille uses a PP composite made by the direct in-line long-fiber-reinforced (DLFT) process and transfer-compression molding. Cycle times for this single-step-operation are about 2 min

Give glue a go
cross-bonding plastics to metals or composites. Composites (including sheetmolding compounds, fiberglass, fiber-reinforced plastics, pultrusion, and carbon-fiber substrates): Urethanes and acrylics are well known for their composite bonding abilities. They need little or no surface prep, are easy
