(materials)
Short, linear crystals of alumina which have a strength of up to 200,000 pounds per square inch (1.38 gigapascals); used in plastics as a filler to improve heat resistance and dielectric properties. Also known as sapphire whiskers.

The tips of the fine alumina fibers have a superior grinding force that improves surface finish faster than other tools.
Finally, both of the as-obtained alumina fibers were used to adsorb Congo red from water solution.

As shown in Figure 4(d), the alumina fibers are relatively small in diameter than its AACH precursors, and the microfibers were comprised of worm-like mesopores with the pore size about 10 nm (shown in Figure 4(f)) that is probably induced by shrinkage during calcination accompanied by release of [H.sub.2]O and decomposition of PEG and AACH precursor.
To that end, researchers at Touchstone Research Laboratory, Ltd., Triadelphia, WV, developed MetPreg, a fiber-reinforced aluminum material system that consists of continuous, high-strength alumina fibers in a prepreg tape that can be consolidated into shapes using conventional composite processing techniques.
