Abstract
Glass microfibers having diameters of less than one micron are useful in engineered plastics to achieve very smooth surfaces and thermal stability in composite parts. As made, glass microfibers are very bulky and intertwined making it impossible to meter and feed the material using conventional equipment. The processes used for chopping and milling coarser glass fibers to prepare them for engineered plastic composites are unsatisfactory for glass microfibers for various reasons. It has been discovered that flowable glass microfiber agglomerate products can be made by processing the microfiber in a muller mill or in a self impact mill.
