Abstract
The present invention provides an article, comprising: a fabric sheet; a curable resin coated onto the fabric sheet; and a plurality of microfiber fillers dispersed into the resin. The incorporation of microfiber fillers into the casting materials of the present invention adds substantially to the strength of the cured casting material, particularly when the fabric used therein is a non-fiberglass fabric, while not detracting from the handling properties of the uncured casting tape or bandage. The microfiber fillers useful in this invention are generally characterized as being short fibers having an aspect ratio greater than five to one. Blends of microfibers having different aspect ratios may be utilized in the casting tapes of the present invention. Preferred microfiber fillers or blends have an aspect ratio between 5:1 and 200:1, more preferably, the aspect ratio of the microfiber is between 5:1 and 50: 1, and most preferably, the aspect ratio of the microfiber is between 10:1 and 30:1.
