Abstract

Sized short alumina-based inorganic oxide fiber comprises, based on the total weight of the sized short alumina-based inorganic oxide fiber: from 0.1 to 15 percent by weight of a size resin comprising a polyamide; and from 85 to 99.9 percent by weight of short alumina-based inorganic oxide fiber. Methods of making the sized short alumina-based inorganic oxide fiber and compositions comprising the sized short alumina-based inorganic oxide fiber in a polymeric matrix are also disclosed.

Description

technical field [0001] The present disclosure broadly relates to sized inorganic oxide fibers, fiber composites, and methods of making the same. Background technique [0002] High modulus, high strength inorganic oxide fibers are used to prepare many high performance polymer composites. There are generally two types of polymer composites: short fiber reinforced composites and continuous fiber reinforced composites. Short fiber reinforced compounds often contain thermoplastics and are processed by extrusion. Continuous fiber reinforced composites often comprise thermosetting resins, where the fibers are usually pre-twisted and impregnated with resin to produce a so-called "prepreg", which is then spun and cured into a specific shape. Such composites are typically produced by extrusion compounding processes where pre-chopped staple fibers are added to the extruder through a feed port. To facilitate fiber addition, fiber binders (ie, fiber glue) are used to hold the staple f...
