摘要:
The present invention aims at providing an inorganic fiber molded body that is excellent in scale resistance, thermal shock resistance and mechanical shock resistance, and prevented from suffering from shrinkage when used under high-temperature heating conditions. The inorganic fiber molded body of the present invention is produced by impregnating a needle blanket of inorganic fibers with a liquid material of a precursor of a spinel-based compound represented by the general formula: Mg x Al y O 4 wherein an atomic ratio (y/x) is not less than 2 (y/x ≥ 2); drying the thus impregnated needle blanket; and firing the dried needle blanket to convert the precursor into an oxide thereof.

摘要:
The invention is directed to a process for preparing a blended tow of thermoplastic and reinforcing fibers. The process of the invention includes the steps of forming a substantially planar spaced array of thermoplastic multifilament yarns (12) and superimposing the spaced array (40) of separate yarns (12) onto a spread tow (62) of reinforcing fibers. The resulting planar mixed yarn is then gathered into a tow (135) having a non-uniform distribution of thermoplastic fibers throughout the tow. The tow (135) is useful in forming fiber-reinforced composite articles by shaping the tow into a desired form and then heating the shaped tow to melt the thermoplastic fibers which, in turn, form a plastic matrix which is reinforced by the reinforcing fibers.
