    Abstract: PURPOSE:To prevent the broken pieces of the blade from being scattered to distant places by arranging linear materials or the like along the lenghwise direction in the cavity of the windmill blade. CONSTITUTION:A plurality of cores 2A, 2B, made by expansion molding of urethane and having the substantially same section as the section of the cavity, are provided in the cavity of the windmill blade 1 with equal intervals. A rope 3, penetrating through the cores and stretched in the lengthwise direction of the windmill blade 1, is bound by a thread 5 onto the surface of stiffening plates 4 arranged at both end surfaces of the windmill blade 1 and both binding parts are adhered by resin. The rope 3 is provided with a flexibility, meeting to the centrifugal force due to the rotation and the deflection due to the air force caused by the rotation, as well as a strength capable of withstanding against a scattering force in case the windmill blade is broken.

CONSTITUTION:A thermoplastic resin compsn. comprises the following components [A] to [C]. The component [A] is a thermoplastic styrene resin. The component, [B] is a modified polyolefin resin prepd. by grafting a polyolefin resin with an alpha,beta-unsatd. carboxylic acid or a deriv. thereof, the amt. of which is 0.1 to 15wt.% based on the polyolefin resin. The component [C] is either a modified graft copolymer prepd. by graft copolymn. of a diene rubber with a monomer mixture of an epoxy group-contg. vinyl monomer and other copolymerizable monomer, or a modified graft copolymer compsn. comprising the above-mentioned modified graft copolymer and a copolymer of the remaining monomers. The blending ratio is such that [A]/[B]=-5/95 to 95/5 (wt. ratio) and the amt. of the component [C] is 1-100 pts.wt. per 100 pts.wt. in total of the components [A] and [B].

    Abstract: PURPOSE:To provide the unit for making the fibers flame-resistant or infusibilization which can increase the infusibilization rate without giving any physical damage to the precursor fibers. CONSTITUTION:In the infusibliization unit where two groups of outer rollers 12a through 12c and 13a through 13c are arranged on both sides of the infusibilization furnace 20 in the longitudinal direction so that the precursor fibers 101 can be passed through and returned several times, and solid thermal medium particles 30 piled up in the furnace 20 are fluidized with a heated oxidative gas to effect continuous heat treatment of the precursor fibers 101 in the fluidized thermal medium, at least one of a porous body 31 of wavy cross section is set between each stage of the yarn path. On the way the bubbles in the fluidized layer 4 go up, they collide to the porous body 31 to change their vectors and the bubbles burst into uniform fine bubbles.
