Abstract: Provided is a composition containing fine fibers for forming a coating film. The composition has excellent spreadability and provides a coating film with excellent uniformity by application to a skin. A composition for forming a coating film comprising the following components (a) and (b): (a) a fiber at 0.5 mass % or more and 10 mass % or less based on the total composition for forming a coating film. The fiber has an average fiber diameter of 0.1 ?m or more and 7 ?m or less and an aspect ratio [(average fiber length)/(average fiber diameter)] of 8 or more and 300 or less; and (b) a volatile component at 15 mass % or more and 90 mass % or less based on the total composition for forming a coating film. The [(average fiber diameter)2/(fiber content)] (?m2/mass %) of the composition is 0.005 or more and 7 or less, and the total content of the component (a) and the component (b) is 97 mass % or less.

Abstract: A method of continuously draw-molding a fiber reinforced plastic rod formed with a spiral groove includes the steps of arranging in parallel a plurality of reinforcing fibers under tension, impregnating an unhardened thermosetting resin in the reinforcing fibers with tension being applied to the reinforcing fibers, winding a tape having a resin impregnable property and an expandible and contractible property around a fiber bundle composed of the thermosetting resin impregnated reinforcing fibers in a spiral fashion with a winding angle being substantially equal to an angle of the spiral groove with respect to an axial direction of a rod to be molded, passing the fiber bundle with the wound tape in a heating mold provided with a hole having a cross section substantially equal to that of the rod to be molded to heat and harden the thermosetting resin, and taking up the tape thereafter.

Abstract: A fixing device for a tensioning member of a prestressed concrete may unimly act holding force for the tensioning member on the overall peripheral surface of the tensioning member mating with the wedge. The device includes a stationary grip through which the tensioning member extends, a wedge press fitted to the grip with holding the tensioning member for fixing the tensioning member relative to the grip under a given tension, and a buffer member disposed between the tensioning member and the wedge, the buffer member having both elasticity and plasticity.

Abstract: A fiber reinforced plastic reinforcement for concrete structure comprises a core made of a fiber reinforced plastic material composed of a matrix resin and reinforcing fiber, uneven profile portion integrally formed on the peripheral surface portion of the core having alternately arranged first higher portions and second lower portions, and the reinforcing fiber extending in series across the core and the uneven profile portion.
