Abstract: PROBLEM TO BE SOLVED: To provide a yarn dividing method and a yarn dividing device capable of stable production and getting the dividing filament yarn with less fluffs by detecting the retention of twist including the type (S twist, Z twist) with a censor and automatically adjusting the number of untwisting for reducing the workload of an operator, without causing an end breakage by a delaying operation especially when the operator handles the multiple devices. SOLUTION: This yarn dividing method for untwisting and dividing a doubled filament yarn detects the traveling position of the doubled filament yarn which is variable according to the variance of the number of twists based on the doubled filament yarn untwisting before the yarn dividing. The number of untwisting is controlled based on the detected position.

Abstract: PURPOSE:To reduce the weight of a joined part and to improve the durability by applying a graphite adhesive to the joining parts of composite materials each made of a carbon fiber reinforced carbonaceous material, winding a carbon fiber and carrying out heat treatment. CONSTITUTION:The graphite adhesive is applied to the joining parts 2 of composite materials 1, 1' each made of a carbon fiber reinforced carbonaceous material and the parts 2 are stuck to each other. The carbon fiber 3 is wound around the stuck part while applying the adhesive to fix the parts 2. Heat treatment is then carried out at a prescribed temp. to cure the adhesive.

Abstract: PURPOSE:To recover a carbon fiber from CFRP in high yields and to recycle the recovered carbon fiber. CONSTITUTION:A carbon fiber reinforced plastic is drydistilled to convert it into a carbide, this carbide is decomposed by oxydations in the oxygen concentration of 0.1 to 25 vol.% by heating to 300-1000 deg.C without causing its burning to recover a carbon fiber, and this fiber is recycled as a reclaimed carbon fiber. The obtained fiber can be utilized to reinforce a rubber, a thermoplastic resin or concrete or to improve its wear resistance.
