摘要： PURPOSE: To prevent the troubles in the handling of solidified pitch, by dividing the thermal polymerization process of pitch in two stages, heat-treating the pitch in the first thermal polymerization step until the pitch is about to form the mesophase, storing the product in liquid state, and supplying the liquid to a spinning apparatus furnished with a vacuum thermal polymerization apparatus.
CONSTITUTION: Pitch is made to react with a hydrogen-donative solvent, alcohol, phenol, etc., and the solvent is removed from the reaction product. The processed pitch is subjected to the thermal polymerization at 400W500°C to the state immediately before the formation of meso-phase, and is stored in liquid phase. The stored liquid pitch is supplied to a spinning apparatus furnished with a vacuum thermal polymerization apparatus, heated quickly to 400W550°C under reduced pressure to develop the meso-phase, and is spun as it is to obtain the objective pitch fiber.

摘要： PURPOSE: To improve adhesion to peripheral material by forming unevenness on the surface of a rod stock at the heat-curing of matrix resin by a method wherein the periphery of the uncured fiber reinforced plastic rod stock, which is made of one or more matrix resin-impregnated reinforced resin strands is covered with two kinds or more covering fibers having different factors of heat shrinkage from each other. CONSTITUTION: Uncured fiber reinforced plastic rod stock is made of one or more high strength and high elasticity inorganic or organic fiber strands impregnated with matrix resin consisting of thermoplastic resin or thermosetting resin. The uncured rod stock 1 is covered with two kinds or more covering fibers 2 and 3 having different factors of heat shrinkage from each other. Due to the difference between the factors of heat shrinkage of the respective covering fibers 2 and 3 developing at the thermal curing of the matrix resin, unevenness is formed at the surface of the rod stock 1. Thus, the fixing strength between the rod material and its peripheral material is enhanced by the improving action of adhesion through the interface of the uneven part, resulting in showing a high resistance against pulling-out.

摘要： PURPOSE:To obtain a carbon fiber having well aligned single filaments and free fluffs, by collecting the melt-spun pitch fiber in a reservior, infusibilizing the fiber in a perforated container under forced ventilation, and carbonizing or if necessary graphitizing the product under specific condition. CONSTITUTION:Melt-spun pitch fiber is taken off in a reservior without using a collecting agent by an air-stream take-off device, and infusibilized by heating in a container having ventilation holes in an oxygen-containing gas under forced ventilation. The obtained fiber is heated in an inert gas atmosphere until the breakage elongation of the fiber reaches >2.5%, preferably >3.0% to effect the primary carbonization. The carbonized fiber is transferred with a roll under tension through a carbonization furnace to effect the secondary carbonization or further the graphitization. The disturbance of the agglomerated state of the filaments can be prevented by this process.
