    摘要： A fiber reinforced plastic pipe comprising a cylindrical inner layer formed by winding a prepreg sheet containing a thermosetting resin as a matrix and an outer layer formed by winding a thermoplastic resin sheet or tape around the inner layer, said inner and outer layers being heat cured and thermocompression bonded in one united body; and a process for manufacturing the fiber reinforced plastic pipe. When the fiber reinforced plastic pipe is manufactured, the thermosetting resin is used for forming the inner layer and the thermoplastic resin is used for forming the outer layer. Moreover, a metal coat can be firmly bonded to the surface of the outer layer. Hence, a fiber reinforced plastic pipe prominently improved in impact resistance, abrasion resistance and lightweight properties can be provided.

    摘要： An optically isotropic pitch can be obtained by a two-stage heat-treatment which combines a heat treatment with air-blowing under normal pressure with a heat treatment with air-blowing under a reduced pressure. Such a pitch is suitable for using as a raw material for producing carbon fibers or activated fibers.

    摘要： A process for providing activated carbon fibers consisting of optically anisotropic components and optically isotropic components by spinning a pitch into fibers, and infusibilizing the resulting fibers, followed by an activation treatment. The pitch for spinning is prepared by melt mixing together (A) 100 parts by weight of an optically isotropic pitch having a softening point of 230.degree.-300.degree. C. obtained by heat treatment of a pitch while blowing an oxygen containing gas into the pitch, and (B) 10-50 parts by weight of an optically isotropic pitch having a softening point of 200.degree.-270.degree. C. obtained by polymerization of naphthalene in the presence of a Lewis acid catalyst. The optically isotropic pitch (B) is further characterized as having the property of being converted into an optically anisotropic pitch by the stress occurring at the time of spinning. The carbon fibers produced by spinning the spinning pitch into fibers have a double layer structure, the surface layer exhibiting optical isotropy and the center portion exhibiting optical anisotropy. The spun fibers are infusibilized, followed by carbonization and/or graphitization.

    摘要： There is disclosed a process for continuously producing a pitch-based carbon fiber felt which comprises the steps of spinning a pitch by melt blow spinning system; accumulating the spun fibers as a pitch fiber web composed of the aggregate of short fibers; continuously cross lapping the web; subsequently stabilizing the cross lapped web; carbonizing and/or activating the stabilized web; and then felting the resultant web. The above-mentioned process is capable of efficiently producing a pitch-based carbon fiber felt having uniform unit weight and excellent physical properties and well suited for use in high-performance thermal insulator, cushioning thermal insulator, filter media and adsorbent for water purification and solvent recovery, etc.
