Reinforcement of concrete used in construction of new materials, composite materials

Gluten is the pitch of continuous carbon fiber or polypropylene continuous carbon fiber epoxy fastening a variety of grid reinforcement. Structure of water and the water wheel with oak ribs and poor enhancement of environment (corrosive) parts of the clam bar children has increased more than Duo. Water extraction is also used as an argument zk. tt threshold plate. Storage of chlorine and water purification field wall panels enhanced the interval reinforcement. Department of ships and other floating bridge with concrete before the bar is also enhanced with a new reinforced material (Figure 8 omitted). In the effective use of high tensile strength characteristics of high strength carbon fiber, the reported primarily as a civil structure of materials to tensile stress practical cases. July 1986 opening of the West German city of Duesseldorf Wolf, 乌尔登柏尔 Kusiduole road bridge 47 meters long. 15 meters wide, prestressed concrete bridge. Is the first high-performance composite materials using glass fiber as a tensile strength of the material subjects. Japan's utility'd completed in 1988 a new stone base material III J11-rich county to the county town yesterday to the Luk Keng (mainly Lot Road, Bang valley one line) pre-pull pure pyrolytic carbon fiber (pc) concrete slab bridge. Its length is 6.1 meters, the boom length of 6.06 meters. Tensile strength of carbon fiber material used tow CFRP. Salt bridge in a corrosive environment, the old reinforced concrete slab bridge was badly damaged because of salt corrosion, as appropriate countermeasures, in the PC concrete was first used CFRP. Bridge because the tensile strength of carbon fiber materials used in the PC, and thus become the world's first bridge, from the attention (Figure 9 omitted) in the reinforced concrete pillars and thin and high chimneys and other enhanced seismic construction, use of carbon fiber for the excellent performance of structural materials. Its implementation is wrapped in the original structure of the method of carbon fiber. Apply to the original figure of reinforced concrete examples of smoke are: height of 34 meters, diameter I. 76-3.02 meters and height of 45 meters, diameter I. 10-2.30 meters and other chimney. Application for Buxiu have removed ladders, lightning, etc., the base of the concrete surface for processing, adjusting, full posts posted in the axial chimney 30 cm wide. L0 a l5-meter long strip of resin carbon fiber, with automatic winding machine winding along the circumferential direction of the chimney of continuous carbon fiber (Figure 1o omitted). The concrete surface is covered with CFRP, rain,[link widoczny dla zalogowanych], and harmful gases would be difficult to invade, with the advantages of preventing deterioration. Above, the carbon fiber as the center of the building, civil engineering reinforced concrete structures strengthen the status of the development of composite materials was described. Due to space relations, there are many ways not fully explained, please understand.

ProcIntConfComposMater8th, 1992,3,22 C/1--22C/1l (in English) can be obtained using the immersion technique cF enhanced two-dimensional PAN-based asphalt c / c composite material. Under certain conditions will be fine fiber fabric with powder mixture of asphalt, and determined the process of stabilization and carbonization process parameters. Stabilization process is the key. Stabilization process of the material was reasonable to prevent carbonation occurs when the matrix expansion. Optimum temperature for the oxidation of 200 ℃. Aurora Spectroscopy and Scanning Auger spectroscopy results show that the matrix is more difficult than the fibers undergo oxidation. 118; 44 ~ 55d pitch-based carbon fiber manufacturing process,[link widoczny dla zalogowanych], application of the centrifugal molecular distillation unit kumazawaYukio listless, etc. (Japan), P92, 249,95 l (4 pages) in order to obtain a stable, CF used in the manufacture of asphalt, the device can be provide a means of vacuum gas recovery of raw materials (such as oil distillation residue) for centrifugal molecular distillation 118; 44 ~ 58g pit with thousands of Ba Tuo's wear made of glass bud of the fixture TakeharaMasaharu resistance, etc. [at) JP92, 280,867 (4 pages) is made of carbon fiber prepreg impregnated with asphalt, cutting to the appropriate size,[link widoczny dla zalogowanych], hot pressing, and finally to carbon and graphite.
