At present, the telescopic fish rafts sold in the domestic fishing tackle market are mainly classified into glass fiber bream and carbon fiber bream (hereinafter referred to as glass fiber reinforced plastic and carbon fiber reinforced plastic). The carbon fiber enamel has the advantages of lightweight, small sag, high strength, wear resistance and corrosion resistance, and is more popular among the anglers. Here are some ways to identify true and false carbon fiber.

     Carbon fiber is a very fine carbonized fiber made of polyacrylonitrile fiber (PAN) or carbonized by bitumen and has a diameter of about 10 microns. 78 pieces are arranged together to have thick hair. Carbon fiber has the characteristics of high strength, high-temperature resistance, corrosion resistance, friction resistance, and good electrical conductivity. Because the carbon fiber is too thin, it can not be woven into a fabric like glass fiber, and only the longitudinal alignment is fixed on the lining with a glue. Therefore, the true carbon fiber cloth has only the warp without the weft, which is important for distinguishing between carbon fiber and fiberglass. Sign. Sometimes a mesh pattern can be seen on the carcass of the carbon fiber, which is the offset of the lining through the resin, which is quite different from the obvious vertical and horizontal interlacing of the fiberglass cloth.

    The carbon fiber crucible is manufactured in the same way as the glass fiber crucible. The dip cloth is cut into a narrow, narrow trapezoidal roll on a conical steel core, and then spiraled from the head to the end with a transparent glass ribbon. The glue is dried in an electric furnace, and then taken out from the furnace to withdraw the cross core, and the glass ribbon on the carcass is removed, and after being trimmed, polished, lacquered, and assembled, the fish is formed. Since the cloth that has just been immersed in rubber is soft and the glass ribbon is tightly wound, the corpus callosum is shaped into a rugged spiral instead of a carbon fiber cloth or a fiberglass cloth spirally wound. Therefore, it is better to choose a thread when you buy it.

    At present, the carbon fiber in the domestic fishing gear market is divided into two types: full carbon and half carbon. Since carbon fiber is expensive, it is necessary to make the diameter of the crucible as fine as possible to reduce the amount of carbon fiber cloth. The diameter is small and the weight is light. The outer diameter of a 7-meter 7-meter-long all-carbon handcuff is only equivalent to the outer diameter of the glass fiber 竿 5 knots and 5 meters, which is well recognized from the outside.

   There are two kinds of semi-carbon bismuth: one is to attach the carbon fiber cloth to the outside of the fiberglass cloth and roll it on the core. After the boring is done, the inside of the fiberglass cloth is carbon fiber cloth, and the back cover can obviously see the tube. The inside of the wall has a mesh pattern, the texture is rough, and the color is dark. There is no pattern on the outside of the pipe wall, the texture is fine, and the color is silver gray. Such tendons are usually thicker in the body, and the pockets are the same as ordinary fiberglass, with a contraction length of about 58 cm. The other is to make the most fragile first few sections made of all-carbon cloth, and the last few sections are made of fiberglass cloth. This kind of crucible not only has the advantages of carbon fiber crucible but also reduces the production cost and price. The love of fishing friends.

   There are two ways to distinguish between carbon fiber and fiberglass: one is to look at it. Open the back cover of the carcass. If it is carbon fiber, you can see that the unpainted part of the carcass is silver-gray, the same color as the carbon brush on the motor, and the texture is fine and without weft. The fiberglass cloth dyed with carbon black powder is darker in color, has a distinct weft, and has a rough body. The second is measurement. Put the multimeter to the K-file, the resistance file, and put the two test rafts on the unpainted body at the same time. If it is carbon fiber, the hands will swing to the right, otherwise, it will not move.
