Dry carbon Volvo Vida Dice fiber production process

We modified the frequent use of the carbon fiber parts Volvo Vida Dice wet carbon fiber and dry carbon fiber, if not always contact with the wet and dry carbon fiber, it is difficult to distinguish whether the front of the carbon fiber article is dry or wet, but as long as the look will be able to find out the dry carbon fiber has a very different texture, dry carbon fiber absolute advantage is that the light quality dry carbon fiber may be 50% lighter than the average wet carbon fiber. What is the difference between wet and dry carbon fiber so it? Is the material issue?
Dry carbon fiber production process:
, The first ready to do motif, the impurity of the first mold surface cleaning, dust and other impurities will cause the shape of the carbon fiber defects, and therefore prepared the first step is the motif thorough cleanup. Paste carbon fiber cloth plastic coated with a release agent must first motif, to facilitate the release after the molding of carbon fiber cloth. Note smear must be uniform. The next will have to be on the dry carbon fiber cloth cutting, dry carbon fiber cloth motif cut this process must be very careful, then must be exactly right. Incidentally, when the carbon fiber cloth is removed from the freezers for the work environment at room temperature, humidity and air cleanliness have a very close relationship. Then you want to dry the surface of the carbon fiber cloth paste motif must be very careful when posted, and must be completely out of air between the motif and dry carbon Volvo dice vida 2011A  fiber cloth does not affect the hardness and appearance of the finished product in the paste motif when select Paste angle and direction must also be carefully considered.
Second, after the carbon fiber cloth paste is completed, they make wrapped step. Wrapped in one area is divided into three steps, from the film, breathable cotton, vacuum bag three packaging are indispensable. First, the surface of the carbon fiber cloth paste with release film, and then pasted in the surrounding layer of fixing a protective film. Will be posted on good protective film motif into the vacuum bag with breathable cotton, and then sealed. After vacuum extraction step of the sealing is completed. A vacuum process needs to be very stringent vacuum conditions will directly affect the molding effect.
After the vacuum bag sealed vacuum pumping test to ensure that the pressure in the vacuum bag inside between -0.09 to 0.01Mpa. Note To test the air leakage state, pause Pneumatic pumps in the extraction process, to  Autocom CDP Pro see whether the pressure inside the vacuum bag changes, movements of the vacuum bag to make changes or patches, whether the continue pumping pressure.
Third, the preparatory work is completed, and the hardening operation can now be performed. Low when the resin is in semi-hardened state, with the temperature rise of the resin will gradually liquefied, the resin will harden and when the temperature exceeds a certain level. To this end, it is necessary in the high pressure furnace is pressurized and heated, by adjusting the ratio between the temperature and the time of the high pressure furnace in order to burn out a high quality of the finished product would be a key ring. When the products into the high-pressure furnace, the time and temperature of the operation in the automatic control on the front panel of the high-pressure furnace, maintaining the temperature at a number of degrees, the number of degrees per minute warming complex parameters must be accurately set, in addition, dry carbon fabric  Autocom Cdp Pro 2012 the number of layers used for the effects of temperature and time also exist. Heating cycle of time called "Cure Schedule", the control of the heating time is confidential level of long-term continuous carbon fiber production plant research.
