We make motorcycles parts from carbon fibre!
The products are made from start to finish in our company, so we have control over the entire process and can guarantee the best quality. We make the molds for the products ourselves and test them on the motorcycle until they fit perfectly. Once the mold is perfect, it is ready to make the carbon parts.
The materials we use are pre-impregnated fiber – ‘prepreg’ carbon (PLAIN 200g/m2 or TWILL 245g/m2), aramid – kevlar and fiberglass in dry and pre-impregnated form. Special procedure in an autoclave where we place pre-impregnated carbon fiber on a tool, than place a release film and felt on it and fasten it with a special vacuum bag and sealing tape. The foil contains a valve, which is connected to a tube that sucks out air and compresses carbon layers. Products are then placed on a shelf in an autoclave, where they are strengthened up to 6 bars and 150°C.
Autoclave processing is the most common method used for curing thermoset prepregs. The curing of thermoset composites involves both mechanical and chemical processes. Mechanically, pressure is applied to remove trapped air and volatiles, and to consolidate the individual plies and fibers. Chemically, a crosslinking reaction must be initiated and taken to completion to form a rigid matrix. Crosslinking is most commonly initiated through the application of heat, though it also may be initiated by exposure to ultraviolet light, microwaves, or high-energy electrons (e-beam curing). In the autoclave process, high pressure and heat are applied to the part through the autoclave atmosphere, with a vacuum bag used to apply additional pressure and protect the laminate from the autoclave gases. The cure cycle for a specific application is usually determined empirically and, as a result, several cure cycles may be developed for a single material system, to account for differences in laminate thickness or to optimize particular properties in the cured part.
The typical autoclave cure cycle is a two-step process. First, vacuum and pressure are applied while the temperature is ramped up to an intermediate level and held there for a short period of time. The heat reduces the resin viscosity, allowing it to flow and making it easier for trapped air and volatiles to escape. The resin also begins wetting the fibers at this stage. In the second ramp up, the temperature is raised to the final cure temperature and held for a sufficient length of time to complete the cure reaction. During this step, the viscosity continues to drop, but preset temperature ramp rates and hold times then stabilize viscosity at a level that permits adequate consolidation and fiber wetting, while avoiding excessive flow and subsequent resin starvation. These control factors also slow the reaction rate, which prevents excessive heat generation from the exothermic polymerization process.
After the autoclave process, the products are manually sanded and polished and prepared for varnishing. We use ceramic lacquering for finishing products that gives permanent protection, UV protection, it is 100% chemically resistant, enables the coat to prevent water and dirt from getting in contact with the surface, very high hardness, resistance to blows, abrasion and scratches.
