Composite Autoclave Manufacturer Autoclave For Carbon Fiber Bicycle Frames
In the field of precision manufacturing of carbon fiber bicycle frames, carbon fiber autoclaves have become the key support for the industry's technological upgrades with their irreplaceable process advantages. This equipment allows carbon fiber prepregs to be perfectly formed in harsh environments through the synergy of precisely controllable temperature and pressure fields.
1. In terms of temperature, the temperature in the autoclave usually needs to be raised to 120-200ºC, which ensures that the resin matrix in the carbon fiber prepreg achieves optimal fluidity and reactivity. Taking epoxy resin-based prepreg as an example, in the heating stage of 120-140ºC, the resin begins to soften and flow, fully infiltrating the carbon fiber fabric; entering the curing stage of 160-200ºC, the resin molecules undergo cross-linking reactions to form a stable three-dimensional network structure. There are also strict requirements for the heating rate, which is generally controlled at 1-3ºC/min to avoid thermal stress inside the material due to rapid temperature changes.
2. Pressure control is also critical, and the working pressure range is usually 0.5-1.5MPa. At the beginning of the autoclave pressurization, the pressure of 0.5-0.8MPa squeezes out the air and excess resin between the prepreg layers to eliminate bubbles; as the temperature rises and the resin viscosity decreases, the pressure gradually increases to 1.0-1.5MPa to ensure that the resin fully penetrates the fiber layer and the layers of material fit tightly. The holding time depends on the material system and the thickness of the product, generally 1-3 hours, to ensure that the resin is completely cured and a dense composite material structure is formed.
3. The intelligent control system presets multiple sections of temperature rise/fall curves and pressure change curves through the PLC program. For example, the temperature rises slowly according to the set slope during the heating stage. After reaching the curing temperature, the temperature and pressure are kept constant for a period of time, and then the temperature is reduced at a rate of 1-2ºC/min. The pressure can be released and the can can be opened only when the temperature drops below 60ºC. Combined with the real-time feedback of the pressure sensor and the temperature sensor, the system can control the process error within the range of ±2ºC and ±0.05MPa, ensuring that the yield rate of mass production is stable at more than 98%.
4. Compared with the traditional molding process, the process compatibility of the autoclave technology is more groundbreaking: it can adapt to a variety of matrix materials such as epoxy resin and cyanate ester, and flexibly implement the "gradient curing" process to meet the molding requirements of structures with different curvatures (such as complex parts such as frame risers and front forks). This precise temperature and pressure control not only allows the carbon fiber bicycle bracket to have impact strength comparable to metal (tensile strength can reach more than 1500MPa) and extremely lightweight characteristics (density is only 1.6 - 2.0g/cm³), but also increases its riding rigidity by 30%, and reduces the overall weight to less than 50% of the aluminum alloy bracket, becoming the core competitiveness of competitive bicycles and high-end customized models.

Q: What are the advantages of autoclave molding compared with other composite molding processes?
A: Compared with hand lay-up molding, injection molding and other processes, autoclave molding has good temperature and pressure uniformity. Hand lay-up molding and other processes are greatly affected by human factors and environmental factors, and it is difficult to ensure the consistency of product quality. Autoclave molding can accurately control parameters such as temperature, pressure and time, and can produce large and complex structural parts with high quality and high performance. Moreover, the product has low porosity and good mechanical properties, which has obvious advantages in fields with extremely high quality requirements such as aerospace.
Q: To what extent can the temperature and pressure in the autoclave be accurately controlled?
A: The temperature control accuracy can generally reach ±2 - 3ºC, and the pressure control accuracy can reach ±0.01 - 0.02MPa. The specific accuracy will vary depending on the model, configuration and manufacturer of the autoclave. Such accuracy can meet the curing process requirements of most carbon fiber composite materials and ensure the stability of product quality.
Q: What is the material of the autoclave body? How to ensure the safety of the body?
A: The autoclave body is usually made of high-quality alloy steel materials, such as Q345R. These materials have good strength and high temperature resistance. In order to ensure the safety of the autoclave body, the autoclave body will undergo strict quality inspection during the manufacturing process, including non-destructive testing (such as ultrasonic testing, radiographic testing, etc.) to check whether there are defects inside the autoclave body. At the same time, the autoclave is also equipped with safety accessories, such as safety valves, pressure gauges, etc., and these safety accessories will be calibrated regularly to ensure that the pressure can be released in time under abnormal conditions such as overpressure to ensure the safety of equipment and personnel.
Q: What is the approximate service life of the autoclave?
A: The service life of the autoclave is related to many factors, such as frequency of use, working pressure and temperature range, maintenance, etc. Under normal use and good maintenance conditions, it can generally be used for 15 years. If the use environment is relatively harsh or the maintenance is improper, the service life may be shortened.
Q: How to ensure the uniformity of the temperature field and pressure field in the autoclave?
A: The autoclave is internally designed through a specially designed heating system (such as a hot air circulation system) and a gas distribution system to ensure uniformity. The heating system will cause hot air to circulate in the autoclave, so that the temperature is evenly distributed. The gas distribution system can ensure that the pressure acts evenly on the surface of the product during the pressurization process. In addition, during the equipment installation and commissioning stage, professional testing instruments will be used to calibrate and optimize the temperature field and pressure field.
Whether the wall thickness of the autoclave meets the requirements, etc.
