It is related to the curing system. PREVIOUS TECHNIQUE 10 In the production of composite materials, resin-based materials are subjected to specific temperatures and pressures. Various pieces of equipment are used to enable curing under specific conditions. In particular... high-performance composites used in the defense, aerospace, and space industries Autoclave systems and composite curing ovens are widely preferred in production. 15 In autoclave systems, temperature and pressure are applied together, and composite materials are used. In curing ovens, a temperature-controlled process is primarily carried out. Curing During this process, the material must be heated to the target temperature according to a specific heating rate. It needs to be held at a specific temperature for a certain period of time and then cooled down in a controlled manner. Therefore, the temperature distribution inside the furnace, air circulation, heating and cooling ramps, 20 Traceability of vacuum level and process data ensures the mechanical and structural integrity of the produced composite part. It has a direct impact on its thermal properties. Existing autoclave systems have high investment and operating costs and are pressure vessels.

It can bring about a significant advantage of existing composite curing ovens that do not apply pressure. Some of them have limited operating temperatures and high glass transition temperatures. It cannot reach the temperature levels required by the special resins. At high temperatures 30 In existing ovens that are operational, maintaining temperature homogeneity throughout the oven volume is also necessary. Prevention of body deformations due to thermal expansion, insulation properties sustainability, precise management of heating and cooling ramps, and vacuum It is becoming difficult to reliably monitor their values. 35 Furthermore, some existing systems perform cooling using only ambient air or fans. This is achieved with assisted passive cooling, therefore by resin manufacturers. 2 Precise implementation of the defined cooling profiles is not always possible. This does not happen. Uncontrolled or non-homogeneous cooling can cause damage to the composite part. This leads to the formation of residual stresses, microcracks, and geometric deviations. Similarly, inadequate air circulation can affect the air quality of shelving and loading arrangements. hindering flow, limited temperature measurement points and insufficient accuracy of process data 5 inability to record, composite parts located in different regions differing from each other This can lead to curing issues and a decrease in the repeatability of production quality.

The mentioned internal volume is used for heating and holding composite materials at a certain temperature. and creates the process environment in which it is located during the cooling stages. Curing 30 The outer shell (10) of the oven (11) surrounds the inner volume and is between the inner volume and the outside environment. It defines a physical boundary. The outer casing (11) is resistant to the high temperatures generated in the inner volume during the curing process and repeated It is designed to withstand temperature changes. The inner surface of the outer shell (11) and 35 between its outer surfaces, one or more elements limit the heat transfer from the interior to the exterior environment. Multiple insulation layers may be present. The material of the insulation layers, thickness and placement according to the working temperature that the curing oven (10) will reach. It is determined that the inner surfaces exposed to high temperatures and the outer casing (11) are carriers. Different amounts of thermal expansion occur due to the temperature difference between the parts. This can occur. Therefore, the load-bearing elements that form the outer body (11), Coating elements and connection areas are designed taking these expansions into account. 5 It can be configured. Thus, during repeated heating and cooling cycles, the external There is a possibility of stress accumulation, cracking or permanent deformation occurring in the body (11). is being reduced.

This modular structure allows for the standard (10) of the curing oven. Transportation by road is facilitated. Body sections, assembly They are fixed together in place, and the joint between them allows 15% of the heat from the interior volume to escape. It is insulated in a way that restricts its passage. The curing oven (10) contains at least one door that provides access to the interior volume. The door is kept closed during the curing process, preventing the interior space from being separated from the outside environment. It limits the direct connection. Heat and gas between the door and the outer shell (11) 20 A sealing structure that reduces leakage may be found. In a possible structure... the door must have at least one door lock that prevents the door from opening when the curing process is started. It is connected to the mechanism. The door locking mechanism can be mechanical, electromechanical or It can operate pneumatically. The mechanism in question allows the internal volume temperature to be adjusted in advance. The door opens at 25°C before the value falls below a defined safe level or the process is terminated. This does not allow it to be opened. Thus, the curing oven (10) operates at a high temperature. Next, the door is prevented from being opened by the user. The curing oven (10) has at least one circulation fan to circulate the gas in the interior volume. (12) contains. The circulation fan (12) moves the gas in the interior volume and heats it. 30 It enables the transfer of energy to the surroundings of the composite materials.

In a possible configuration, the circulation fan (12) is located at the rear of the curing oven (10). It is located and directs the gas from the upper part of the internal volume to the lower part. Gas The flow direction depends on the dimensions of the interior volume, the arrangement of composite materials, and the 35 within the interior volume. It is determined according to the position of the carrier elements. Gas circulation speed during the heating phase. It can be increased, and during the holding phase at the target temperature, it will maintain the temperature distribution. 6 A different fan speed can be applied. During the cooling phase, the circulation fan (12) The continued operation involves circulating the gas within the internal volume between different regions. It makes it possible. The curing oven (10) contains at least one heating cassette (13) which provides heating of the interior space. 5 One or more heating elements that convert electrical energy into heat energy are located inside the heating cassette (13).

Each heating cassette (13) The electrical energy provided is individually adjusted and the heat is transferred to different areas of the interior space. The quantity can be changed. Numerous temperature sensors are installed in the curing oven (10) to measure the temperature inside the volume. (14) are located. Each of the temperature sensors (14) is located in relation to the temperature of the region in which it is located. It produces a corresponding temperature data, and this data is used to monitor the curing process. It is used in the design. In a possible configuration, at least temperature sensors (14) One of them is a thermocouple. The use of thermocouples allows measurements to be taken in a high temperature range. Temperature changes are detected quickly and the curing oven's high temperature 25 It allows for the acquisition of temperature data under working conditions. Temperature sensors (14) are distributed in the top, front, rear and side parts of the interior space, Thus, temperature can be measured not from a single point, but from different points within the interior volume. By comparing temperature data from different temperature sensors (14), the internal volume was determined to be 30 whether one region is warmer or colder than other regions It can be determined.

If it remains below the target value, the energy supplied to the heating cassette (13) can be increased. If the limit is exceeded, it can be reduced or cut off. The internal volume varies. If the temperature difference between the regions increases, the circulation fan (12) will operate 10 The situation can be changed. The processing unit is designed to apply curing profiles corresponding to different resin types. It can be configured.

At least some of the air is removed, creating a process environment with reduced oxygen content. 20 is formed. Thus, during the curing process carried out at high temperatures. from composite material, resin or other substances that may be present in the interior volume The risk of fire that may occur is reduced. Here, nitrogen is used as a non-combustible gas.
