The curve of carbon fiber yarn oven (also called composite autoclave) matrix resin mainly influence by resin molecular structure, also influenced by other components such as curing agent, cross-linking accelerator and so on. Outside conditions such as temperature, pressure and time are very important to curving process, these three datas called process parameters.
Now the current domestic and foreign carbon fiber yarn oven resin curing pressure, except for polyimides, is generally controlled within the range of 0.3-0.6Mpa. Composite materials pressure for carbon fiber yarn oven is usually lower than 1.6Mpa. For technical process, the transformation of matrix resin from linear structure to three-dimensional network structure can be divided into three stages such as flow stage, gel stage and curing stage, this process is among stable temperature. Domestic aircraft structure used composite matrix resin curing temperature. This temperature is the upper of domestic carbon fiber yarn oven temperature.
Distribution of temperature in composite autoclave will have air stirring circulation device in it, the main function makes the temperature uniform.
The main composite materials production defects from high to low is stratification, porosity, rich fat, poor adhesive, debonding, looseness, weak adhesive and deformation, among this stratification take high, the proportion of excess over pores and pores is also relatively high, while the proportion of other defects is relatively low. So stratification defects are composite autoclave technical process. When the material system is consistent, the delamination is mainly affected by the structural form and technological conditions of composite components.
