Research on the heat distribution of benzoxazine resin carbon fiber wall panel
In order to solve the problems such as the difficulty of heat distribution test and identification of advanced benzooxazine resin panel and the poor quality of parts after forming,a matrix based segmentation and point selection of parts and fixtures were carried out for physical temperature field testing.During the hot pressing process,21 thermocouple monitoring points were used as testing conditions to study the rising and cooling rate,curing temperature and holding time,and to verify the temperature field variation and trend of benzoxazine carbon fiber panel during autoclave forming.The results indicate that the structure and material characteristics of the benzoxazine negative mold wall panel have a greater impact on the temperature field during hot pressing molding than the thickness size.The leading thermocouple is located at the forefront and outermost points on both sides of the windward side of the component,not the thinnest area of the component.The position of the lagging thermocouple is at the last end of the leeward area part,and it is not the thickest area of the part.
