[0051] Example 1
[0052] Intermediate frequency electromagnetic induction heating curing temperature 300℃~320℃ carbon fiber polyimide panel, the details are as follows:
[0053] The pre-cured composite material is made of carbon fiber / polyimide board, with a length of 400mm, a width of 260mm, and a thickness of 2mm.
[0054] The mold is made of steel plate, one on the upper and lower sides, length 420mm, width 300mm, thickness 12mm.
[0055] The breathable and thermal insulation layer adopts a two-layer structure. The inner material can withstand high temperatures exceeding 320℃. The upper and lower planes of the forming mold 2 are made of heat-insulating rock wool boards with a thickness of 5mm. The narrow parts around the mold are made of glass fiber mat. The actual thickness is not less than 5mm to ensure that the steel mold is not exposed. The outer layer material is made of ordinary polyester non-woven breathable felt, which is heat resistant to 200 ℃, and the compacted thickne...
