製造 プロセス for carbon fiber square tubes consists of roughly 5 steps:
金型 製作
According to the the customer's requirements of the square tube size of the mold design, including the molding of the tooling requirements, but also take into account a series of conditions of the carbon fiber square tubes size, according to the need to determine the thickness of the the reserved tolerance tube.
In order to ensure dimensional accuracy, but also pay attention to the bending deformation, if the pipe size is larger, you need to use high-strength steel mold.
プリプレグ 切断
After the mold is designed, the carbon fiber prepreg needs to be cut according to the the size, the unidirectional carbon fiber prepreg needs to be stacked at 0 degree and 90 degree, and the way of laying needs to be determined according to the the stress situation of the carbon fiber products.
成形 of ブランク
After プリプレグ and mold are completed, the prepreg should be filled.
スプレッド カーボン 繊維 プリプレグ 層 層 上 金型, コンパクト プリプレグ to ensure that the resin flows inside after closing the mold.
The tighter the carbon fiber product is inside, the better the finished product will perform.
When installing the mold, it is also necessary to apply a release agent to facilitate the release of the mold.
加熱 硬化
後 金型 is completed, the carbon fiber billet is placed on the heat press to complete the curing of the carbon fiber square tube under temperature and pressure.
During the manufacturing process, it is necessary to pay attention to the changes of molding temperature and time parameters.
The manufacturing of carbon fiber square tubes is closely related to temperature, pressure and time.
後 成形 is completed, pressure and insulation are also maintained。
