通过研究自动铺带设定温度对预浸料粘性的影响以及自动铺带橡胶辊压力和带间间隙对层压板性能的影响,讨论了T700/3234单向环氧预浸料自动铺带工艺特性,确定了T700/3234的自动铺带工艺参数,满足了大型复合材料壁板类产品的制造要求.
The Automatic Tape Layup (ATL) technique is extensively applied on laying up the unidirectional prepreg for the large-scale composite panels of an aircraft, instead of artificial.In this paper, by studying on how the heating temperature has influence on the prepreg tack and how pressure from the rubber roll and gap between two tapes have influence on the lamination performance when using ATL, the automatic tape layup technology for an unidirectional tape prepreg, T700/3234 is discussed, and the appropriate processing parameters are determined when T700/3234 is used for ATL, such as the heating temperature should be set as 50 ℃, the pressure from the rubber should be 7 Bar and the gap between two tapes should be set as 1 mm.A large-scale wing panel from T700/3234 composite has been successfully manufactured by the ATL parameters for a fighter.
