Development of a Spreading Module for the Control of the Spreading of High Modulus Fiber Tows
High modulus fiber tows are spread for the production of many semi-finished textiles for the production of fiber reinforced plastics. However, the spreading width and the quality of the spread tow are varying during the production. The quality of the spread tow is defined by the consistency of the spreading width as well as by the amount of fiber breakage. In order to control the quality of the spread tow an active spreading control module was designed. The module controls the rotational speed of the spreading bars, the pretention of the tow and the wrapping angles of the tow around spreading bars. Furthermore, the interactions between the controllable process parameters and the spreading quality were determined by regression models.
