Abstract
Fiber-reinforced materials are increasingly being used in serial production of automobiles, airplanes or wind rotor blades due to their outstanding mechanical abilities in combination with their advantageous lightweight character [1]. The growth in use of technical textiles as reinforcement material demands for production technologies which are able to supply reinforcement textiles in large volume with a constant high production quality. This paper introduces a novel production technology for non-crimp fabrics (NCF) which aims for a large-scale production. The knitting yarn which is commonly used for bonding the reinforcement layers in non-crimp fabrics [2] is substituted by local injected adhesive dots. This improvement in the production process enables the potential for better reinforcement qualities, due to the absence of fiber misalignment, yarn damages or "fish-eyes" evoked by the stitching needles. These defects can be seen as most disadvantageous in the classic warp knitting process because of resin enrichments after infiltration with a matrix system [3]. The methods and results for qualifying the chemical binders according to their function as matrix conform yarn to yarn binder are presented to ensure the use in a composite material. Additionally, a model for numerical drape simulation was developed which is able to account for the local fixation with adhesive dots. This local fixation enables a variable adjustment of the drapability due to the inhomogeneity of the layer bonding. The variable bonding of the reinforcement layers and the adjustable drapability can be represented with the developed mesoscopic model.
