Reinforcing fiber scrims and method for the production thereof

摘要

The invention relates to reinforcing fiber scrims, comprising multi-layer, multiaxial scrims, which each comprise individual fibers arranged next to each other in a layer, wherein at least two layers are at an angle to one each other in the layer plane and are connected by a fixing means. To improve the processing of the multiaxial scrims and significantly reduce the processing time, at least two prefabricated MD scrims are arranged at an angle in a layer plane and connected to each other. Thus a reinforcing fiber scrim is provided, which has at least two individual fiber scrims and which, for a 0° position of the individual MD scrims, has six individual fiber scrims. The number of MD scrims arranged one over the other can be arbitrarily increased so that an increased layer structure is already present when the reinforcing fiber scrim is produced.

主权项

1. Reinforcing fiber scrims (20), comprising multi-layer MD scrims (multiaxial scrims; 10, 11, 12), which each comprise individual fibers arranged next to one another in a layer, wherein at least two layers are at an angle vis-a-vis one another with respect to the longitudinal extension of the layer plane and are connected by a fixing means, characterized in that at least two prefabricated instances of multi-layer MD scrims (10, 11, 12) are arranged at an angle vis-a-vis one another with respect to the longitudinal extension of the multi-layer MD scrims and connected to one another, wherein the multi-layer MD scrims are wrapped together to form the reinforcing fiber scrims such that at least one of the prefabricated instances of multi-layer MD scrims covers one side of the reinforcing fiber scrims proximate to one longitudinal edge and covers the other side of the reinforcing fiber scrims that is proximate to the other longitudinal edge.
