AI Technical Summary

Technical Problem

Existing methods fail to effectively monitor the quality of matrix materials during the infusion process in fiber-reinforced composite manufacturing, leading to potential defects in the final product and increased process times due to unchecked changes in resin quality.

Method used

A method and device that utilize a light source to illuminate the matrix material, detecting the light beam's path through the material with a sensor to determine deviations from a predetermined target path, allowing real-time monitoring of material quality without contact, and adjusting or terminating the infusion process based on quality parameters.

Benefits of technology

Enables quick, non-destructive assessment of matrix material quality, preventing defects and optimizing the infusion process, thereby ensuring high-quality fiber-reinforced composite components.

Abstract

Method for determining the material quality of a matrix material (3) which is part of a fiber composite material for the production of a fiber composite component, characterized by the steps: - illuminating the matrix material (3) by means of a light source (23) and detecting the light beam (26, 26a) of the light source (23) passing through the matrix material (3) by means of a sensor (22), - determining a deviation of an actual beam path of the passed light beam (26, 26a) of the light source (23) from a predetermined target beam path and - determining the material quality of the matrix material (3) as a function of the detected deviation by means of an evaluation unit (25).
