SYSTEM AND METHOD FOR FIBER ARRANGEMENT INSPECTION IN PRODUCING FIBER-REINFORCED-COMPOSITE-MATERIAL ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a system and a method for inspecting an uncured fiber-reinforced-composite-material element by performing noncontact 3D measurement of an element using a 3D digital image correlation with patterned illumination.SOLUTION: A system comprises: a projector 12 that is configured to project a light pattern on a structure 30; and digital cameras 14 and 14' that are configured to capture the light pattern, and may comprise an automatic fiber arranging device 40 that is configured to lay uncured composite material on the structure. A method comprises: projecting a light pattern on a structure; obtaining a reference 3D profile of the structure by capturing the light pattern on the structure; laying uncured fiber pieces on the structure; projecting the light pattern on the uncured fiber pieces; obtaining a test 3D profile of the fiber pieces by capturing the light pattern on the uncured fiber pieces; and calculating a thickness difference between the test 3D profile and the reference 3D profile.SELECTED DRAWING: Figure 1
