1. Why do composite fiber material repairs use a laser displacement sensor?

The laser displacement sensor has a large range, and reinforced composite fiber materials are increasingly used in the aviation and automotive industries. The robustness and light weight characteristics of such materials are particularly suitable for the above industries. When the fiber is damaged, it needs to overcome special difficulties to repair it, and the damaged part must be peeled off layer by layer to achieve thin layer reconstruction. The difficulty of this job is to avoid cutting fibers and delamination. At present, similar complex maintenance work is carried out manually, and the use of laser displacement sensors can realize automatic non-contact surface measurement to eliminate defects in a short time. In order to perform maintenance on aircraft many companies develop laser displacement sensors ‍mobile modules, which are actually five-axis machining cells.

2. How it helps to achieve composite fiber material repair

In order to identify component defects, laser displacement sensors and laser profilers obtain the geometry of the defect, since the device under test may be damaged at any location, the surface geometry needs to be measured before repairs. Laser displacement sensors must be capable of measuring a wide variety of surfaces, including painted surfaces, unpainted surfaces and weathered surfaces. In order to prevent secondary damage in the measurement, the measurement task uses a series of laser displacement sensors with a large range to measure away from the object to be measured. corresponding data for maintenance.

The wide-spot laser displacement sensor can cooperate with other sensing equipment to repair various complex fiber materials. After repairing, the composite fiber material is rarely damaged again, and in terms of service life, the service life of the fiber material is similar to that of other parts of the fiber material. It has also been improved year-on-year, and the use of this laser displacement sensor for rapid positioning has also solved the problem of composite material repair.
