When using a pneumatic scraper, what trajectory should be used to prevent damage to the composite structure?

The correct trajectory to use when operating a pneumatic scraper on composite structures is a low angle. This approach is important because a low angle minimizes the risk of damaging the composite materials during the scraping process. Composite structures are often sensitive and can be easily compromised by excessive force or improper scraping techniques. Using a low angle allows the scraper to glide over the surface rather than digging into it, which helps maintain the integrity of the composite layer beneath and minimizes the potential for delamination or other structural damage.

Other angles, such as a high angle or vertical straight, may apply too much force to focus on a small area and can increase the risk of gouging or tearing the composite material. A random angle is not recommended as it lacks precision and control, further increasing the risk of damaging the structure.
