What problem can occur from using dull chopper blades?

Using dull chopper blades can lead to the issue of spring back in composite manufacturing processes. When blades are not sharp, they do not effectively cut through materials, which can result in jagged or uneven edges. This incomplete cutting action can cause the material to behave unpredictably during the curing process, creating tension and ultimately leading to a phenomenon known as spring back.

Spring back occurs when the fibers or layers of the composite try to return to their original position after being deformed or cut. A precise, clean cut is crucial to maintain control over the material’s desired shape and properties. Therefore, the use of sharp blades is essential for achieving accurate cuts and ensuring that the composite maintains its integrity throughout the manufacturing process.

While other options may relate to different issues in the composite processing, the specific consequence of dull blades manifesting as spring back is critical to understand for maintaining the quality of composite structures.
