When the sharp end of the ax hit the carbon fiber composite material plate, the strong carbon fiber composite material plate was punctured and broken by the sharp end of the axe. Why did carbon fiber composite panels, which have always been considered strong, suddenly become vulnerable?
This is because when the strong carbon fiber composite material plate meets the impact force of the surface, the carbon fiber filaments woven vertically and horizontally inside it can evenly disperse the force and will not cause rupture. However, when the carbon fiber composite material plate is punctured by a sharp object, the huge impact force is concentrated on one point, and the sharp puncture point can easily penetrate the gap between the carbon fiber filaments woven vertically and horizontally inside it, causing the strong carbon fiber composite material plate to be punctured. pierce.
Therefore, carbon fiber composite materials are most afraid of puncture by sharp objects. Its impact resistance against blunt objects is quite good, but its ability to resist puncture by sharp objects is very poor.
Therefore, in our daily life, we need to understand the properties of carbon fiber composite materials that are tensile and not puncture resistant, and avoid letting carbon fiber products touch sharp pebbles or sharp objects to prevent rupture.
