Lightweight, high strength and good toughness are the most amazing and excellent properties of carbon fiber composites, and they are also the most utilized properties by people. However, are there any weaknesses that carbon fiber composites are afraid of?
When the sharp end of the axe hits the carbon fiber composite board, the solid carbon fiber composite board is pierced and broken by the sharp end of the axe. Why did the carbon fiber composite board, which has always been considered very strong, suddenly become vulnerable?

This is because when the solid carbon fiber composite board encounters 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. When the carbon fiber composite board encounters the puncture of 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 solid carbon fiber composite board to be pierced.
Therefore, carbon fiber composites are most afraid of puncture by sharp objects. It has a good performance in resisting the impact of blunt objects, but its ability to resist puncture by sharp objects is very poor.
Therefore, in our daily life, we should understand the characteristics of carbon fiber composite materials that are tensile-resistant but not puncture-resistant, and avoid letting carbon fiber products touch sharp pebbles or sharp objects to prevent rupture.
