What are the causes of defects in carbon fiber tubes?

In addition to the strength superior to steel and the weight reduction effect of a large proportion, the surface quality and manufacturing precision of carbon fiber pipes are also important factors affecting their application effects. Carbon fiber tubes are widely used in our production and life, but there are also defects in carbon fiber tubes. What are the reasons for the defects?

The surface defects of the finished carbon fiber pipe fittings mainly include wrinkles, streaks and rich glue. The occurrence of these problems is mainly concentrated in the prepreg layer. When using the carbon fiber composite prepreg layer, if it cannot be applied Sufficient tension to compress the prepreg laminate will make the layers of the composite prepreg laid relatively loose, and the overall thickness will exceed the thickness of the target pipe product.
