MORPHOLOGY OF PORES IN CARBON FIBER REINFORCED PLASTICS

The morphology of pores in carbon fiber reinforced plastics(CFRP) was statistically studied using microscopy and image analysis. The results show that pores tend to occur at the interfaces between the adjacent laminae and elongate along the interfaces. Both the area and the length of the pores increase if the pores content rises. It is also observed that the aspect ratios (width to length of a pore) of pores tend to be larger when the pores content decreases, and the pores are rounder and distribute more sporadically.
