What is typical fiber breakage during molding and how does it affect properties?

Even with the utmost care, some fiber breakage will occur during the molding process – this is to be expected. Successful molding practices minimize broken fibers and result in a normal bell-curve distribution of complete long and broken fibers.

If excessive fiber breakage occurs molded articles will not have the high stiffness and toughness associated with well made long fiber composite parts. Consult our Long Fiber Molding Guide for details on maintaining optimum physical properties during molding.
