Effect of Novolac Resin and Modified Novolac Resin on Mechanical Properties of Carbon Fiber/Epoxy Composites

open access: yesAdvances in Polymer Technology, 2014
ABSTRACTThe effects of novolac resin (NR) and modified novolac resin (MNR) on the stiffness and toughness of the carbon fiber (CF)/epoxy composites were studied when using these two kinds of modifiers with different physical and chemical performance. The results show that both NR and MNR are excellent toughening agents for the CF/epoxy composites, and ...
