Polymer matrices for carbon fiber-reinforced polymer composites [PDF]

open access: yesCarbon letters, 2013
Carbon fibers (CFs) have high service temperature, strength, and stiffness, and low weight. They are widely used as reinforcing materials in advanced polymer composites. The role of the polymer matrix in the composites is to provide bulk to the composite laminate and transfer load between the fibers.
