Structure-Property Correlation of Composites Impregnated with Aspartimide Oligomer

Abstract:

Carbon fiber and glass fiber composites impregnated with aspartimide oligomer were fabricated and their structure-property correlation was studied. Experimental results reveal that with increasing chain length of aspartimide oligomer, mechanical properties of composites increase, but thermal properties decrease. With decreasing chain length, storage modulus and loss tan delta peak temperature of composite increase as a consequence of increased rigidity of matrix polymer resin resulted from crosslink density increase, concurrently, loss modulus and tan delta value of composites undergo a decrease.
