摘要：

Modified Halpin-Tsai equations to fit experimental data on the mechanical characteristics, such as modulus and fracture toughness of random orientation nanotubes-polymer composites at high volume fractions of the CNT fillers are discussed. Through extensive literature survey, we postulate a semi-empirical parameter p, related to the degree of CNT aggregation with increasing the volume content. Such analyses have been used to predict the value of modulus and fracture toughness of CNTs/polymer composites. Experimental data and predict value of modulus and fracture toughness of CNTs/polymer composites from literature listed in this paper. Results show that the modified Halpin-Tsai equations can not only predict the modulus but also fracture toughness of CNTs/polymer composites when the matrix is brittle and the differences between the experimental data from different publications and the predicted value are mostly around +/- 5% and +/- 10% respectively for modulus and fracture toughness of CNTs/polymer composites.
