| Outline of Annual Research Achievements |
Based on the peridynamic (PD) theory, a new numerical method which employs heterogeneous particle model was proposed for the mechanical analysis of UT-CTT. The tensile properties of UT-CTT were investigated through this numerical method.The random orientation distribution of carbon fiber are represented through the random orientation distribution of bond between reinforcement particles, which is realized through randomly selecting particles as the reinforcement component.
This heterogeneous particle model provides a new numerical modeling method for the heterogeneous materials with random orientated reinforcement phase. The application of this heterogeneous particle model is not limited to the UT-CTT. The numerical analysis on other random orientated DCFRTP, such as carbon-fiber paper reinforced thermoplastics (CPT), carbon fiber mats reinforced thermoplastics (CMT) , and sandwich structure with CPT and CTT, will be conducted using this PD model in the next year.
