Description du projet/ Project Description
This project investigates the defect formation emerging during the AFP manufacturing of curvilinear shaped composite structures. An integrated optimization module will be developed to manufacture optimized composite parts free of detrimental defects.
Objectifs/ Objectives
1) Establish experimental correlations and semi-empirical rules between the manufacturing defects, i.e., gaps, overlaps, angle of orientation and fiber waviness, and the mechanical properties of simple and complex shaped composite structures. Through defect simulation, testing and analysis, a database of admissible AFP flaw tolerances will be determined for prescribed structural geometries that may include impacted panels, holes, bevels, ramp-ups, angles, under static and fatigue loading.
2) Develop a closed loop simulation system that links existing software packages and computational process tools with the purpose of 
a) predicting size, shape and location of the process defects, and analyzing their impact on the mechanical properties, 
b) integrating a multi-objective optimization tool that can tailor 3D optimized tow paths for a set of user-defined manufacturing criteria and structural geometries.
