Abstract
In this study, the fabrication of laminated composite grids, as a new class of grid structures, is presented. These structures can be constituted from a various number of grid layers, with different patterns, fibers and orientations. This concept yields to a large variety of laminated grid configurations with different coupling effects compare to conventional grids. In the current study, the fabrication of a laminated grid plate, which composed of four orthogrid layers, is presented. The vacuum infusion process (VIP) is employed to manufacture the specimen. Moreover, a simulation is conducted using COMSOL Multiphysics software to determine the appropriate locations of resin inlet and air vent tubes. The degrees of cure and temperature profiles of the specimen are obtained in simulation and experimental studies. The results show, the simulation fits the experimental observations reasonably well and the VIP method is confirmed to be appropriate for manufacturing the high-quality laminated grid.
