Abstract
The target of this research is to enhance the production efficiency of composite sandwich automobile structure. The most common used structure, body in white, is adopted and modified by this research to revise the design process by the manufacturability and exerted force type to replace the traditional monoque structure, which acquires a series of cumbersome and labor intensive manufacture process.
In the beginning, the limit of automatic forming process of carbon sandwich composites has been investigated. Followed by the simulations about the static stiffness and strength of the car structure, and obtain the direction of capital stress in the structure to judge whether the continuity of the fabric is needed in each part of the structure to avoid stress concentration and failure in places where fabric has to be continuous.
In the research, a "Judging Jointing Strength Process" is proposed and using ABAQUS Cohesive Element, simplify traditional complex model that is applied to predict jointing type load capacity. Moreover, this process is verified by comparing the result with two T-joint failure mode and applied different joint-type design. Final, joint type affect load capacity applied into a simplified vehicle model, whether confirmed preliminary design reach the requirements.
