Project Description
The project "Solid 3D Printed Swept Inserts for Composite Material Joints" aims to develop innovative joining techniques for composite materials using advanced additive manufacturing. The research will focus on designing, 3D printing, and testing specialized swept geometry inserts that provide improved stress distribution at joint interfaces compared to traditional fastening methods. Undergraduate researchers will systematically investigate various insert geometries, printing parameters, and material combinations to optimize structural performance while maintaining manufacturing feasibility. The methodology involves computational modeling to predict stress concentrations, followed by fabrication of prototype inserts using polymer and metal 3D printing technologies. These inserts will then undergo mechanical testing to evaluate load transfer, fatigue resistance, and failure modes when incorporated into composite joints. The project combines elements of materials science, mechanical engineering, and additive manufacturing to address a significant challenge in composite structures: creating strong, reliable joints without compromising the inherent advantages of composite materials. Success would yield valuable design guidelines for lightweight, high-performance structural connections applicable in aerospace, automotive, and renewable energy sectors where weight reduction and structural integrity are paramount.
Tasks and Responsibilites
Student researchers will be responsible for multiple aspects of this multidisciplinary investigation. Tasks include conducting literature reviews on composite joining techniques, creating CAD models of various insert geometries, operating 3D printers to fabricate test specimens, and performing mechanical testing using universal testing machines. Students will also collect and analyze experimental data, document findings in laboratory notebooks, develop analytical models to predict joint behavior, and prepare technical presentations and reports.
