This dissertation presents four unique contributions to additive manufacturing of carbon fiber composite lattice structures. The lattice structures discussed here cannot be produced using any traditional manufacturing process. Additive manufacturing is the only viable option, and the research in this field is sparse. We fill a gap in additive manufacturing and analysis of composite lattice structures. It adds to the existing knowledge that will prove valuable with carbon composite lattice structures increasingly used in real-world applications. We analyzed specimens using compression testing, impact loading, numerical simulations, microscopic imaging, and CT scans. We studied two different lattice topologies; open and closed cells. While open-cell lattices are suitable for lightweight and stiff structures, closed-cell lattices are ideal for energy absorption. Experimental results closely aligned with calculated data for open and closed cell lattice structures. A comprehensive review of related literature has been presented in each chapter to help the reader understand current and future trends. A detailed discussion of the future work will help anyone who wants to take this research forward.
