| Abstract Scope |
Beam and plate lattice structures have been widely used to reduce the mass of additively manufactured structures. Likewise, carbon fiber composite materials are of considerable interest for specific strength and stiffness properties. This presentation focuses on the relatively new Composite Based Additive Manufacturing (CBAM) process which is categorized as a sheet lamination AM method. The study specifically uses a carbon fiber (CF) composite reinforcing phase with a PEEK polymer matrix to produce body centered cubic plate lattices. These lattices normally have void space between the solid plates. With CBAM, however, the void space is occupied by carbon fiber without any PEEK matrix material. Most of the composite material's mass comes from the PEEK matrix rather than carbon fiber, hence the structure's mass is still reduced by 40-45% versus completely solid composite material. Compression and flexural properties of plate lattice structures relative to solid carbon-PEEK composite material will be reported. |
