Hybrid lattice structure made of AM thermoplastic polymer and CFRP ligaments
As opposed to thermoset matrix systems, thermoplastic polymers may be remelted. This characteristic opens the possibility for joining and reshaping CFRP laminates, to increase the geometrical complexity of composite struc-tures. In the case of this project, it is intended the hybridi-zation of fully thermoplastic nodes with axially stiffer Car-bon Fiber Reinforced Polymer (CFRP) ligaments. This aims to allow the selective deformability of meta-material inspired structures (metastructures).
This thesis relies on the joining possibility of thermo-plastic-based composites to realize hybrid thermo-plastic/CFRTP. The ligaments are formed using CFRTP and are used to join additively manufactured thermoplas-tics nodes.

The first step of this project is the get familiar with thermoplastic-based composites processing, and the state of the art in joining and reshaping. As a second step, a pro-cessing technique for the joining of CFRTP to additively manufactured thermoplastic nodes. A demonstrator is to be manufactured. For this demonstrator, the size, geometry, and number of ligaments per node are to be determined according to an external load case given.
