Design development and technology synthesis for the production of
cellular hybrid plastic structures for application in acoustic resonators

In the course of the Hybsch project, the Institute of Lightweight Structures Period
and Polymer Technology at the TU Dresden is striving to develop novel cellular 01.04.2021 – 31.03.2023
core structures. For this purpose, the integration of flexible walls enables the
targeted application of the core in acoustic liners for the reduction of sound Project management
emissions. Furthermore, the integration of fiber-reinforced tapes increases Prof. Dr.-Ing. Niels Modler
the compressive strength compared to similar core structures.

In this context, the manufacturing realization of the hybrid core structure Moritz Neubauer
within a continuous process is investigated, taking into account the struc-
tural-mechanical as well as acoustic specifications. Thereby, the sub-process Funding
steps of the tape application, the partial cutting as well as the forming are Funded by
examined in detail. The work done so far focused on the development and
description of cellular curved core structures suitable for continuous man-
ufacturing. In addition, a structural mechanics analysis of cell configurations German Research Foundation
with varying characteristics of the reinforcing structure has been carried out.
In experimental analyses, the process steps “tape application” and “forming” German Research Foundation (DFG)
were investigated and suitable process parameters were defined. Project number: 416814415
