Beschreibung

Fiber-reinforced polymer (FRP) composites, renowned for their exceptional strength-to-weight ratio, are increasingly
employed as load-bearing structural elements in both the aerospace and automotive sectors. In
recent years, both industries have witnessed a growing demand for composite overwrapped pressure vessels
(COPVs), driven by economic, environmental, and competitive considerations. This rising demand has not only
intensified market competition but also elevated the technical and regulatory requirements associated with
these components. Consequently, new challenges have emerged across the entire value chain. To address
these evolving demands and to enable further innovation and optimization, a comprehensive understanding of
the design, development, and manufacturing processes of COPVs is essential.

In this research, the effects of various manufacturing parameters - such as fiber tension, winding time, winding
patterns, and variations in the curing process - will be investigated with respect to compaction and void content.
Newly manufactured filament-wound structures produced under different parameter settings, chosen after
a literature review, will be analyzed alongside existing components. To ensure scientifically reliable imaging,
all samples will be prepared through resin embedding and sanding. The subsequent microscopic analysis will
focus on key parameters, including cured ply thickness, fiber undulations, and fiber volume fraction. These
findings will be interpreted and benchmarked against results from the literature, compared with existing
strength data, and potentially validated through additional structures that will be manufactured and tested in a
later phase of the research.
