Abstract
The bachelor’s thesis deals with the study of density and melting temperature
of polyethylene (LDPE, MD LDPE, HDPE). Polyethylene can be used as an ingredient
in paraffin fuels, which are utilized in hybrid rocket engines.
The theoretical part focuses on the description of thremal analysis methods and a basic characterization of hybrid rocket engine. An overwiew of the basic types of solid fuels
and oxidizers used in hybrid rocket engines is also provided.
The experimental part deals with determination of densities and melting points
of polyethylene samples. The stability of the samples during thermal analysis and the effect
of heating rate on melting points sre also studied. The obtained data are compared
with information from literary sources. The results are summarized in the conclusion
of the work.
