Abstract
This paper investigates a polymer composite and carbon fiber impregnated with epoxy resin for the fabrication of a lightweight and high-strength composite casing for rocket propulsion systems. It describes the winding technology which uses a removable mandrel and angular winding at ±55° and ±20° to expand the stress distribution, as well as alternating angles of ±45° and 80° to improve resistance to tensile and torsional loads. A fixture has been developed that ensures ease of disassembly and good strength of the final products. Hydrostatic tests showed the operational stability of the casings under internal pressure up to 10 MPa for a 1.5 mm-thick casing and 18 MPa for a 3 mm-thick casing, which confirms the effectiveness of the proposed technology. The research results demonstrate the high reliability and potential exploitation of composite materials.
期刊介绍：
Polymers (ISSN 2073-4360) is an international, open access journal of polymer science. It publishes research papers, short communications and review papers. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Polymers provides an interdisciplinary forum for publishing papers which advance the fields of (i) polymerization methods, (ii) theory, simulation, and modeling, (iii) understanding of new physical phenomena, (iv) advances in characterization techniques, and (v) harnessing of self-assembly and biological strategies for producing complex multifunctional structures.
