Mechanical and burning properties of highly loaded composite propellants
Gocmez, A; Erisken, C; Yılmazer, Ülkü; Pekel, F; Özkar, Saim (1998-02-22)
An improvement in the performance of solid rocket motors was achieved by increasing the oxidizer content of HTPB-based solid propellants. To minimize the adverse changes in the mechanical and rheological properties due to the increased amount of hard solid particles in the soft polymeric binder matrix, the optimum combination of the particle sizes and volume fractions of the bimodal ammonium perchlorate and the aluminum powder in the solid load was obtained from the results of testing a series of propellant...
Mechanical Properties of FeCoCrNi High Entropy Alloy (HEA) Produced from Industrial Raw Materials by Induction Melting
Erdal, Anıl; Polat, Gökhan; Kalay, Yunus Eren (null; 2018-11-25)
Equimolar FeCoCrNi high entropy alloy (HEA) was produced from industrial raw materials which were not pure and contain various impurity elements such as Al, Si and C by induction melting in order to investigate mechanical properties of the alloy. This alloy was casted into compressed steel mold that let us to produce mechanical test samples. XRD (X-Ray Diffraction) and SEM (Scanning Electron Microscopy) were used for structural characterization of the samples. Brinell hardness test was applied for mechanica...
Mechanical and thermal properties of thermotropic liquid crystalline copolyester (tlcp) and its mixtures with poly(ethyleneterephthalate) and denture base poly(methyl methacrylate)
Öztürk, Hale Bahar; Usanmaz, Ali; Department of Polymer Science and Technology (2004)
In this study, the thermal and mechanical properties of poly(ethylenetheraphthalate) (PET)-thermotropic liquid crystal polyester (TLCP), mixtures and poly(methyl methacrylate) (PMMA)-TLCP mixtures were studied. The curing of PMMA-TLCP mixtures was done by heat, gamma radiation and microwave. The amount of TLCP in mixtures was % 0.5, 2 and 5 TLCP by weight. TLCP was synthesized by melt-acidolysis system, and PET-TLCP mixtures were prepared by using lab scale batch mixer. PMMA samples were prepared according ...
Mechanical properties of thermoplastic parts produced by fused deposition modeling: a review
Bakir, Ali Alperen; Atik, Resul; Özerinç, Sezer (2021-02-01)
Purpose - This paper aims to provide an overview of the recent findings of the mechanical properties of parts manufactured by fused deposition modeling (FDM). FDM has become a widely used technique for the manufacturing of thermoplastic parts. The mechanical performance of these parts under service conditions is difficult to predict due to the large number of process parameters involved. The review summarizes the current knowledge about the process-property relationships for FDM-based three-dimensional prin...
Mechanical, flow and electrical properties of thermoplastic polyurethane/fullerene composites: Effect of surface modification of fullerene
Tayfun, Umit; KANBUR, YASİN; ABACI, UFUK; GÜNEY, HASAN YÜKSEL; Bayramlı, Erdal (2015-10-01)
Thermoplastic polyurethane (TPU) composites with fullerene loadings varying from 0.5 to 2 weight% were prepared by melt-mixing method. Nitric acid oxidation and silanization were applied to fullerene surface to improve interfacial interactions with TPU matrix. The influence of surface modifications of fullerene on mechanical, melt flow and electrical properties of TPU based composites were investigated. Incorporation of fullerene leads to nearly twofold increase in tensile strength and Young's modulus of th...
