Thermal and mechanical properties of rocket motor liners
Benli, Salih; Yılmazer, Ülkü; Özkar, Saim; Department of Chemical Engineering (1997)
Rocket motor liners are usually chosen from filled elastomers. The primary function of the liner layer is to bind the propellant grain to the motor case. A rocket motor liner also serves as a thermal insulator and burning inhibitor during the operation of the rocket motor. The primary objective of this study was to make thermal and mechanical characterization of polyurethane based rocket motor liners, and develop new liner compositions with optimum thermal, mechanical and processing properties. In the first...

Thermal and dynamic mechanical properties of microwave and heat-cured poly(methyl methacrylate) used as dental base material
Muhtarogullari, IY; Dogan, A; Muhtarogullari, M; Usanmaz, Ali (Wiley, 1999-12-13)
In this study, the particle size distribution, molecular weight, thermal analysis (TGA) differential scanning calorimetry (DSC) and thermogravimetric analysis, and dynamic mechanical analysis (DMA) of poly(methyl methacrylate) used as dental base material were investigated. The commercial raw material used were prepared for microwave curing, and they were cured by microwave and conventional heat methods. The average particle size of the powder studied (103.1 mu m) were much larger than that of the commercia...

We solve the Schrodinger wave equation for the generalized Morse and cusp molecular potential models. In the limit of high temperature we, first, need to calculate the canonical partition function which is basically used to study the behavior of the thermodynamic functions. Based on this, we further calculate the thermodynamic quantities, such as the free energy, the entropy, the mean energy and the specific heat. Their behavior with the temperature has been investigated. In addition, the susceptibility for...

The single-pellet moment techniques previously developed for the evaluation of effective diffusion coefficient and effective thermal conductivity of a porous solid are combined and a procedure is proposed for the simultaneous evaluation of these constants from a single set of pulse response experiments. It is shown that both temperature and concentration response curves can be measured from a single pulse of oxygen injected into hydrogen carrier gas flowing past a catalyst pellet. It is shown that the zerot...
