Corner Sealants For Tactical Shelters, Janine Carlita Nowak
Corner Sealants For Tactical Shelters, Janine Carlita Nowak
Honors Theses
The demand for a lightweight, easy-assembly tactical shelter is high for those faced with unexpected disasters and global conflicts. This project focuses on designing and prototyping the corner sealant for such a shelter. Two materials were chosen and tested: an in-house thermoplastic polyurethane (TPU) and Texin 950. Thermogravimetric Analysis (TGA) was performed on both of these materials. The in-house TPU showed initial degradation at 282.50 °C and sample degradation at 457.45 °C. Similarly, Texin 950 showed initial degradation at 293.68 °C and sample degradation at 453.26 °C. Differential Scanning Calorimetry (DSC) was then run. The crystallization temperature (Tc) was observed …
Characterization And Selection Of Hydroxyl-Terminated Polybutadiene Polymers For High-Strain Applications, Nathaniel Prine
Characterization And Selection Of Hydroxyl-Terminated Polybutadiene Polymers For High-Strain Applications, Nathaniel Prine
Honors Theses
Understanding the behavior of hydroxyl-terminated polybutadiene (HTPB) as a composite matrix is imperative for the development of future military and aerospace munition technology. As a vital component of solid rocket fuel, HTPB strongly contributes to the fatigue behavior, burn-rate, and other properties that can cause critical failure of the rocket if not formulated properly. The purpose of this research is to identify traits characteristic of poor-performing HTPB matrices by analyzing two samples labeled as either “good” or “bad” based on their performance as a fuel matrix. Samples were analyzed via 1H NMR and GPC to determine their epoxy content, hydroxyl …
