Development Of Waste-Based-Thermoplastic Composite Heat Insulators, Waseem Yousef Hittini
Development Of Waste-Based-Thermoplastic Composite Heat Insulators, Waseem Yousef Hittini
Mechanical Engineering Theses
The main scope of this research is to develop polymer-filler thermal insulators utilizing natural and industrial local waste such as date pit powder (DPP), devulcanized tire rubber (DVR), and buffing dust (BD). Recycling and reuse of these local wastes as fillers in insulation materials has significant benefits for the UAE environment. An objective of this work was to study the effect of the combination of these local wastes with polystyrene (PS) on the physical, mechanical, and thermal properties of the developed thermal insulators. PS was used as a matrix, mixed in different proportions with the waste fillers. Each mixture was …

Thermomechanical Characterization Of A Shape Memory Polymer Based Syntactic Foam, Damon Nettles
LSU Master's Theses
Shape memory polymers (SMPs) are a type of smart material capable of “remembering” multiple shapes and transitioning between them in response to an external stimulus. They offer the potential to self-seal macro-length scale damage in a nearly autonomous fashion. Syntactic foams are lightweight structural materials currently used in the marine and aerospace industries. This study seeks to bring syntactic foams and SMPs together, retaining characteristics of both components, to create a low-density smart composite. The SMP based syntactic foam is used as the core of a grid stiffened sandwich structure capable of healing impact damage multiple times. In order to …
