Mechanical Properties Evaluation Of 3d Printed Petg And Pctg Polymers, Kalpesh Krishnarao Bhosale
Mechanical Properties Evaluation Of 3d Printed Petg And Pctg Polymers, Kalpesh Krishnarao Bhosale
Electronic Theses and Dissertations
3D printing is also known as additive manufacturing (AM) which has become a popular manufacturing trend over the years. Due to its unique advantages of fast production rate, ability to create complex geometrical features, toolless manufacturing and many more attracts various industries from Aerospace to general cosmetics. Along with the advancement in material science, various polymers including Polylactic Acid (PLA), Polyethylene terephthalate glycol (PETG) and many more are available for 3D printing. Due to the wide range of applications in PLA, it is necessary to improve its toughness to make it more suitable by adding Poly Cyclohexylenedimethylene Terephthalate glycol (PCTG) …

An Experimental Study On The Mechanical Properties And Chemical Composition Of Lcd 3d Printed Specimens, Sebastian Gomez
Electronic Theses and Dissertations
Additive manufacturing technologies have been enhanced throughout the years yet have surprised the manufacturing industry due to their high-end surface finish and dimensional accuracy. Different experiments have been done to identify a specific phenomenon known in the vat-polymerization field. Distortion and dimensional inaccuracy tend to affect the overall properties of the process, either physical or chemical. This approach allows the understanding of how the physical properties have been affected and how to study the chemical properties to avoid this type of phenomenon. The chemical reaction between polymer and UV light has been studied and experimented with to the point that …
Development Of Corn Kernel-Based Biocomposite Films For Food Packaging Applications, Swastika Bera
Development Of Corn Kernel-Based Biocomposite Films For Food Packaging Applications, Swastika Bera
Electronic Theses and Dissertations
Most of the current and active food packaging resources and methods are nonbiodegradable and nonrenewable therefore harmful to the environment. Due to this, alternate sources of food packaging materials are in high demand. In this study, a bio-composite film has been developed, with Corn kernel powder as fiber reinforcement which is mixed with gelatin, and lignin two biopolymers as the matrix. The effect of Corn Kernel (CK) reinforcement on the Gelatin/Lignin (G/L) matrix on mechanical and barrier properties has been studied. CK has shown great potential as reinforcement to natural polymer, gelatin, and lignin (G/L) for food packaging applications as …
On The Simulation Of Supersonic Flame Holder Cavities With Openfoam, Zachary Chapman
On The Simulation Of Supersonic Flame Holder Cavities With Openfoam, Zachary Chapman
Electronic Theses and Dissertations
One of the next major advancements in the aerospace industry will be hypersonic flight. However, to achieve hypersonic flight, propulsion systems capable of reaching hypersonic speeds need to be developed. One of the more promising hypersonic propulsion systems is the scramjet engine, however, several problems still need to be explored before reliable scramjet engines can be produced, the biggest being keeping the engine ignited. This has led to the use of flame holder cavities to create a region of subsonic flow within the engine to allow combustion to occur. High experimental costs make the use of computational fluid dynamic (CFD) …
