Vibration Assisted Injection Molding: An Innovative Energy Efficient Processing Technique for Poly-Lactic Acid (PLA) with Enhanced Properties

Coulter J.P., Duhduh A., Gao P., Kundu A., Xing J., Lehigh University, US

This work is focused on the development of time and energy efficient injection molding processing strategies to fabricate semi-crystalline plastic components with enhanced properties. A Vibration Assisted Injection Molding (VAIM) process was devised for this [...]

Vibration Assisted Injection Molding for PLA with Enhanced Mechanical Properties and Reduced Cycle Time

Coulter J., Duhduh A., Gao P., Kundu A., Lehigh University, US

Vibration assisted molding (VAIM) is a process in which vibrational movement is introduced to the injection screw during the injection stage of molding processes. This research was focused on the effect of processing parameters on [...]

Shear Induced Crystallization through Altering Flow Area of Polymer Melt in Additive Manufacturing

Alqosaibi K., Coulter J., Duhduh A., Kundu A., Noor H., Lehigh University, US

Additive manufacturing is a new paradigm of fabricating products. The ability to build near-net shapes by depositing layer by layer in additive manufacturing have provided a time and energy efficient processing strategy whose full potential [...]

Mechanical Properties of 3D Printed PLA Specimens with Various Infill Shapes and Volumes

Arifa K., Asmatulu E., Rahman M.M., Subeshan B., Wichita State University, US

Traditional manufacturing methods contain removing excess materials by trimming, cutting and sanding to get the projected shapes; however, additive manufacturing contain direct manufacturing of the objects utilizing computer assisted design model by adding a layer [...]

Functional Multi-layered Bio-scaffold by 3D printed and Electro spun biodegradable materials

Choi H.W., Keimyung University, KR

In paper, we are presenting a novel technology for the bio-scaffold fabrication. The fabricated scaffold is composed of 3 layers which include a 3D printed PLA in middle and electro spun nanofibers of PCL+Collagen on [...]

Mechanical Properties of PLA-Jute Composites by Using Natural Rubber and Epoxidized Natural Rubber as Impact Modifiers : Effect of Molding Technique

Kluengsamrong J., Ruksakulpiwat Y., Tonimit P., Suranaree University of Technology, TH

Jute fiber was used as a reinforcing fiber in poly (lactic acid) (PLA) composites. Natural rubber (NR) and epoxidized natural rubber (ENR) are used as impact modifiers of jute-PLA composite. The composite specimens were prepared [...]

Enhancement of Defect Tolerance in the QCA-based Programmable Logic Array (PLA)

Miura K., Nakamae K., Notsu T., Osaka University, JP

In this study we analyze the precedent AND/OR plane cell of a programmable logic array (PLA) based on the quantum-dot cellular automata (QCA), then propose a modified layout that has better defect tolerance. We analyzed [...]

Preparation And Evaluation Of In Vitro Release Of Amphiphilic _-Cyclodextrin Or Pla Nanospheres Containing A Hydrophobic Drug

Lahiani-Skiba M., Lin S., Naouli N., Skiba M., Université de Rouen, FR

Mebendazole (MBZ) is an antihelmintic which belongs to group of benzimidazols. It is used for many intestinal diseases and for other diseases. But its low absorption, its high dosages caused side effects on gastro-intestinal track, [...]
