Research Study Concerning the Structural Design of a Drone Using 3D Print Technology

Macromolecular Symposia, EarlyView.
ABSTRACT The frame of a drone serves as support to hold in place all the key components of the drone, such as the battery, controller board, motors, and all the modules needed for different projects. In the industry, the drone frame is CNC machined from a block of material, or in some cases it is made of composite materials, carbon fiber, and ...

Experimental Comparison of Impact Behavior in Thin Carbon Fiber Reinforced and 3d Printed Polymeric Plates

Macromolecular Symposia, EarlyView.
ABSTRACT This study presents a comparative investigation of the low‐velocity impact behavior of thin plates made from carbon fiber reinforced polymer (CFRP), polylactic acid (PLA), and acrylonitrile butadiene styrene (ABS). Plates with nominal thicknesses of 0.5 and 5 mm were subjected to standardized drop‐weight impact tests to evaluate their energy ...

Infill Percentage on the Roughness of the Contact Surface Between 3D Printed Plastic Parts and the Platform

Macromolecular Symposia, EarlyView.
ABSTRACT Currently, interest in 3D printing technology has increased significantly. Fused deposition modeling (FDM) has become the most popular method, but obtaining optimal results requires special attention in the choice of manufacturing parameters.

Field‐Cycling NMR Relaxometry in Tire Elastomer Science

Magnetic Resonance in Chemistry, EarlyView.
Field‐cycling NMR relaxometry has established as an ideal tool to investigate multiscale polymer dynamics. Here, we review and discuss applications on elastomers and elastomer compounds of interest for the tire industry to obtain information on segmental dynamics and on polymer dynamics over different regimes as a function of chain length in polymer ...

Antimony Tin Oxide as a Nano Reinforcement Component for Acrylonitrile Styrene Acrylate in Material Extrusion Additive Manufacturing: Rheology and Thermomechanical Scores

Polymer Composites, EarlyView.
ASA/ATO nanocomposites in MEX 3D for outdoor applications. ABSTRACT In this study, the influence of incorporating Antimony Tin Oxide (ATO) filler into the Acrylonitrile Styrene Acrylate (ASA) pure polymer matrix was investigated, focusing on the mechanical, thermomechanical/thermochemical, and overall quality of 3D printed ASA/ATO nanocomposites.
