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.

Balancing Chain Transfer Agent Transport and Reaction in Emulsion Polymerization

Macromolecular Reaction Engineering, EarlyView.
The interrelationship between chain transfer agent mass transfer and reaction in emulsion polymerization is examined. Three parameters describing these phenomena are proposed. The probability of mass transfer‐ rather than reaction‐limitation for each CTA‐monomer pair is assessed.

Acrylonitrile Styrene Acrylate (ASA) With Optimized Aluminum Oxide (Al2O3) Nanofiller Content for MEX Additive Manufacturing: Thermomechanical, Rheological, and Quality Metrics

Polymer Composites, EarlyView.
Characterization processes for ASA/Al2O3 nanocomposites in MEX 3D printing. ABSTRACT As additive manufacturing (AM) continues to expand, the demand for durable components for outdoor applications is increasing. Acrylonitrile styrene acrylate (ASA), a weather‐resistant polymer, is widely used in these applications, and improving its performance could ...

Impact of Waste‐Derived Slate Dust on Structural, Thermal, and Thermomechanical Behavior of Recycled Poly(Ethylene Terephthalate)

Polymer Composites, EarlyView.
This study investigates the use of waste slate dust as a filler in recycled PET. Incorporating up to 20 wt% slate dust caused no filler‐induced molecular degradation, increased the crystallization temperature, thermal conductivity, and storage modulus. ABSTRACT Recycled polyethylene terephthalate (rPET) is widely considered a sustainable alternative to
