Experimental Investigation and Design Analysis of Hollow Glass Microsphere loaded PP/ABS Composites

The objective of the present is to investigate hollow glass microspheres (HGMs) experimentally and carry out design analysis of hollow glass microsphere loaded PP/ABS composites. The tensile and notched Charpy impact test of HGM-filled acrylonitrile-butadiene-styrene copolymer (ABS) and Polypropylene (PP) composites will be studied with varying the concentrations of PP/ABS composite with HGM. Also further the design analysis will be studied by conducting the simulation under the same criteria and comparing the results at the end. This is done to introduce a light weight material without compromising specific strength of PP/ABS composite by adding HGM to the composite. Keywords: Hollow Glass Microsphere (HGM), ABS-Acrylonitrile butadiene styrene, PP- Polypropylene, Composites.

Study on the efficiency of a transducer for sonochemistry by calorimetry

Sonochemistry is an effective method for initiation or enhancement of the chemical reactions by ultrasound in a wide range of applications. In this study, the efficiency of a sonochemistry transducer, defined as the ratio of ultrasonic power to electrical power, was investigated for different materials and the thicknesses of the vibration plate in the frequency range 22 kHz–2 MHz. The ultrasonic power was measured by calorimetry. To eliminate the influence of reflected waves, the transducer was attached to the side of a cylindrical vessel. The transducer with a stainless-steel vibration plate was more efficient than those with vibration plates of acrylonitrile butadiene styrene plastic or chloroprene rubber. The efficiencies of the transducers also increased with decreasing thickness of the vibration plates. Langevin-type transducers were less efficient than the disk-type transducers.

Analysis and Optimization of UAV Frame Design for Manufacturing from Thermoplastic Materials on FDM 3D Printer

Thermoplastic materials have great usage through FDM 3D printing technology. Today, FDM 3D printer is available to the broad population, and some of the thermoplastic materials is widely used due to their small price and availability. Such thermoplastic materials are ABS (Acrylonitrile butadiene styrene) and PLA (Polylactic acid). In this paper the possibility of drone frame design optimization that can be made from ABS and PLA plastics using FDM 3D printing technology is analyzed.
