Ultrasonically welded and non-welded polypropylene and PC-ABS blend thermal analysis
Automobile industries are focusing toward the reduction in the weight of vehicle that leading to cost reduction and improving the fuel efficiency. Polymers are the main alternatives in conventional engineering materials for automobile components due to their advanced mechanical and thermal properties. This article is mainly focused on the ultrasonic welding of polypropylene and PC-ABS materials followed by thermal analysis of injection-molded and welded specimens. The materials are examined by an advanced analysis method called differential scanning calorimetry. The crystalline nature of the material is changed (area varies from 95.1 to 115.4 J g−1) at injection-molded regions in polypropylene differential scanning calorimetric results. After polypropylene welding, the glass transition temperature values tend to change from 5 to 10 K min−1 heating ranges. In PC-ABS blend, the glass transition temperature is changed from 126.3 to 127.0 °C in the non-welded material. From the welded PC-ABS material results, it is evident that the difference between 5 and 10 K min−1 heating value is only 1.8 °C. Finally, the finite element analysis is carried out to examine the materials deformation pattern with temperature loading.
