Plastics are prone to photo oxidative and thermal oxidative degradation under usage conditions due to their chemical nature. From sustainability and cost standpoint, there is an increasing focus on Mold-In-Color (MIC) plastic materials. Simultaneously customer’s expectations on the perceived quality of these MIC parts has been increasing with attractive color and glossy appearance. A study was conducted to analyze the product quality and durability aspects over a prolonged exposure to accelerated weathering condition. Material selected for this study were injection molded specimens of ABS and PC/ABS used in automotive passenger vehicles. Comparative analysis was conducted before and after weathering exposure at defined intervals by using the various tools like Fourier Transform infra-red spectrometer (FTIR), thermogravimetric analyzer (TGA) and universal testing machine (UTM), Izod impact tester, dynamic mechanical analyzer (DMA) to understand the impact on their chemical and mechanical properties. This study will be useful in understanding material behavior, durability, performance and product quality.

Squeak and Rattle (S&R) are the dominant undesired noises which adjudge the perceived quality of a vehicle. It's a foremost problem which needs to be identified and eliminated at a design stage to develop a robust vehicle, which also aids in pacifying the physical testing and warranty claim costs. A Finite Element model of the complex plastic dashboard has been analyzed to identify risks and the root cause of S&R problem under dynamic and static loading conditions, using E-line methodology. These complex transient problems are highly influenced by various parameters like gap variability, temperature, the coefficient of thermal expansion, thickness, and material properties. This paper elaborates the detailed investigation conducted using stochastic simulations to evaluate the individual and combined impact of each parameter on S&R performance

To be published on 2019-11-21 by SAE International in United States
The Automotive industry is in ever more need for a lesser weight car due to progressively stringent emission norms and the demand of customer to have better mileage. It can be a gargantuan challenge for automotive manufacturers to search for lesser weight material to meet both customers as well as regulatory norms. But in some cases such lower weight material can increase the cost and adding a expensive material which increases overall cost to a price sensitive market like India is not favorable. One such solution is using the indigenous plant fiber (Jute) in combination with propylene (PP) to make Interior plastics components. Jute a vegetable fiber also referred to as "the golden fiber" has high tensile strength, low extensibility and is well established in fabric, packing, agriculture, construction industries. The biodegradable Jute lesser weight & abundance (India is the leading manufacturer of the Jute) can be utilized in making automobile trim parts in India. Through this paper we will have insight of the natural fiber based plastic components the benefits (lesser weight, Less GSM…

Published 2019-10-11 by SAE International in United States
Utilization of diesel is augmented consistently by transportation and industrial sectors which is making its existence obsolete in near future. Tremendous research has been done by many researchers to find an appropriate alternative for diesel fuel, in this scenario abundant acquisition of plastic wastes and their improper retreating techniques has grabbed the attention of researchers to convert them into alternative fuel for IC engines. This experimental investigation aims to study the performance, combustion and emission characteristics of common rail direct injection (CRDI) fuelled with waste plastic oil and diesel blends at different injection strategies and at various loading conditions. From the results it is noticed that slight decline in the thermal efficiency of the engine when operated with waste plastic oil (100%) due to high viscosity and lower heating value. There was a momentous diminishment in NOx emissions for low injection pressures of plastic diesel blend (P30). This study shows that waste plastic oil blend can be successfully used as fuel in the diesel engines without any considerable modifications.

Experimental Study on Tool Wear and Cutting Temperature during Machining of Nimonic C-263 and Waspaloy Based on Taguchi Method and Response Surface Methodology

Sri Sairam Engineering College-Vetri Velmurugan Kannan

Published 2019-10-11 by SAE International in United States
Nickel based materials of Nimonic C-263 and Waspaloy are used nowadays for aerospace applications owing to its superior strength properties that are maintained at a higher temperature. Tool wear and cutting temperature in the vicinity of cutting edge are two essential machinability characteristics for any cutting tool. In this regard, this study is pursued to examine the influence of factors on measuring of tool wear (Vba) and cutting temperature (Ts) during dry machining of two alloys studied experimentally based on Taguchi method and response surface methodology. Taguchi’s L16 orthogonal array is used to design the experiment and a PVD (TiAlN), CVD (TiN/Al2O3/TiCN) coated carbide inserts are used on turning of two alloys. The factor effect on output responses are studied using analysis of variance, empirical models, and responses surface 3D plots. To minimize the response and to convert into one single optimum level, responses surface desirability function approach is applied. The results show that progress of flank wear associated with Waspaloy is faster that of Nimonic C-263 due to high cutting temperature for Waspaloy that…

Mahindra & Mahindra, Ltd.-Praveen Kumar, Ramakrishna Nimmagadda, Harshad Bornare, Nareen Kinthala
Published 2019-10-11 by SAE International in United States
With increasing road traffic and pollution, it becomes responsibility for all OEM to increase fuel efficiency and reduce carbon footprint. Most effective way to do so is to reduce weight of the vehicle and more use of ecofriendly recyclable material. With this objective we have come up with Light weight, cost effective sustainable design solution for Injection moulded RQT (Rear quarter trim). It is an interior plastic component mounted in the III row of the vehicle. This is required to ensure inside enhanced aesthetic look of the vehicle and comfort for 3rd row passengers. Conventionally RQT of vehicle with 3rd row seating is made using plastic material (PP TD 20). With the use of plastic moulded RQT there is a significant weight addition of around 6 kg per vehicle along with reduced cabin space, huge investment and development time impact.In PROJECT X model which is a 4.4 meter vehicle with 3rd row seating capacity, we have challenged the conventional way of design and have come up with “Light weight, cost effective sustainable design solution” of…

Published 2019-10-11 by SAE International in United States
Experimental investigations carried out in a diesel engine incorporated with Exhaust gas recirculation (EGR), fuelled with the blend of diesel and plastic oil along with an antioxidant additive (p-Phenylenediamine) are presented in this paper. Plastic oil is produced from waste plastics through the process of pyrolysis which could be a potential substitute to fossil diesel in diesel engine applications. Production of plastic oil provides solution to the global twin problems of plastic waste management and energy crisis. Investigations have been carried out with the test fuel separately, test fuel with the additive, test fuel with incorporation of EGR in the engine and test fuel with additive and EGR incorporation. Test results revealed that blend of diesel and plastic oil exhibited performance and emissions at par with pure diesel, 18% reduction in NO emission through EGR incorporation as compared to without EGR and 15% reduction in NO through use of antioxidant additive. It is found that the combined effect of EGR incorporation in the engine and antioxidant additive to the test fuel is a drastic reduction…
