Evaluation of Engineering Plastic for rollover protective structure (ROPS) mounting.
Journal of agricultural safety and health, 2007Co-Authors: R. S. Comer, Paul D. Ayers, Juhua LiuAbstract:Agriculture has one of the highest fatality rates of any industry in America. Tractor rollovers are a significant contributor to the high death rate. Rollover protective structures (ROPS) have helped lower these high fatality rates on full-size tractors. However, a large number of older tractors still do not use ROPS due to the difficulty of designing and creating a mounting structure. To help reduce this difficulty, Engineering Plastics were evaluated for use in a ROPS mounting structure on older tractors. The use of Engineering Plastics around axle housings could provide a uniform mounting configuration as well as lower costs for aftermarket ROPS. Various Plastics were examined through shear testing, scale model testing, and compressive strength testing. Once a material was chosen based upon strength and cost, full-scale testing of the Plastic's strength on axle housings was conducted. Finally, a mounting structure was tested in static ROPS tests, and field upset tests were performed in accordance with SAE Standard J2194. Initial tests revealed that the ROPS mounting structure and axle housing combination had higher torsional strength with less twisting than the axle housing alone. An Engineering Plastic ROPS mounting structure was easily successful in withstanding the forces applied during the static longitudinal and lateral ROPS tests. Field upset testing revealed that the mounting structure could withstand the impact loads seen during actual upsets without a failure. During both static testing and field upset testing, no permanent twisting of the mounting structure was found. Engineering Plastic could therefore be a viable option for a universal ROPS mounting structure for older tractors.

Evaluation of Engineering Plastic for Rollover Protective Structures (ROPS) Mounting
2005 Tampa FL July 17-20 2005, 2005Co-Authors: R. S. Comer, Paul D. Ayers, Juhua LiuAbstract:The Agricultural Industry has one of the highest fatality rates of any industry in America. This death rate is largely due to deaths caused by roll over accidents while on agricultural vehicles. The addition of ROPS (Rollover Protective Structures) has aided in lowering these high fatality rates on full-size tractors. However, there are still a large number of older tractors that do not use ROPS, due to the difficulty of designing and creating a mounting structure onto pre-ROPS tractors. To aid in elimination of this difficulty, an evaluation of the use of Engineering Plastic as a mounting structure on pre-ROPS vehicles was conducted. The use of Engineering Plastics around axle housings could prove to create a uniform mounting style, as well as, lower costs of aftermarket ROPS for these vehicles. Various Plastic’s strengths were examined through shear testing and scale model testing. Once a material was chosen based upon strength and cost, full scale testing of the Plastic’s strength on axle housings was conducted. Finally, the mounting structure was tested in a static ROPS test done in accordance with SAE Standard J2194. From these tests, the usefulness of Engineering Plastics could be determined for mounting ROPS to tractors. Initial tests reveal that the torsional strength of the ROPS mounting structure is higher than the axle housing alone. The ROPS mounting structure was successful in withstanding the forces applied during the static longitudinal and lateral ROPS tests.

PEMERIKSAAN OPERASIONAL UNTUK MENILAI EFISIENSI DAN EFEKTIVITAS FUNGSI PENJUALAN PADA PT. TLOGOMAS ABADIJAYA Engineering Plastic INDUSTRY MALANG
2003Co-Authors: Draviana Luckyta SariAbstract:This is a case study at PT. Tlogomas Abadijaya Engineering Plastic Industry Malang entitles ?Operational Investigation to Evaluate an Efficiency and Effectivity Sale Function at PT. Tlogomas Abadijaya Engineering Plastic Industry Malang.? The purpose of this study is to find out the application of operational investigation on sale function at PT. Tlogomas Abadijaya Engineering Plastic Industry Malang and the efficiency and effectivity of its sale function. In this study, the discussion uses operational investigations steps involving: 1. Introductional Investigation, 2. Performing of Field Investigation, 3. Analysis Discussion, 4. Reporting and Recommendation. Analysis method used to find out the efficiency is ratio analysis, by comparing sale cost and sale return, while the method to find out its effectivity is sale variance analysis, it is comparing sale budget and sale implementation. Computational result from ratio analysis which compares budget and implementation in term of its sale cost and sale return suggests that in 1998 there is a decrease from 4.74% budget to 4.62% implementation and in 1999 from 4.56% budget to 4.51% implementation, then in 2000 from 4.19% budget to 4.13% implementation. It means that lower sale cost is more efficient, and it seems that the percentage of implementation is lower than its budget. The computational result using sale variance analysis in term of its effectivity suggests that there is a material difference during 2 years operation, in 1998 it is Rp. 2,124,400.00 and in 1999 is Rp. 6,045,500.00 and in 2000 the difference is not material (Rp. 3,566,300.00) so that it can be neglected. Based on the result of ratio analysis to find out its sale function efficiency, it suggests that the sale function of PT. Tlogomas Abadijaya Engineering Plastic Industry Malang is quite efficient, but variance analysis to evaluate the effectivity suggests that its sale function is not effective. Based on the conclusion above, it implies that PT. Tlogomas Abadijaya Engineering Plastic Industry Malang should routinely and periodically perform operational investigation so that the problems related to its sale function can be recovered, which in turn will lead to way of overcoming all problems and deviations and limitating company loss.

Novel sustainable biobased flame retardant from functionalized vegetable oil for enhanced flame retardancy of Engineering Plastic
Scientific Reports, 2019Co-Authors: Boon Peng Chang, Amar K Mohanty, Suman Thakur, Manjusri MisraAbstract:The flame retardancy of an Engineering Plastic, poly(butylene terephthalate) (PBT), with a biobased flame retardant (FR) made from phosphorylated linseed oil (PLO) and phosphorylated downstream corn oil (PCO) was studied. Different phosphorus moieties were incorporated into the vegetable oil backbone through a ring-opening reaction. The chemical structure of the phosphorylated oil was confirmed by Fourier-transform infrared (FTIR) and nuclear resonance magnetic (NMR) spectroscopy. It was found that the incorporation of only 7.5 wt% of PLO was sufficient to change the UL-94 fire class of PBT from non-rating to V-0. The flame-retardancy mechanism of the PBT/PLO blends was evaluated from TGA-FTIR analysis. The combined effects of the gas phase mechanism and the dripping tendency of the blends aided to retard the flame propagation effectively. As the synthesized PLO and PCO contained high free fatty acids, the acid-ester exchange reaction occurred in the blends to form oligomers during the ignition. As a result, the blend dripped immediately and the drips carried all the heat to prevent fire. This work suggests that this sustainable biobased FR could be a desirable alternative to halogen-based FRs for PBT and other Engineering polymers to develop more environmentally friendly FR products for various future applications.
