Performance based packaging standard for lithium batteries as cargo on aircraft

2016-03-18
WIP
AS6413
This standard is intended to demonstrate and document the control of the potential hazards from lithium cells or batteries (UN 3090 and 3480) when transported as cargo on aircraft. [still need to identify if we are addressing global (external fire) or local (battery internal failures)] This standard addresses the need to control the hazards which might arise from a failure from an individual cell by containing the hazards within the package. This specific hazards addressed within this standard are: • Uncontrolled fire • Rapid overpressure pulse within compartment

Surface Treatments and Characterization of Electroplated and Hot Dip Galvanized Steel Sheets

1996-04-01
91A126
Protection of surfaces is a critical factor in determining the extended service life of a structure in polluted and aggressive environments. In particular, a rapid growth of the technology for the protecting coating of cold rolled steel is experienced, for the use in transport, electric housewares, building and industrial plants. Numerous changes have taken place in the production of zinc coatings on steel in order to improve the corrosion resistance using zinc alloy platings. Our research group collected from the international production a number of selected galvanized steel samples, including electrodeposited zinc alloys, multilayer coatings, hot dip galvanized steels. On the selected materials we established and analyzed morphology, composition, crystal structure, impurity content and distribution, using many surface microanalysis techniques.

Recycling Potential of Polymers

1996-04-01
91A123
In order to reduce the volume of waste in general and of shredder waste from the disposal of scrap cars, the German Federal Government has prepared a draft regulation, which will be implemented unless the automotive industry and the distributors of imported cars take action on their own to achieve these objectives. The regulation provides that the car manufacturers are fully responsible for the environmentally controlled disposal of scrap cars. The return of scrap cars to the work industry must be free of change for the last owner. A nation-wide network for the return of scrap cars must be implemented by end of 1993. To reduce the amount of shredder waste the automotive industry is expected to practice recycling on non-metallic materials. Facilities required for thermal treatment of residues, which cannot be recycled, are to be installed on account of the originator, i.e. the automotive industry.

New Materials and Experiences for the Industrialization of Pu Structural Rim Technology

1996-04-01
91A122
Processes involving use of reactive polymers received recently considerable attention also for producing components suitable for automotive structural applications. In particular polyurethane structural RIM technology seems to be the route of choice in terms of productivity, reliability and physico- mechanical performances in order to fit the automotive industry needs in the production of parts requiring superior load bearing properties. In this frame the development of long pot life snap-cure resins, fast and effective reinforcement preforming techniques as well as the development of computerized provisional processing methodologies are of paramount importance in view of industrialization of the technology. In this paper a description of the work carried out by Enichem Montedipe and Montedison is given. In particular a new family of PU systems, based on special isocyanate variants, is reported.

Recycling Automobiles: a Problem of Environment and Resources

1996-04-01
91A130
The socio-economic system is coming to the conclusion that the environment will no longer tolerate and absorb all of man's interventions, and that natural resources no longer constitute a cheap and inexhaustible source of wealth. In this scenario of the limits of nature and ever-increasing environmental costs, we are faced with the problem of recovering and reusing the materials which go into the manufacture of an automobile. The replacement of metal materials with polymer materials leads to a reduction in the re-usable waste, and to an increase in the amount of waste with no economic value, or even with a negative economic value. The use of the non-ferrous and non-aluminous materials in an automobile is beyond the capabilities of new techniques for scrapping automobiles, which means that at the end of their lives, the automobiles must be disassembled, sorted on the basis of the constitute materials, recovered and recycled.

Application of Shape Memory Heat Engines to Improving Vehicle Fuel Economy

1996-04-01
91A128
Shape memory materials undergo temperature-induced martensitic phase transformations that involve reversible dimensional changes. In performing these changes in shape, the shape-memory material is able to do work against external constraints, and this is the basis for shape-memory low-temperature heat engines. The transformation temperatures on heating and cooling are often not very different (little hysteresis) and are well defined and reproducible. Furthermore, these temperatures can be adjusted by varying the composition of the shape memory alloy. Internal combustion engines dissipate approximately two-thirds of the fuel energy as heat to the exhaust and coolant systems. A low-temperature heat engine could convert a fraction of this heat energy to useful work. This paper discusses the conceptual basis for the application of shape memory heat engines to internal combustion engine powered vehicles. Metallurgical and thermodynamic factors are discussed, as well as engine efficiency.

The Modeling of Mold Filling in Structural Reaction Injection Molding

1996-04-01
91A118
The main use of FRC in automobiles, with the exception of a few specialized low volume vehicles, has been until now in semistructural parts. One of the most promising process in development today, that may play major role in future structural composite fabrication, is based on SRIM technology. The rapid and extensive introduction of this process goes also through the development of deeper theoretical knowledge of the process and the development of computer simulation to aid mold design and choice of proper processing parameters. To contribute SRIM advancement, a preliminary model has been developed for viscosity changes, extent of the reaction and temperature rises, associated with the mold filling stage, as well as a simple software to evaluate the pressure drop through different combinations of reinforcements.

Simulors, An Innovative Tool for Molds Development

1996-04-01
91A117
Mold designers and foundrymen spend a lot of time in developing molds without knowing exactly the phenomena which take place inside. Simulor, which has been used in an industrial environment for two years, offers the solution to make foundrymen understand what happens during the filling of the mold and the solidification of the part. Based on navier-stokes and heat transfer equations, simulor provides speed distribution and metal front evolution in the cavity and thermal map in the mold and the part. Some examples with different metals (cast iron, aluminum alloy) cast with various processes (sand or die casting, low pressure or gravity casting) will be given. This new tool will given foundrymen the opportunity to test the mold before having it machined and will also allow reduction in development delays.
