The scientific Committee has decided to award 2 lectures in 2007:
Christian Perotto Award 2007 attributed to : Marc COMET for his lecture on « Energetic nanocompositions for automotive safety devices »
Marc presented in a very clever way the work done in Institut de Saint –Louis on new energetic materials based on nano components. Paper and lecture were considered by the Scientific Committee as an important contribution to the future of energetic materials. The use of nano components and the consequences of its use on intrinsic performances of the obtained materials are promising and seem to be one major trend for a new step in automotive industry.
This paper illustrate the great work achieved by ISL on nano-particles.
Extract of the abstract :
The current advance in the field of the nanostructuring of materials allow elaborating energetic compositions containing nanoparticles. The reactive properties of several kinds of these new generation pyrotechnics were studied in the French German research institute of Saint-Louis (ISL).The first material described in this paper is a tungsten trioxide (WO3) based nanothermite, which exhibits an impressive reactivity. The second type of materials is made of nano sized AlxMoyOz phases which allow tuning the reactive characteristics such as the ignition delay time and the combustion rate. The third class of compositions contains nano diamond as a reducing agent. Such composition undergo an unconventional decomposition mechanism which is characterized by two combustion modes. The last category of pyrotechnics described herein corresponds to Gas generating nanothermites (GGNT). The pressure released by the combustion of GGNT is directly linked to their formulation process. The reactivity of all these materials was investigated by Time Resolved Cinematography (TRC), which is an advanced method routinely used at ISL to characterize the decomposition of energetic nanomaterials.
Christian Perotto Award 2007 attributed to : Manfred POCK for his lecture on « New plastic igniters made by Hirtenberger Automotive Safety”
Very dynamically, Manfred presented the development strategy of Hirtenberger and the technical solutions chosen to introduce on the market a new low cost igniter at highest technical level. Technical trend followed by Hirtenberger was the design of a Plastic igniter fulfilling AK-LV16. By this lecture Hirtenberger demonstrate is leading position in the development and supply of micro gas generators and igniters for the automotive market. Manfred Pock from his technical position in Hirtenberger made a high contribution to this technical success.
Extract of the abstract :
As the demand for low cost igniters increased, Hirtenberger Automotive Safety started to develop new technologies for the production of igniters, with characteristics as GTMS igniter. The result of this development, the HPP (Hirtenberger Plastic Pill) a plastic igniter, is a totally new concept for low cost igniters at the highest technical level. The HPP is based on a conventional fusehead which is already in use for several serial ballistic requirements of the latest AK-LV16 specification. This fusehead is overmoulded with a vapour and gas tight cover directly on the pyrotechnical components. This overmoulding guarantees a hermetic sealing of the pyrotechnics and allows a high level of integration in any application by moulding the electrical interface directly to HPP in further processing.
A core advantage of this type of igniter is the fact that both, leadwire- and pintype versions of e.g generators are supported. For pintype generators, different lengths of gold plated pins can be used, the pins are welded directly onto lamellas. Another benefit is that HPP igniter is also designed for low pressure applications, e.g activators with short strokes.
