Other specifications
In order to continuously improve the safety of all people involved in road traffic (passengers, pedestrians, cyclists), further developments in safety systems are essential. The safe functioning of the safety device is of particular interest in the case of pyrotechnic items.
Thanks to its extensive expertise in the field of damage analysis and airbag or airbag propellant field events and its modern testing facilities, workshops and laboratories, GWP mbH is able to provide valuable contributions and insights into your new or further development right from the early stages of product development. In addition to established testing procedures, e.g. according to OEM specifications or standards, GWP mbH can also carry out its own innovative tests in order to find the right answer to the questions of the respective development.
usage and service life
The lifetime of occupant protection systems is a major concern in the design and procurement of equipment – especially those containing pyrotechnic formulations such as airbag inflators, seat belt pretensioners and actuators. Artificial ageing, as provided for in current standards, allows an estimate of product lifetime. However, it often reaches its limits when it comes to predicting the safe lifetime of pyrotechnic compositions. Complications in age prediction arise from the non-trivial chemical processes involved in the ageing of fuel materials. The multitude of environmental influences and vehicle-dependent design differences require a multitude of assumptions and simplifications that lead to discrepancies between prediction and reality.
The GWP is able to make well-founded statements on chemical compatibility, possible degradation and error paths through targeted investigations tailored to the new development (e.g. propellant charge, gas generator design, etc.). This means that developments can be optimized and error paths eliminated in good time at an early stage - a benefit for manufacturers, OEMs and consumers!
GWP's expertise in simulating a wide range of environmental and disruptive influences is an advantage for customers when it comes to carrying out efficient simulations, obtaining reliable data and gaining sound insights from them
