Test of environmental parameters are key features of the missile flight testing, usually including acceleration, temperature, stress and strain, as well as structural response/action signal, these data stored in the data storage module in a digital way. So data storage module is the core device need to protect of the whole test system in such as launch / separation / ejection and touch to the impact environment. Introduced protection technology based on composite buffer module, the buffer mechanism of the composite structure was discussed and studied from the view of energy, at the same time, apply high overload impact amplifier loading test technique. The acceleration curve obtained is compared, and the composite structure damping effect is obtained. The structure can satisfy the practical engineering application
