EXPERIMENTAL ANALYSES OF SHOCK PROTECTION AVAILABILITY FOR LOW DENSITY CELLULOSE COMPOSITES

Abstract

The paper presents a set of experimental analyses regarding the behaviour of the low density cellulose composites subjected to the shocking loads. Three types of LDC were considered, and one type of reference polymeric material as expanded polyethylenewas supposed in order to compare the final results. The experimental tests were developed based on laboratory stand for impulsive loads generating, providing the force and the acceleration signals both at the input, and at the output of the probe. The evaluation of availability of these composites to supply shock protective capacity, in order to embed them within such protection devices, fill the goal of this study. The experimental results denote a very good capability to reduce the shock effects, providing some minimal differences depending by the base materials and mixing percentages.
