Abstract:
In order to decrease the damage on the knee of the elderly due to falling down, warp knitted spaced fabric was fabricated, and the experiment on static anti-compression performance of polyurethane foam was carried out with the Instron tester. This paper aims to study the knee protective system for the elderly, using the Instron tester AGS-J from Tianjin Polytechnic University to study the static compression performance. This conclusion can be found: for PU sponge, spacer fabric, a certain density of PU and some special structures of spacer fabrics can meet the requirement of the energy release during the fall. Especially, for the spacer fabric, when the internal pressure is above 30Kpa, the buffer coefficient comes to the minimum, and the anti-compression performance of spacer fabric comes to the best.
Key words: knee protector, polyurethane material, spacer fabric, anti-compression performance, compression energy absorption
