This study presents a novel shock absorber with an inward-inverting composite foam-filled tube. Under the compression of pressing cap and action internal inversion cap, tube inverted inward. During crushing, fronds compacted foam, thereby enhancing energy absorption. Three types foams were applied to absorber, drop-weight impact test was performed obtain assessment parameters. The foam increase...

the importance of the use of activated charcoal tubes for sampling gases and vapors is very well-known. for producing these tubes in the country, their production started in the laboratory of the department of occupation al health using activated charcoal, polyurethane foam and glass wool and consequently two types of foamed and foamless tubes were produced. to investigate the quality of the ra...

Composite metal foams (CMFs) are hybrid structures, which usually produced from separate parts, and not in one step as functional, structural elements. Functional CMFs characterized by high strength, stiffness, extreme energy absorbing properties compared with conventional metallic foams, allow them to be used load-bearing Test specimens made AlMgSi0.5 tubes the wall thickness of 5 mm. AlSi12 c...
