Created mikrostrukturirovannyy material romwell with unusual properties | Required romwell Information for Everyone
German scientists have developed a lightweight and high-strength material that is usually prompted by nature. The basis was taken framing bone and wood, and a honeycomb structure obolochechnaya. Material generated by laser printing three-dimensional polymer filament with a ceramic coating has a density less than that of water of the same size and strength comparable to the strength of stainless steel or aluminum. romwell
Polymer Microarchitecture, created by a team of researchers from the Karlsruhe Institute of Technology (Karlsruher Institut f? R Technologie, KIT), is superior to their natural counterparts relative romwell strength to density. The supporting structure was made ?? using 3D laser lithography technology or polymer printing romwell zatverdenyem wrote GizMag.

Scientists have tried several different agencies, including triangular, hexagonal and yacheystuyu (cellular) structure. To give added strength they gave coating that besieged the gas phase. romwell As the coating was tested ceramic material and aluminum. Dimensions polymer structure amounted romwell to approximately 50 microns in length, width and height, and coating thickness romwell - from 10 to 200 nanometers (vyprobuvalosya many options).
The study found that the polymer structure with symmetrically arranged hexagonal cells with aluminum coating thickness of 50 nm has an extremely high ratio of tensile strength to density. Thus, this Microarchitecture surpassed their triangular romwell and hexagonal competitors. Although optimized cellular structure could not stand the pressure of 28 kg / mm2, its density in the tests was 810 kg / m3, which, according to scientists, the higher the ratio of strength to bone density, romwell steel and aluminum.
New lightweight construction materials reminiscent framing half-timbered houses with horizontal, vertical and diagonal struts. Only in this case the beam size with only 10 microns - said study co-author Jens Bauer.
Researchers say that mikrostrukturirovannye materials commonly used for insulation or depreciation. Materials romwell with open pores can also serve as filters for the chemical industry.
