Analysis of mechanical properties of 3D-printing honeycomb in temporary construction

Abstract:

To study and improve the traditional temporary buildings, such as wood, paper tube, bamboo, simple tents and other materials made of temporary shelters. There are some problems of temporary shelters such as weak designability, thick materials, insufficient mechanical properties and so on. In this paper, chiral honeycomb, hexagonal honeycomb, concave hexagonal honeycomb, star honeycomb and triangular honeycomb structures were fabricated by 3D printing technology. In-plane tension, out-of-plane bending and in-plane compression characteristics were tested. The results show that the chiral honeycomb structure has a large bearing capacity, and the comprehensive mechanical properties of the hexagonal honeycomb structure are better than the other four structures. This study shows that the honeycomb structure designed in this paper is superior to the traditional temporary building materials. Under certain conditions, the chiral honeycomb and hexagonal honeycomb structure prepared by using PLA material can meet the the needs of mechanical properties and design of temporary buildings after disaster, save manpower with light materials, and effectively reduce the secondary damage of temporary buildings to victims.
