Studies of glued bamboo-wood composite for strength characteristics in the manufacture of aviation structural elements

Abstract

The goal of this study was the intention to demonstrate the expediency of utilization of bamboo composites in manufacturing of aircrafts. The research and testing of the material were conducted in the laboratories of the Institute of Aerospace Technolgies (IAT) of the National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute”. To determine the expediency of using bamboo composite, it is necessary to conduct tests of the material for external effects and analyse economic feasibility. The main advantages of such a material are its environmental friendliness and cheapness of both raw materials and processing. This article is dedicated to analysing the results of the research on the mechanical characteristics and economic aspects. Bars of different sizes, different materials, and different degrees of processing were used for the analysis. The results of the testing conducted have showed that the strength characteristics of a bamboo composite are higher than that of the majority of wood species. At the same time, bamboo elements are lighter judging by weight characteristics. The undisputable advantage of their usage is a powerful and widespread structure of existing manufacturing which does not require creation of new processing machinery.
