Prototipo de hueso humano y propiedades mecánicas de un biomaterial a partir de ramas de guadua

Abstract

The main objective of this paper is to describe the development of a prototype of human bone (cortical rib), tacuaras from bamboo; plant genus representative of Andean forests of Latin American and Asian countries, and the evaluation of the mechanical properties of this material for the development of a biomaterial. The treatment of the raw material for prototype development and mechanical characterizations from tensile, compression and hardness are shown here. This work shows the static mechanical properties of a biomaterial created from bamboo branches and cobalted resin, their response to different loads and their possible use for the design of prostheses. The results show that the material under test can be classified as linear elastic material, with a hardness of 17.2HV, which compared with an actual bone hardness is considered as a medium hardness and with a deformation similar to bone dry real 2.75 ± 0.72%. Additionally, the material shown a maximum tensile stress of 11.98 ± 2.57MPa, which is between the range of 8-50MPa, corresponding to real trabecular bone.
