Procedures in testing the mechanical characteristics of composite structures and the possibility of application to biodegradable materials: An overview

Abstract

This paper presents the static testing of the composite material's mechanical characteristics. An overview of the standards is made by which various tests are performed, and then an analysis of the results of the parameters obtained by the conventional method-stretching and optical (DIC system-bending) of carbon epoxy composite structures is given. These results represented the basis for the preparation and further application of biocomposite materials; that is, the testing procedure will be performed identically on composites containing mycelia. The mould for pressing biomaterial connected with mycelium is made of two parts. The primary purpose of the mould is to bring the loose natural material into a solid preparation following the standards ASTM D3039 and ASTM D7078, which include testing the technologically prepared and hardened sample for bending and shearing.
