Abstract
Importance and use of composite materials are no longer a subject that should be emphasized. They offer a successful replacement for classical materials in most areas of engineering, conferring similar elastic-mechanical properties to metal or non-metal alloys with several advantages such as reduced mass, chemical resistance etc. Considering this, knowledge of the elastic-mechanical characteristics is of utmost importance. The present article aims to create a finite element model that can predict the longitudinal elastic modulus of a double-layered composite material based on the elastic characteristics of its constituents. For this, the elastic characteristics of the constituents were determined, then used in the finite element analysis thus obtaining the Young�s modulus for the numerical composite material. Also, the longitudinal elastic modulus of the resultant composite was determined experimentally. The results of the finite element model were compared with experimental values.
Highlights
Importance and use of composite materials are no longer a subject that should be emphasized
In recent years, detailed analyses and experiments regarding the behavioural pattern of composite materials took a turn for faster and cheaper mechanical characterization
A prediction of the effective elastic properties and the meso-scale mechanical response been presented to verify the validation of the finite element modelling (FEM)
Summary
Importance and use of composite materials are no longer a subject that should be emphasized. A numerical approach, such as finite element modelling (FEM), offers faster, cheaper and more detailed results for an infinite number of composite materials configurations. Considering all of the above, the authors could establish a proper protocol for creating a 3D model and obtaining the Young’s modulus for a fibreglass reinforced polymer composite material.
