Mechanical behaviour of biophotocomposite materials: An experimentally validated micromechanics model for tensile strength

The aim of this study is to compare tensile strength by experimentally and micromechanically model mathematic. The tensile strength of materials can be predicted by both tensile strengths of matrix and reinforcement constituent. These biocomposite materials consist of hydroxyapatite (HA) as a filler, Tri[ethylene glycol] dimethacrilate (TEGDMA (Sigma-Aldrich)) monomer as a matrix, glass fibers as a reinforcement, shellac as a coupling agent and camphorquinone (Sigma Aldrich) as a photoinitiator. The elements of a composites constituents have known Rule of Mixtures. The result of this study shows that the tensile strength of a composite can be predicted by calculating the tensile strength of its constituent materials. The values of the prediction tensile strength were between of HA’s tensile strength; glass fibres tensile strength and matrix’s tensile strength. The tensile strength of the materials was significantly influenced by adding the glass fibre.
