AB  - Polymer composites based on unsaturated polyester resin (UPR) and reinforced with particles based on unmodified/modified
plant provenance biosilica particles were synthesized and characterized. An unsaturated polyester resin was obtained from
waste poly (ethylene terephthalate (PET). Biosilaca particles are made from rice husk biomass. The surface of the produced
silica particles was modified using three different silanes: 3-trimethoxysilylpropyl methacrylate (MEMO), trimethoxyvinylsilane (TMEVS), and 3-aminopropyltrimethoxysilane (APTMS). The microhardness test method was used to investigate
the mechanical properties of synthesized composite material with variations in dwell times and applied loads. Optimization of
composite microhardness value prediction in function of synthesized parameters (type of modification of silica particles) and
measurement parameters (applied loads and dwell times) was done using the method of response surface methodology (RSM)
regression analysis. The maximal microhardness values (0.459 GPa) were obtained of type modification of silica particles with
vinyl with 80% confidence for 120 experimental variables. This method can be used to choose the optimal dwell time and load
for comparison of measurements between different composite materials and to enable the choice of the material in terms of
optimization of the quality of reinforcement and quality of interphase determined by surface modification.
