Optimization of the Tensile Properties of Polymeric Matrix Composites Reinforced with Magnetite Particles by Experimental Design

Abstract

A full-factorial 33 experiment was used in this study to determine the optimal values of the tensile properties of three composite materials manufactured based on three polymeric resins: Derakane Momentum epoxy vinyl ester based on bisphenol-A (DM-411), polyester based on terephthalic acid (P115-A), and isophthalic polyester (P2000). Such materials were reinforced with magnetite powders at concentrations of 10, 20, and 30 wt %, and the particle sizes were classified with three sieves: #200 (46–75 μm), #325 (26–45 μm), and #500 (0–25 μm). The compounds were manufactured using the hand lay-up method at room temperature in accordance with ASTM D638-14 for M1-type specimens. A tensile test was conducted on a universal Microtest EM2/300/FR machine at a test speed of 5 ± 25 % mm/min using an Epsilon extensometer calibrated in accordance with the ASTM E83 standard at 20 ± 2 °C. The magnetite powders and compound morphology were studied by Scanning Electron Microscopy. The mechanical properties of the compounds and the optimal response found by Analysis of Variance (ANOVA) and Response Surface Methodology (RSM) are also reported. The best response to the mechanical stimuli occurs with the composite material prepared with the epoxy vinyl ester resin DM-411, a concentration of 29.4 % of magnetite (Fe3O4), a particle size of 58.5 microns, and a 200 sieve.

Development and verification of mechanical characteristics of a composite material made of a thermoplastic matrix and short glass fibers

“…Based on the literature data [12][13][14][15] devoted to the study of dispersed-filled composites based on thermoplastic polymers, it can be concluded that their properties are determined by the content and shape of particles. One of the significant factors affecting the mechanical properties of the composite is the orientation of fibers in space.…”

“…In [13], the mechanical properties of composite materials made of three different types of polymer resins (namely, DM411 epoxy-vinyl ether, poly-pyrizophthalic P2000 and poly-terephthalic P115A) were studied. Such materials contained different concentrations of magnetite (Fe 3 O 4 ) in the functional fillers and had different particle sizes.…”

Fabrication and Analysis of the HLM Method of Layered Polymer Bumper with the Fracture Surface Micrographs

“…In this study, Kenaf (KE) and palm empty fruit bunch bre (EFB) with volume fractions of Vf of 20%, 40%, and 60% were used in this study to prepare composites that comprised polylactic acid (PLA), polystyrene (PS), and epoxy (EP) as the matrices. e tensile strength was attained at a minimum of 29 MPa due to the percentage of bre addition up to 20% according to the discussion of [15] Lara-González et al e tensile strength was found to be nearly 22.88 MPa, with a maximum of 56.47 MPa. Comparatively, the basalt bre and aluminium combined bre composite has attained a 38 MPa as minimum.…”

“…Because of the high proportion of fibre, the tensile strength was at least 29 MPa. According to Luis Angel Lara-González et al's discussion in [15], the tensile strength was around 22.88 MPa and reached a high of 56.47 MPa. e mixed fibre composite made of basalt and aluminium has a minimum strength of 38 MPa.…”
