“…Young's modulus of higher filler loading decreased due to the increase of aggregation of NiZn ferrites in PLA/LNR matrix and this can be revealed in SEM analysis later on. The addition of LNR was found to improve the mechanical properties probably due to the existence of rubber particles in the PLA [8]. In Fig.…”

“…In this study, LNR which acts as compatibilizer contributes to the improvement of filler dispersion. The LNR with some active terminals like -OH is expected to react with the plastic particles and thereby bond the plastic particles to the natural rubber matrix [8]. When load is applied, the matrix will distribute the force to NiZn ferrites which carry most of the applied load.…”

Thus, the assistance of LNR is expected not just to improve the bonding between the polymer matrix and NR but also between the PLA and NiZn.…”

Phys. Lett. 93, 242908 (2008); 10.1063/1.3054163Metal-polymer composite with nanostructured filler particles and amplified physical properties Abstract. The mechanical strength of magnetic polymer nanocomposite (MPNC) of nickel zinc (NiZn) ferrite nanoparticles incorporated with polylactic acid (PLA) and liquid natural rubber (LNR) as compatibilizer is reported. The matrix was prepared from PLA and LNR in the ratio of 90:10. The MPNC were prepared at constant mixing temperature at 180ºC, mixing time of 15 min. and mixing speed of 100 rpm. In order to achieve a good dispersion of NiZn ferrite in the matrix, firstly an ultrasonic treatment had been employed to mix the LNR and NiZn ferrite for 1 hour. The MPNC of PLA/LNR/NiZn ferrite then were prepared via Thermo Haake internal mixer using melt-blending method from different filler loading from 1-5 wt% NiZn ferrite. The result of tensile tests showed that as the filler loading increases the tensile strength also increases until an optimum value of filler loading was reached. The Young's modulus, tensile strength and elongation at break have also increased. The study proves that NiZn ferrite is excellent reinforcement filler in PLA matrix. Scanning electron micrograph (SEM) and energy dispersive X-ray spectroscopy (EDX) were meant to show the homogeneity dispersion of nanoparticles within the matrix and to confirm the elemental composition of NiZn ferrites-PLA/LNR nanocomposites respectively.

“…These methods also improved the toughness of natural fiber-UPE composites. The addition of a small amount of liquid natural rubber to kenaf-UPE composites noticeably increased the fracture toughness and impact strength of the composites (Ahmad et al 2010). Haq et al (2008) examined bio-based resins in which a partially-unsaturated polyester and a biobased modifier (epoxified methyl soyate) were used as the matrices to increase the toughness of the resulting nanoclay-hemp-reinforced hybrid bio-based composites.…”

Mechanical and Thermal Properties of Hemp Fiber-Unsaturated Polyester Composites Toughened by Butyl Methacrylate

et al. 2015

Hemp fiber-reinforced unsaturated polyester (UPE) composites were prepared by hand lay-up compression molding. The UPE resins were modified with butyl methacrylate (BMA) to improve the flexibility and toughness of the hemp-UPE composites. The results indicate that the toughness of the composites significantly increased as BMA usage increased. Compared to the unmodified UPE composites, the composites obtained from BMA-modified UPE resins had 27.4, 63.0, and 36.6% greater elongation at break, flexural strain, and impact strength, respectively. The optimum BMA usage to achieve an adequate balance of stiffness and toughness is 20 to 30%. Dynamic mechanical analysis (DMA) indicated that incorporation of BMA significantly decreased the storage modulus and glass transition temperature of the composites and increased its damping parameter due to the introduction of flexible segments into the UPE resins. Thermogravimetric analysis showed that the thermal stability of the composites decreased slightly following the incorporation of BMA. Scanning electron microscopy images of the impact-fractured surfaces of the composites revealed that BMA incorporation improved interfacial adhesion between hemp fibers and UPE matrices and that the main mechanism for the increase in the toughness of the composites was the added ductility of the matrices.

Aging in Water and in an Alkaline Medium of Unsaturated Polyester and Epoxy Resins: Experimental Study and Modeling

et al. 2016

The change in stiffness with temperature in the presence of different media has been discussed for a long time because the ability to predict this behavior becomes fundamental to the design of new materials and their applications. That is why, in this work, the application of a mathematical model, which is able to predict the elastic properties of two polymers, is presented. The study takes into account the relationship between the viscoelastic and absorption properties of these materials in alkaline solution (Ca (OH) 2 , pH 12.5) and in distilled water (H 2 O, pH 7) as the immersion media. Diffusion coefficient values were higher when the resins were immersed in water than in the alkaline solution. In addition, the effect of the alkaline medium was higher for the unsaturated polyester resin (UPR). The highest decrease in modulus at the glassy state of the polymer network was observed for the UPR immersed in the alkaline medium. The greatest reduction of the T g value due to network plasticizing was found for the epoxy resin (ER) in the alkaline medium. Therefore, the ER exhibited a more stable behavior after aging at moderate temperature than the UPR. C 2016 Wiley Periodicals, Inc.
