In this study, the thermal and mechanical properties of nanocomposite materials were investigated. Produced nanocomposite materials are epoxy-based and reinforced with Multiwalled Carbon Nano Tube dopped polyvinyl alcohol (PVA) nanofibers. Nanofibers were produced by the electrospinning method. Nanofibers were used for reinforcement as 5, 10, and 15 number of layers. These nanocomposite materials were subjected to uniaxial tensile tests at constant tensile speed in accordance with ASTM D882-02 standards. Tensile strength, elasticity modulus, Poisson's ratio, and toughness values were obtained and these values were compared with the values of reference pure epoxy samples without the nanofiber. For obtaining the thermal properties of the samples Thermogravimetric and Differential Thermal Analysis were performed. In order to investigate the damage mechanisms, the fractured tensile test specimens' surfaces were visualized by Scanning Electron Microscopy. Mechanical and thermal properties of the epoxy were improved by using the PVA nanofibers dopped the MWCNT.

This work studied the effects of medium-length fibrous cellulose (MFC) on the morphology, mechanical and thermal properties of poly(lactic acid) (PLA)/propylene-ethylene copolymer (PEC) (90/10) blends. The morphological analysis of PLA/MFC composites observed MFC fibers inserted in the PLA matrix and MFC appeared agglomeration when added high MFC loading. The phase morphology showed the two-phase separation of PLA/PEC blends. The presence of PEC reduced the agglomeration of MFC fibers in polymer matrix. The tensile stress and strain curves found that the ultimate stress of PLA was the highest value and the addition of MFC increased Young’s modulus of PLA/MFC and PLA/PEC/MFC composites. The PEC presence improved the strain at breaking point of PLA/PEC blends. The thermal properties found that the incorporation of MFC did not improve the thermal stability of PLA/MFC and PLA/PEC/MFC composites due to the PLA had degradation temperature higher than MFC.

In this study, a biocomposite consisting of an oil-based network polymer and microfibrillated cellulose (MFC) have been prepared and its mechanical and thermal properties have been evaluated. Epoxidized soybean oil (ESO) was impregnated in a mat of MFC, followed by the acid-catalyzed curing of ESO to produce the biocomposite. SEM observation shows the good dispersion of the cellulose fiber in the oil-based network polymer. The Young's modulus and tensile strength of the biocomposite were much superior to those of the ESO homopolymer and these values increased as a function of the MFC content in the biocomposite. The storage modulus (E’) of the biocomposite in the rubbery region was also larger than that of the ESO homopolymer.
