Thermoplastic polyurethane elastomer (TPU) and long glass fiber (LGF) were used to prepare LGF/TPU master batch for increasing the mechanical properties and heat resistance of PVC. It turned out that addition of LGF/TPU contributed to improvement in toughness of PVC but the heat resistance of PVC didn’t increase very evidently. The heat resistance and morphology were observed by vicat test and scanning electron microscopy, respectively. The scanning electron microscopy (SEM) proved that incorporation of LGF/TPU into PVC changed the morphology of the composites and correlated well with the mechanical properties. Dynamic mechanical analysis (DMA) showed that both the glass transition temperature and the storage modulus of PVC increased with the addition of LGF/TPU master batch; the presence of a single Tg indicated that each component of composites was miscible. In this study, the combination properties of the composites with 24wt% LGF was the best proportion in the range of 0-30 phr LGF, because it had the best mechanical properties and heat resistance.

The influence of long glass fiber (LGF) content on properties of PVC/PP composites were investigated by means of scanning electron microscopy (SEM), dynamic mechanical analysis (DMA), and mechanical properties. The experimental results demonstrate that long glass fiber could effectively improve the mechanical properties and storage modulus of PVC/PP. The DMA reveals good miscibility between PVC and PP. Based on SEM, good interfacial adhesion between matrix and long glass fiber in PVC/PP/LGF composites was observed. All results in this paper were consistent, and showed long glass fiber could effective influence the properties of PVC/PP, which were proved by the mechanical properties of the composites.

The effects of polypropylene grafted with maleic anhydride (PP-g-MA) on the interfacial interaction of PP/GF composites were investigated by means of scanning electron microscopy (SEM), dynamic mechanical analysis (DMA), and mechanical properties. The experimental results demonstrate that PP-g-MA could effectively improve interfacial interaction between the PP and LGF. Based on SEM, good interfacial adhesion between PP and LGF in PP/PP-g-MA/LGF（66.5/3.5/30） composites was observed. All results in this paper were consistent, and showed the good interaction between PP and LGF, which were proved by the mechanical properties of the composites.

AbstractA series of long glass fiber (LGF)-reinforced epoxy resin (ER), thermoplastic polyurethane (TPU) elastomers, and poly(methyl methacrylate) (PMMA) composites were prepared by using self-designed impregnation device. Dynamic mechanical properties of the LGF/ER/TPU/PMMA composites have been investigated by using dynamic mechanical thermal analysis (DMA). The results indicated that the content of PMMA and TPU and scanning frequency had important influence on dynamic mechanical properties and glass transition of the LGF/ER/TPU/PMMA composites. In addition, the Arrhenius relationship has been used to calculate the activation energy of α-transition of the LGF/ER/TPU/PMMA composites. The thermal properties of the LGF/ER/TPU/PMMA composites were studied by thermogravimetric analysis (TGA). Morphology and mechanical properties of the composites are investigated by scanning electron microscopy (SEM), a universal testing machine, and a ZBC-4 Impact Pendulum.

AbstractA series of long glass fiber-reinforced thermoplastic polyurethane (TPU) elastomers and acrylonitrile-butadiene-styrene (ABS) copolymer (LGF/TPU/ABS) composites were prepared using self-designed impregnation device. Poly(styrene-co-maleic anhydride) was employed to increase the compatibility between glass fiber and matrix resin and thus obtain the excellent properties of composites. The dynamic mechanical properties of the composites have been investigated using dynamic mechanical thermal analysis. The results indicated that the storage modulus of the composites gradually increases and then decreases with increasing compatibilizer content. In addition, the low temperature peak of the composites shifts to higher temperature with increasing compatibilizer content. The thermal properties of the composites were studied by thermogravimetric analyzer. In addition, the morphology and mechanical properties of the composites are investigated by scanning electron microscopy, a universal testing machine, and a ZBC-4 Impact Pendulum.

Better Than

The aromatic polyamides form a class of fibers having mechanical properties which are much better than those of aliphatic polyamides. Currently, the accepted morphology of these fibers as proposed by M.G. Dobb, et al. is a radial arrangement of pleated sheets, with the plane of the pleats parallel to the axis of the fiber. We have recently obtained evidence which supports a different morphology of this type of fiber, using ultramicrotomy and ion-thinning techniques to prepare specimens for transmission and scanning electron microscopy.

Polylactic acid (PLA) is one of the most suitable materials for 3D printing. Blending with nanoparticles improves some of its properties, broadening its application possibilities. The article presents a study of composite PLA matrix filaments with added unmodified and lignin/polymerised lignin surface-modified nanofibrillated cellulose (NFC). The influence of untreated and surface-modified NFC on morphological, mechanical, technological, infrared spectroscopic, and dynamic mechanical properties was evaluated for different groups of samples. As determined by the stereo and scanning electron microscopy, the unmodified and surface-modified NFCs with lignin and polymerised lignin were present in the form of plate-shaped agglomerates. The addition of NFC slightly reduced the filaments’ tensile strength, stretchability, and ability to absorb energy, while in contrast, the initial modulus slightly improved. By adding NFC to the PLA matrix, the bending storage modulus (E’) decreased slightly at lower temperatures, especially in the PLA samples with 3 wt% and 5 wt% NFC. When NFC was modified with lignin and polymerised lignin, an increase in E’ was noticed, especially in the glassy state.

In this work, a mechanically durable anticorrosion superhydrophobic coating is developed using a nanocomposite coating solution composed of silica nanoparticles and epoxy resin. The nanocomposite coating developed was tested for its superhydrophobic behavior using goniometry; surface morphology using scanning electron microscopy and atomic force microscopy; elemental composition using energy dispersive X-ray spectroscopy; corrosion resistance using atomic force microscopy; and potentiodynamic polarization measurements. The nanocomposite coating possesses hierarchical micro/nanostructures, according to the scanning electron microscopy images, and the presence of such structures was further confirmed by the atomic force microscopy images. The developed nanocomposite coating was found to be highly superhydrophobic as well as corrosion resistant, according to the results from static contact angle measurement and potentiodynamic polarization measurement, respectively. The abrasion resistance and mechanical durability of the nanocomposite coating were studied by abrasion tests, and the mechanical properties such as reduced modulus and Berkovich hardness were evaluated with the aid of nanoindentation tests.
