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.

Morphology And Mechanical Properties

The effects of polypropylene grafted with maleic anhydride (PP-g-MA) and epoxy resin (ER) on the interfacial interaction of the long glass fiber reinforced PP composites were investigated by means of scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and mechanical properties. The experimental results demonstrate that PP-g-MA and ER 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/ER/LGF composite was observed. DSC results showed that the existense of PP-g-MA or ER caused crystallization temperature shift to low temperature, and melting temperature shift to high temperature. 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.

This paper deals with the synthesis of polyurea and its use as polymer matrix for nanocomposites reinforced with multi-walled carbon nanotubes (MWCNT). Two types of materials were obtained during this research, the first cathegory uses the polyurea as matrix and the second one uses a mixture between epoxy resin and polyurea. The nanocomposites were characterized by Thermogravimetric Analysis (TGA), Dynamic Mechanical Analysis (DMA), Scanning Electron Microscopy (SEM) and Tensile Tests .The elastomeric features of nanocomposites were highlighted by the results which showed low value of Tg. Also higher thermal stability with ~40oC compared with commercial products (M20) were observed, but lower mechanical properties compared to neat polyurea.

A polyurethane/clay (PU/clay) composite was synthesized. The microstructure of the composite was examined by scanning electron microscopy. The impact properties of the composite were characterized by impact testing. The study on the structure of the composite showed that clays could be dispersed in the polymer matrix well apart from a few of clusters. The results from mechanical analysis indicated that the impact properties of the composite were increased greatly in comparison with pure polyurethane. The investigation on the mechanical properties showed that the impact strength could be obviously increased by adding 20 wt% (by weight) clay to the matrix.

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.

This paper presents a study on the effect of alkali treatment of Oil Palm Kernel Shell (OPKS) on the mechanical properties ofpolyester composite. The dosage of NaOH in this study is limited to 5wt% concentration.The experiments on mechanical properties investigate the tensile strength, the flexural strength and theflextural modulus of untreated, cold alkali treated and hot alkali treated OPKS reinforced polyester composite. It is found that the alkali treatment improves the mechanical properties of the composite. However, the improvement due tothe hot alkali treatment is significant compared to the cold alkali treatment. The morphology of OPKS and the fracture surface of OPKS composites were investigated using scanning electron microscopy (SEM), showing a rough surface and good interfacial adhesion between OPKS as filler and polyester as a matrix.

AbstractThe mechanical properties of polybenzoxazine (PBa) resins were improved by adding polyamide 12 (PA12) and modified montmorillonite (OMMT) as additives. The mechanical properties and thermal stability of PBa and resulting PBa composites were investigated using an Instron universal material testing instrument and dynamic mechanical analysis. The morphologies of the fracture surfaces were characterized by scanning electron microscopy. The results of morphological studies showed that PBa/PA12/OMMT composites exhibit significantly improved mechanical properties and thermal stability compared with that of the pristine PBa. When the OMMT content increased to 1 wt%, the fracture toughness (1.36 MPa·m1/2) and the fracture energy (GIC, 315.76 J·m−2) of PBa/PA12/OMMT-1 composites increased by 67.9% and 181.4%, respectively, compared with those of the pristine PBa. The thermal stability properties demonstrated that the storage modulus and glass transition temperature (Tg) of PBa/PA12/OMMT composites gradually increased with the addition of OMMT particles. The scanning electron microscopy results indicated that PBa/PA12/OMMT composites possess a toughening mechanism of crack deflection, with a large bulk of voids and debonding induced by PA12 and OMMT clay particles. Moreover, the OMMT might provide microvoid nucleating sites at its surface to release constrains for shear yielding.

In this research, the Thermoplastic Starch (TPS) is blended with Polylactic Acid (PLA). By treating TPS with CA, the interfacial adhesion of PLA/TPS blend was also being improved. The ratio between PLA/TPS was chosen at 60/40 and 40/60 and CA contents were varied from 0%, 3%, and 6%. After acidolysis of TPS by CA, the tensile strength (60/40) and (40/60) of the PLA/TPS blend were found to increase. However, the elongation at break of PLA/TPS (60/40) blend was lower compared to PLA/TPS (40/60) blend. Higher loadings of TPS in the blend tend to make the blend elongate due to the flexibility of TPS after CA modification. On the other hand, by modifying the TPS with CA, the surface tension at the PLS/TPS interface had been reduced. This can be seen through micrograph that obtained from scanning electron microscopy. Different CA content in PLA/TPS blend showed the dispersed or co-continuous structure, which were related with the mechanical properties.

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.
