The effects of styrene-maleic anhydride copolymer (SMA) and epoxy resin (ER) on the interfacial interaction of Acrylonitrile-butadiene-styrene terpolymer/Short glass fiber composites were investigated by means of scanning electron microscopy (SEM), dynamic mechanical analysis (DMA), and mechanical properties. The experimental results demonstrate that SMA and ER could effectively improve interfacial interaction between the ABS and SGF. Based on SEM, good interfacial adhesion between ABS and SGF in ABS/SMA/ER/SGF and ABS/ER/SGF composites was observed. DMA results showed that SMA and ER decreased the glass transition temperature (Tg) and height of tanδ compared with ABS/SGF composites. The synergy effects of SMA and ER on the interface interaction was investigated. All results in this paper were consistent, and showed a good interaction between ABS and SGF, which was proven by the mechanical properties of the composites.

AbstractThe short glass fiber (SGF)/polypropylene (PP) and ethylene-1-octene copolymer (POE)/SGF/PP foam composites were prepared by extrusion and subsequent post-foaming process in designed dies. The compatilizers, maleic anhydride grafted PP (PP-g-MAH) and maleic anhydride grafted POE (POE-g- MAH), were employed to improve the performance of the foam composites, respectively, and their influences on the cellular structures, interfacial morphologies and mechanical properties of PP foam composites were investigated. It was found that the compatilizers resulted in modified PP foam composites characterized by uniform cell size distribution, reduced cell size and increased cell density except POE/SGF/PP with POE-g-MAH. The obvious enhanced SGF-matrix interfacial bonding was observed from the SEM examination, and POE-g-MAH also facilitated the compatibility between elastomeric particles and matrix. Testing results indicated that, by the introduction of PP-g-MAH or POE-g-MAH, the mechanical properties of PP foam composites were significantly improved, and it seemed that the PP-g-MAH was more effective in strengthening the flexural and compressive strength while POE-g-MAH greatly increased the impact toughness.

<p class="1Body">Short glass fibre reinforcement is one of the most important measures to improve the mechanical properties of injection moulded parts. The need for increasing performance leads to high fibre contents which is a critical fact due to the contrasting behaviour of strength, stiffness and impact properties. In this study a high-fluidity polypropylene (PP) is compounded with short glass fibres up to 70 weight percent and comparatively investigated with the adding of maleic anhydride (MAH) as compatibilizer. Due to the high fluidity of the PP, which ensures a good embedding of the fibres, the tensile modulus increases up to 65 weight percent, tensile strength up to 50 weight percent of glass fibre content. Adding the MAH increases strength and impact properties, while the tensile modulus only shows an improvement at high fibre content. The influence of the compatibilizer effect diminishes at higher fibre contents, especially for the impact strength which could so far not be clarified exactly. Reasons could be the reduction of fibre length at higher fibre contents and the increasing influence of the brittle fibre component. With the adding of MAH the contrasting behaviour of the impact properties in comparison to strength and stiffness can be reduced and the optimum over all mechanical properties can be shifted to higher fibre contents.</p>

Styrene Maleic Anhydride

A commercial grade of polypropylene matrix reinforced with waste polyamide (nylon 6) fibres of two diameters at levels up to 40wt% (100 polypropylene + 40 polyamide) was studied. Smaller diameter fibres showed better mechanical properties than larger diameter ones. Attempts were made to improve the interfacial adhesion between the fibres and the matrix by grafting with maleic anhydride and with also styrene maleic anhydride. The mechanical properties showed significant improvements as a result of these modifications. Thermal stability was also marginally improved. These composites could be easily recycled by processing them above the melting point of the reinforcing fibres.
