“…Unsaturated polyester enables to modify performance with low additive profiles [5]. The ideal fraction of filler loading (1-5 wt %) resulting on composite property improvement compared to (10-20 wt %) [6]. The selection properties of filler are important to enhance strength and cost reduction obviously.…”

Abstract. This research is focusing on mechanical and morphological properties of unsaturated polyester (UP) reinforced with two different types of filler which is nano size clay Cloisite 30B (C30B) and Carbon Black (CB). Samples were fabricated via hand lay-up and open molding technique. Percentages of Cloisite 30B & Carbon Black (CB) used vary from 0, 2, 4, 6, 8 and 10 wt%. The mechanical properties were evaluated by impact, flexural and hardness testing. Result shows that the mechanical strength of C30B was better compare to CB filled composite. The combination of UP with C30B helps to improve the properties due to the high surface area of nanosize filler in the matrix. The result shows that increasing of filler content had increased mechanical properties of composites. Optimum percentage represent good mechanical properties are 4% for both fillers. SEM images showed that rough surface image indicate to agglomeration of filler in the matrix for CB sample and smooth surface image on C30B sample indicate to homogenous blending between filler and matrix polyester. SEM images proved that mechanical properties result indicate that C30B polyester composite is a good reinforcement compare to CB polyester composite.

“…Os compósitos derivados de produtos vegetais, tanto na matriz como no reforço, inserem-se na política de aproveitamento de recursos renováveis, menos agressivos e tóxicos, visto que as matérias primas de origem vegetal, tais como: óleos, fibras, polímeros, corantes, etc., além de serem oriun-das de fontes renováveis, atendem aos requisitos de biodegradabilidade e preservação do meio ambiente durante todo o seu ciclo de vida [4,5] . Jayabalan e Lizymol [6] abordaram sobre a importância dos poliuretanos como biomateriais e Melo e Pasa [7] relataram que a presença de ligações éster, grupos hidroxilas e insaturações promovem sítios de reação no óleo de mamona, o que permite o preparo de derivados industriais importantes como o poliuretano.…”

“…Quando a carga além de possuir dimensões nanométri-cas, interage com a matriz em escala nanométrica, têm-se os nanocompósitos poliméricos que constituem uma nova classe de materiais de grande interesse acadêmico e industrial por apresentarem, em baixos níveis de carregamento, um aumento excepcional em suas propriedades mecânicas, térmicas e de barreira, se comparados aos compósitos convencionais [4][5] . A grande maioria dos nanocompósitos poliméricos produzidos atualmente tem argilas bentoníticas como elemento de reforço.…”

Resumo: Neste trabalho as propriedades mecânicas de um compósito, formado a partir de uma matriz de poliuretano derivado do óleo de mamona e reforçada por um tecido tramado de juta, foram avaliadas. O efeito da adição de pequenos teores de bentonita cálcica e sódica sobre as propriedades mecânicas da matriz de poliuretano e de compósitos poliuretano/juta também foi investigado. Os resultados indicam que a incorporação de fibra de juta à matriz poliuretana promoveu melhora significativa nas propriedades sob tração dos compósitos. A adição de pequenos teores de argila à matriz alterou o desempenho mecânico dos compósitos, porém os resultados não foram os esperados. O compósito híbrido poliuretano/argila/fibra de juta, contudo, apresentou propriedades mecânicas superiores às dos compósitos reforçados unicamente com tecido de juta, o que indica uma atuação sinérgica dos reforços híbridos argila/juta. Palavras-chave:Compósito, poliuretano, fibra de juta, carga nanoparticulada. Influence of a Nanoparticulate Filler Addition on the Mechanical Properties of Polyurethane/Jute Fiber CompositesAbstract: In this work the mechanical properties of polyurethane/jute fiber composites were evaluated as a function of fiber content and mineral filler addition. A polyurethane (PU) derived from castor oil was used as the matrix and hessian cloth as reinforcement. The effect of the incorporation of small amounts of local clay (bentonite), in its calcium and sodium forms, on the mechanical properties of polyurethane/jute composites was also investigated. The results indicate that the tensile properties of the composites substantially increased with jute fiber addition and that although the mechanical properties of the matrix were affected by the addition of nanoparticulate clay, the improvement was not as expected. This was attributed to poor mixing and dispersion of the filler, which was confirmed by SEM. A synergistic effect was observed for the hybrid clay/jute fiber composites, with considerable improvement in the mechanical performance of the hybrid composites.

ABSTRACT:The synthesis and properties of the organic polymersilica nanocomposites by blending perhydropolysilazane with organic polymer having hydroxyl groups have been described. Poly(methyl methacrylate) (PMMA)-silica nanocomposites with a PMMA/silica lamellar structure and spherical silica domains in a PMMA matrix were obtained with random copolymers and block copolymers. The effect of the architecture of the random and block copolymers on the morphology of composites has been summarized. The thermal stability, electrical properties, such as field break down, leakage current, etc., and surface hardness of the composites have been discussed.
