Maize Stalk As Reinforcement In Natural Rubber Composites
Maize stalk fibres can be used as fillers in natural rubber composites replacing expensive and non-biodegradable inorganic fillers. Maize stalk fibres were chemically modified with acetic anhydride (acetylation) to enhance their compatibility with the hydrophobic rubber polymer matrix. The fibre was characterised using FTIR showing a spectrum with a well defined peak at 1742 cm -1 (attributed t...
متن کاملInfluence of Different Fillers on Natural Rubber Composites to Assess Mechanical Performance
Effect of different fillers on natural rubber compounds was investigated through curing, mechanical properties and morphology studies for improving mechanical performance of rubber articles. In this work, natural rubber blends with Silica as Single-filler compounds, and blends with Silica and Carbon black as Bi-filler compounds were considered. Then, natural rubber blends with Silica, Carbon bl...
متن کاملstudies on properties of short fiber reinforced natural rubber composites
natural rubber/fiber composites were prepared in a laboratory mixer using new and waste short nylon fiber by a one-step mixing process. fiber loading and bonding agent effects on the microstructure and mechanical properties of the composites were studied. the cure characteristics of composites were investigated by using rheometer. cure and scorching times of the composites decreased while maxim...
متن کاملmolecular diffusion of toluene through caco3-filled natural rubber composites
the transport properties of liquids and gases through polymeric materialsplay a very important role in some areas of industrial applications. in thisstudy, natural rubber (nr)/caco3 composites were prepared by melt mixingmethod. by equilibrium swelling test, the transport process of toluene in the prepared natural rubber composites was investigated. the diffusion and transport of toluene throug...
متن کاملDevelopment and Characterization of Polymer Eco-Composites Based on Natural Rubber Reinforced with Natural Fibers
Natural rubber composites filled with short natural fibers (flax and sawdust) were prepared by blending procedure and the elastomer cross-linking was carried out using benzoyl peroxide. The microbial degradation of composites was carried out by incubating with Aspergillus niger recognized for the ability to grow and degrade a broad range of substrates. The extent of biodegradation was evaluated...
