They form a strength-giving protective layer around the woody central portion of the stem, and are themselves protected by an outermost cuticle which contains waxes and other substances. Examples of bast fibres in-clude hemp, jute, flax, ramie, and kenaf. Roselle fibre is a fine bast fibre. Bast fibres have many textile applications, with natural fibre composites being the fastest growing due to the combination of their relatively low cost and excellent technical characteristics. The mechanical properties such as tensile, compressive, flexural, impact strength and water absorption of the alkali treated continuous Agave fibre reinforced epoxy composite (TCEC) and untreated continuous Agave fibre reinforced epoxy composite (UTCEC) were analysed. However, there is still lack of knowledge on selecting the best properties of two main components; bast and core fibre. Elongation: 1.7% at the break. Morphological Properties.

People also read lists articles that other readers of this article have read. The mechanical properties of wheat fibre bundles are inferior to the properties of conventional textile bast fibres. The main purpose of this research is to exploit new bio-fibre resources for the structural composite industries. These properties are highly variable, depending on both the chemical composition of the fibre and the environmental conditions. The fibres occur in bundles or aggregates [Hearle 1963]. Fibers with the high-est aspect ratio will exhibit highest tensile properties provide high surface area which are advantageous for reinforcement purposes. The physical and mechanical properties of these fibres are still being explored. Bast and Leaf fibers. During harvesting, the plant stalks are cut off close to the base or pulled up. Physical properties of natural fibres depend on several factors (Rowell et al. Important characteristics of these plant fibres include physical, mechanical, dielectric, degradation, hygroscopic, and surface properties. They have similar properties to the afore mentioned fibres. The increase in total fibre production is mainly due to growth in population whereas the trend from naturally occurring fibres to man-made fibres reflects many factors inc1uding their desirable physical properties, uniformity, stability of supply and in many cases comparatively low price tag. Homogenous fibre cement boards were made from kenaf bast fibres, cement and water. Hemp fibres are finding increasing use as reinforcements in composite materials, often replacing glass fibres. Structural composite is a material made from two or more constituent materials with significantly different physical or chemical properties. Bast fibres have many textile applications, with natural fibre composites being the fastest growing due to the combination of their relatively low cost and excellent technical characteristics.

Hemp fibers are one of the strongest and most durable among all of the natural textile fibers. Bast [and leaf quality fibres are the most commonly used in composite applications [3]. In contrast, mechanical extraction is faster and more environmentally friendly but results in low-purity fibre. The molecules are oriented and arranged parallel along the major axis of the fibre to yield Bast (băst), ancient Egyptian cat goddess. This study investigated the effect of pretreatment on the properties of kenaf fibre cement boards. Followings are the physical properties of silk: Color: The color of silk fiber could be yellow, brown, green or grey.

The effect of using different mercerization media on some mechanical properties of local plant bast fibres, Roselle (Hibiscus sabdariffa), kenaf (Hibiscus cannabinus), okra (Hibiscus esculentus), Baobab (Adansonia digitata) respectively, were generally investigated. The morphology of the natural fibre is one of the factors that influences the physical and mechanical properties of the fibre as a reinforcement material for composites material (Munawar et al. Such fibres, usually characterized by fineness and flexibility, are also known as “soft” fibres, distinguishing them from the coarser, less flexible fibres of the leaf, or “hard,” fibre group. One of these properties is the thermal degradation at elevated temperatures. The molecules are oriented and arranged parallel along the major axis of the fibre to yield high strength and anisotropy.
