TL;DR: In this article , a characterization of thermal, mechanical and microstructural properties of alkali treated jute fiber polymer composites with special emphasis on fiber length is presented, where composite samples are fabricated via compression molding technique by a constant weight proportion of 60 ¼wt% isopthalic polyester (IP) and 40 ¼ wt% chopped alkali-treated jute fibre (ATJF) of various lengths.
Abstract: Nowadays, researchers are striving forward to find an alternative sustainable material for harmful man-made fibers. In line with this, natural fibers are more recommended as sustainable reinforcements because of their specific properties suited for diverse applications. The present work deals with the inclusive characterization of thermal, mechanical and microstructural properties of alkali treated jute fiber polymer composites with special emphasis on fiber length. Composite samples are fabricated via compression molding technique by a constant weight proportion of 60 ​wt% isopthalic polyester (IP) and 40 ​wt% chopped alkali treated jute fiber (ATJF) of various lengths (5 ​mm, 10 ​mm, 15 ​mm, 20 ​mm and 25 ​mm). The mechanical performance of fabricated composites is assessed by doing tensile, impact and flexural tests and found better composite properties for 20 ​mm fiber length. Also, the thermogravimetric analysis (TGA) as well as Differential thermogravimetric analysis (DTA) confirmed better thermal stability (approx. 280 ​°C) for the fabricated composite. In addition, the Fourier Transformation Infrared Spectroscopy (FTIR), X-ray diffraction (XRD) technique and Scanning Electron Microscope (SEM) describes the functional groups, estimated average grain size 13.0789675 ​Å and morphological features of developed composites respectively. As a result, the above assessment promotes a better impact to polymer industries by employing the fabricated sustainable composites in divergent lightweight and high strength applications.

Abstract: In this review paper, the use of different parts of tamarind tree in industry for eco-friendly products and processes with sustainability has been explored. This review article presents the extraction methods adapted to modify the raw materials obtained from tamarind tree into useable form by industry. The review of published data reveals that, fruit shell can be efficiently used as toxic adsorbent, pulp is used in food industry as preservative, Tamarind seed polysaccharide (TSP) a biopolymer from tamarind seed is effectively used as additive in food industry, drug delivery applications and electrochemical industries. The tamarind seed oil is used as biofuel, tamarind leaf extract is employed in textile industry for developing antibacterial fabrics and fruit fiber is successfully used as reinforcement in composite material to replace synthetic fibers and finds application in automobile and construction industries. This study also exposes the fact that there is scope for further use of tamarind and its parts in several areas such targeted drug delivery applications, removal of toxins from industrial effluents, electrochemical industries, agricultural field and preparation of preserved foods which require further research.

TL;DR: In this article, the authors evaluated the mechanical properties of woven jute fabric-reinforced composites using hand lay-up techniques as per the ASTM standard, including tensile strength, compressive strength, flexural strength, impact strength, inplane shear strength, interlaminar shear and hardness.
Abstract: This research work is concerned with the evaluation of the mechanical properties—modulus, Poisson's ratio and strength—of woven jute fabric-reinforced composites. The specimens are prepared using hand lay-up techniques as per the ASTM standard. This is the first report by any single group of researchers in which tensile strength, compressive strength, flexural strength, impact strength, inplane shear strength, interlaminar shear strength and hardness are given. This work being an experimental study on untreated (`as received' jute fabric) woven jute fabric-reinforced polyester composites, demonstrates the potential of this renewable source of natural fibre for use in a number of consumable goods.

TL;DR: In this article, chemical modifications were made to sisal fiber using a urethane derivative of polypropylene glycol (PPG/TDI), maleic anhydride modified polypropylon (MAPP), and KMnO4 in order to improve the interfacial adhesion between the fibre and matrix.
Abstract: The thermal and crystallisation behaviour of sisal/PP composites was studied by thermogravimetry (TG), differential scanning calorimetry (DSC) and polarising optical microscopy. Chemical modifications were made to sisal fibre using a urethane derivative of polypropylene glycol (PPG/TDI), maleic anhydride modified polypropylene (MAPP), and KMnO4 in order to improve the interfacial adhesion between the fibre and matrix. The thermal properties of the blends were analysed by TG analysis. The effects of fibre content and chemical treatments on the thermal properties were evaluated. It was found that treated fibre composites show superior properties compared to the untreated system. DSC measurements exhibited an increase in the crystallisation temperature and crystallinity, upon the addition of fibres to the PP matrix. This is attributed to the nucleating effects of the fibre surfaces, resulting in the formation of transcrystalline regions. On increasing the fibre content, the melting peak of the PP component was shifted to higher temperatures suggesting a constrained melting. The thickness of the transcrystalline layer formed depends on crystallisation temperature and time. The transcrystalline growth rate was slow in the quiescent state. On the other hand, upon the application of stress, transcrystallinity developed quickly. In fact, the shear stress at the polymer/fibre interface initiated the nucleation. Fibre surface modification by PPG/TDI increases the nucleating ability of sisal fibre to a very small extent.

TL;DR: In this paper, the tensile, flexural, and impact behavior of Pineapple leaf fiber-reinforced polyes- ter composites as a function of fiber loading, fiber length, and fiber surface modification was investigated.
Abstract: Pineapple leaf fiber (PALF) which is rich in cellulose, relatively inexpen- sive, and abundantly available has the potential for polymer reinforcement. The present study investigated the tensile, flexural, and impact behavior of PALF-reinforced polyes- ter composites as a function of fiber loading, fiber length, and fiber surface modification. The tensile strength and Young's modulus of the composites were found to increase with fiber content in accordance with the rule of mixtures. The elongation at break of the composites exhibits an increase by the introduction of fiber. The mechanical proper- ties are optimum at a fiber length of 30 mm. The flexural stiffness and flexural strength of the composites with a 30% fiber weight fraction are 2.76 GPa and 80.2 MPa, respec- tively. The specific flexural stiffness of the composite is about 2.3 times greater than that of neat polyester resin. The work of fracture (impact strength) of the composite with 30% fiber content was found to be 24 kJ m 02 . Significant improvement in the tensile strength was observed for composites with silane A172-treated fibers. Scanning electron microscopic studies were carried out to understand the fiber-matrix adhesion, fiber breakage, and failure topography. The PALF polyester composites possess superior mechanical properties compared to other cellulose-based natural fiber composites. q 1997 John Wiley & Sons, Inc. J Appl Polym Sci 64: 1739-1748, 1997
