“…Among these, cellulose is one of the most ample polymers, with its annual production being about 1.5 × 10 12 tons [2]. Many studies have proven that natural fibers or cellulosic fibers could become an alternative mineral/inorganic reinforcing fiber in composites [3][4][5][6]. Whilst natural fibers consist of many benefits-such as low density, biodegradability, abundance, and renewability-pristine lignocellulosic fillers are constrained in industrial usage because of their insufficient mechanical properties, even though they possess good specific mechanical properties at low density [3].…”

Microfibrillated cellulose (MFC) particles were synthesized by a low-pressure alkaline delignification process, and their shape and chemical structure were investigated by SEM and Fourier transformation infrared spectroscopy, respectively. As a novel electrorheological (ER) material, the MFC particulate sample was suspended in insulating oil to fabricate an ER fluid. Its rheological properties—steady shear stress, shear viscosity, yield stress, and dynamic moduli—under electric field strength were characterized by a rotational rheometer. The MFC-based ER fluid demonstrated typical ER characteristics, in which the shear stresses followed the Cho–Choi–Jhon model well under electric field strength. In addition, the solid-like behavior of the ER fluid was investigated with the Schwarzl equation. The elevated value of both dynamic and elastic yield stresses at applied electric field strengths was well described using a power law model (~E1.5). The reversible and quick response of the ER fluid was also illustrated through the on–off test.

Teknolojinin gelişmesiyle birlikte saf haldeki malzemelerin yetersiz kalmasından dolayı kompozit malzemeler geliştirilmiş ve zamanla kullanım alanları çoğalmıştır. Cam elyaf takviyeli polyester (CTP) kompozit malzemeler, iyi mekanik dayanım, elastiklik, yüksek korozyon dayanımı ve ekonomiklik gibi özelliklere sahip olmalarından dolayı dünyada yaygın kullanıma sahiptirler. Bu nedenle günümüzde CTP kompozitlere farklı takviye ve dolgu malzemeleri eklenilerek malzeme özelliklerinin geliştirilmesi amaçlanmaktadır. Bu çalışma sisal, jüt, kenaf vb. farklı doğal elyaf takviyesi ve cam kürecik, grafit, alümina vb. farklı dolgu maddesi kullanımının CTP kompozit malzemelerin özelliklerine etkisinin incelendiği çalışmaları ele almaktır. Çalışmanın ilk bölümünde genel olarak doğal ve cam elyaf takviyeli polimer kompozitler hakkında bilgi verilmiştir. Çalışmanın ikinci ve üçüncü bölümünde ise CTP kompozit malzemelerde kullanılan doğal elyaf takviyesinin ve dolgu maddelerinin malzeme özelliklerine etkisinin incelendiği çalışmalar sunulmuştur. Yapılan çalışmalarda doğal elyafların ve dolgu maddelerinin farklı üretim yöntemleriyle CTP kompozit malzemelere başarıyla dahil edilebildikleri, malzeme özelliklerini iyileştirici etki yapabildikleri ve maliyeti düşürebildikleri görülmektedir.

“…Interest in finding and using natural source‐based reinforcement materials is increasing because of requirements for developing eco‐friendly materials and reducing the exhaust due to petroleum‐based materials. Many types of eco‐friendly additives have been successfully used for developing bio‐based composites, such as microfibrillated cellulose, bacterial cellulose, silk fibroin, and epoxidized natural rubber . Vegetable oil and its derivatives are among the most natural additives for biocomposite preparation.…”

Carboxyl-terminated poly(acrylonitrile-co-butadiene) (CTBN)-grafted epoxidized linseed oil (ELO) (CTBN-g-ELO) was synthesized and used as an effective toughener to simultaneously enhance the mechanical properties and fracture toughness of epoxy resin (EP). The ELO was fabricated from linseed oil via epoxidation processing. The characteristics of the ELO and CTBN-g-ELO, such as the average molecular weight and chemical structure, were determined using gel permeation chromatography, proton nuclear magnetic resonance, and Fourier transform infrared spectroscopy. The effects of the CTBN-g-ELO loading on the characteristics of the EP were investigated in detail. The test results indicated that by adding 15 phr CTBN-g-ELO, the tensile strength, impact strength, and critical stress intensity factor (K IC ) were significantly increased, by approximately 23.62, 91.8, and 33.8%, respectively, compared with pristine EP. The glass-transition temperature (T g ) and storage modulus, which were examined via dynamic mechanical thermal analysis and differential scanning calorimetry, respectively, exhibited decreasing trends. Scanning electron microscopy revealed that the CTBN-g-ELO existed as spherical particles in the EP, helping to stop the crack growth and change the crack growth directions.
