“…Because of their versatile properties, improved safety and economic aspects, polymer composites are more frequently used, particularly in the construction industry, aviation and automotive industry (Datta and Kopczyńska 2015;Naheed et al 2014;Mówczyński 2012;Bledzki et al 2006). Composites are employed in complex constructions, and layered and construction materials.…”

In our study, we focused on obtaining biopolyurethane composites using bio-components such as bio glycol, modified natural oil-based polyol, and microcrystalline cellulose (MCC). The pre-polymer method was used to prepare the bio polyurethane matrix. Prepolymer was synthesized using 4,4 0 -diphenylmethane diisocyanate and a polyol mixture containing 50 wt% of commercial polyether and 50 wt% of hydroxylated soybean oil (H3). Bio based 1,3-propanediol (1,3bioPDO) was used as the prepolymer chain extender. The composites were produced by dispersing 5, 10, 15 and 20 wt% of MCC in the bio polyurethane matrix. The polymerization was catalyzed with 1,4-diazabicyclo[2.2.2]octane. The influence of the added MCC powder on the structure and thermal properties of the obtained composites was investigated. The FTIR analysis demonstrated that the MCC admixture affected the absorbance of C-O-C and C=O groups and the phase separation index of the obtained bio-polyurethanes composites. The results of mechanical tests and scanning microscopy images indicated good interfacial adhesion between the partially bio-based matrix of the composite and bio-filler. The results of thermomechanical analysis showed that the application of MCC as a filler has a positive effect on the storage and loss modulus of the composites.

“…First of them is related to the modification of the polymer matrix [55,56], while second is focused on size reduction [57], treatment or functionalization of cellulosic filler/fiber. In this subchapter we will focus on the second route related to the surface of filler/fiber, which can be successfully modified by silane treatment [58,59], mercerization [60,61], acetylation [62,63] maleic anhydride treatment [64], esterification and etherification [65,66], isocyanate [67], potassium permanganate [68] and other chemical treatment methods [69][70][71]. Furthermore, different kinds of surfactants and plasticizers applied as physical additives were considered as wetting agents to reduce the tensions in boundary between polymer matrix and reinforcement phase [72][73][74].…”

Abstract.Reactive extrusion is a cost-effective and environmentally-friendly method to produce new materials with enhanced performance properties. At present, reactive extrusion allows in-situ polymerization, modification/functionalization of polymers or chemical bonding of two (or more) immiscible phases, which can be carried out on commonly used extrusion lines. Although reactive extrusion has been known for many years, its application for processing of bio-based polymer blends and composites is a relatively new direction of scientific research. This work presents a literature review on recent advances in the processing of bio-based polymer blends and composites via reactive extrusion. We described compatibilization mechanisms for different types of biodegradable polymeric materials based on: (i) aliphatic polyesters, (ii) aliphatic polyesters/starch and (iii) aliphatic polyester/natural rubber systems. A special attention was focused on conventional and dynamic cross-linking of bio-based polymer blends and composites as an effective way to prepare new materials with unique properties e.g. biodegradable thermoplastic elastomers or shape-memory materials. Advantages and limitations affecting future trends in development of biodegradable polymer blends and composites reactive extrusion are also discussed.

“…Thus, various researchers have studied the physical and mechanical properties of natural fiber-reinforced polymer composites [9][10][11][12]. Lower density leads lower-weight structures in the automotive industry and aerospace applications [13][14][15][16]. Mechanical properties such as tensile properties, flexural properties and impact strength are strongly affected by fiber content, as shown in Figure 2 [17].…”

Abstract. In recent development, natural fibers have attracted the interest of engineers, researchers, professionals and scientists all over the world as an alternative reinforcement for fiber reinforced polymer composites. This is due to its superior properties such as high specific strength, low weight, low cost, fairly good mechanical properties, non-abrasive, eco-friendly and bio-degradable characteristics. In this point of view, natural fiber-polymer composites (NFPCs) are becoming increasingly utilized in a wide variety of applications because they represent an ecological and inexpensive alternative to conventional petroleum-derived materials. On the other hand, considerable amounts of organic waste and residue from the industrial and agricultural processes are still underutilized as low-value energy sources. This is a comprehensive review discussing about natural fiber reinforced composite produced by filament winding technique.
