“…Some studies have shown difference between the properties of the matrix in the bulk and the matrix near the fiber called the interphase. The interphase is a tridimensional area between the fibers and the matrix which properties differ from both that can be quite difficult to study [21,22]. In the interphase, a decrease of the glass transition temperature (T g ) of the matrix was observed [23].…”

Natural fibers and particularly flax fibers have a great potential to replace glass fibers in composite materials. However, the interaction between these fibers and thermoset matrices remains unclear and results in a weak interface affecting the mechanical properties of the composite. This study was carried out to investigate the impact of natural fibers on the chemical reaction between the resin and the hardener, studying the interaction of fibers with each component separately to understand more precisely the phenomena involved. The results show that the contact with the fibers involves a change of the matrix properties that has been attributed to the water absorbed on their surface. On the one hand, water could modify amine functions of the hardener leading to a decrease of 40°C of matrix glass transition temperature (T g). This issue could be corrected by adding a 16% excess of hardener. On the other hand, the water added to the resin could also accelerate the epoxide/amine reaction increasing slightly the T g of the matrix and also generating weaker distinct networks of lower T g by post-modification of the hardener. Therefore, the control of the water content in flax fibers is a crucial parameter for composite manufacturing.

“…and Karamanlioglu et al ., when the matrix appears to be poorly biodegradable, the mechanisms begin with the other phases . This interface has been the subject of different studies and can be modified by treatments and compatibilizing agents . However, both the additives and the treatments commonly used in natural fibers either raise the cost or impact the environment.…”

“…As for the treatments, several authors have modified the relationship between cellulosic and lignocellulosic components with concentrated acids or bases or high temperatures . In particular, cotton is a natural cellulosic (80–90%) fiber that has avoided strong treatments.…”

Poly(lactic acid) (PLA) is a biodegradable, brittle, and high-cost polymer, which can be applied over structural components and green packaging. In this study, we reinforced PLA with natural cotton (10 wt %) and thermoplastic starch (TPS; 3 wt %) to obtain a biodegradable and lower cost composite. TPS was incorporated in three distinct ways: it was blended, coated, and blended and coated. In this study, we investigated the compatibilization of TPS in the improvement of matrix-reinforcement adhesion and increase in the tensile behavior without a compromise in biodegradation. The samples were investigated with thermal analysis, dynamic mechanical thermal analysis, tensile testing, scanning electron microscopy, confocal laser scanning microscopy, and hydrolytic degradation. The results show that the coupling effect was more pronounced in the PLA TPS -cotton TPS (hybrid system with PLA and cotton) hybrid system. This formulation presented a higher glass-transition temperature, thermal stability, storage modulus, wettability, and ductility. The TPS addition improved the adhesion between the matrix and starched cotton fiber and retarded abiotic biodegradation. These properties will allow for green applications.

“…It is therefore necessary to modify the fiber surface by employing chemical modifications to improve the adhesion between fiber and matrix (Esfandiari, 2008). The biodegradability, low density, a range of mechanical properties, less abrasiveness compared to synthetic fibers make lignocellulosic fibers attractive to be used as reinforcement in polymer matrix composites (Islam and Sharif, 2016;Shubhra et al, 2010;Seki et al, 2010;Biswas et al, 2011). Cotton is one of the most recognized lignocellulosic fibers used in several applications varying from common fabrics to composites (Eleiche and Amin, 1986;Alsina et al, 2005;Fervel et al, 2003;Tserki et al, 2003).…”

Hybrid polymer matrix composites of waste cotton fabric and wood saw dust reinforcements were studied with a view to recycling the wastes from garments and carpentry industries. Polymer composites with cotton fabric and wood-saw-dust reinforcements were fabricated using hot press machine. Their physical, thermal and mechanical behaviors were discussed in terms of moisture absorption, thermal stability, tensile strength, elastic modulus, flexural strength and flexural modulus. Compositional analyses of fibers, matrix and composites were carried out with FTIR spectroscopy. Experimental results revealed that tensile and flexural strength of the composites increased with cotton fabric reinforcement. On the other hand, with increasing wood saw dust strength decreased up to a certain limit and then increased again. Water absorption of the hybrid composites increased substantially with increasing natural filler contents. Maximum water absorption was observed in 20% fabric/wood-saw-dust reinforced polymer composite. Furthermore, TGA graphs suggest better thermal stability of the hybrid composites than that of pure polypropylene. Bangladesh J. Sci. Ind. Res.54(1), 21-30, 2019
