موضوع به انگلیسی:Mechanical and thermal characterization of bagasse fiber/coconut shell
particle hybrid biocomposites reinforced with cardanol resin
بخشی از متن:The primary aimof this study is to develop a biocomposite by using biopolymer and natural fibers/particles from
renewable resources.With the aid of poly-condensation process, the cardanol thermoset biopolymer resin from
cashew nut shell liquid (CNSL) was synthesized. The abundantly available, bagasse fiber (20 mm of length) and
coconut shell particle (50 μm) were applied as reinforcement material to produce a new ecological hybrid
biocomposite. The prepared fiber and particles are treated chemically. Hybrid composites of Cardanol
(C) reinforced with bagasse fiber (BF), Coconut shell powder (CP) and Bagasse fiber/Coconut shell powder
(BC) were manufactured using a compressionmoulding process. This four different kinds of composites, though
the sequences are done to have C, C/BF, C/CP, and C/BC. The mechanical properties of the prepared biocomposites
were evaluated through tensile, flexural and impact test. These evaluation predicts that C/BF possess comparatively
more strength with other hybrid composites. The presence of fiber and particle are attributed in all the
biocomposites using FT-IR spectroscopy analysis. Similarly during thermal analysis, C/BF corroboratewith higher
thermal stability than other biocomposites by thermal gravimetric analysis
