چکیده
Abstract The outstanding mechanical and environmental qualities of hybrid bio-composites have made them popular. drying procedure to remove the moisture before manufacture, on other hand, can take a long period. By modifying macromolecular structure considerably faster, with additional physical treatment utilising microwave energy could improve their capabilities. Fillers 80:15:5, 90:5:5, 98:1:1 coconut fibre rice husk were combined poly-lactic acid (PLA) melt-mixing hot press techniques. fillers dried in conventional oven at 60°C for 24 hours 2.45 GHz 3 minutes. When tensile strength was tested, it discovered that oven-treated fibres composition had higher (63 MPa) than microwave-treated (58 MPa). Microwave-treated fibres, flexural (69 those treated normal (60 Furthermore, when compared plain PLA, enhanced toughness by least 4%. For 80:15:5 composition, lower water absorptivity (2%) conventionally which 5%. SEM images confirmed presence agglutination voids content, resulting poor adhesion low strength.

15 صفحه اولCharacterization of Glass Fibre – Coconut Coir– Human Hair Hybrid Composites
A composite material is a combination of two or more materials arranged in the form of layer one on the other layer using binding material through some prescribed methods. In the Glass fibre coconut fibre human hair hybrid composite method, the epoxy resin is used as binding material, in which one layer is formed of glass fibre, followed by coconut fibre and then by human hair. By using hand la...
متن کاملExperimental data on the properties of natural fiber particle reinforced polymer composite material
This paper presents an experimental study on the development of polymer bio-composites. The powdered coconut shell, walnut shells and Rice husk are used as reinforcements with bio epoxy resin to form hybrid composite specimens. The fiber compositions in each specimen are 1:1 while the resin and hardener composition 10:1 respectively. The fabricated composites were tested as per ASTM standards t...

This paper investigated the moisture absorption, mechanical behavior and the dielectric performance of hybrid and non-hybrid polymeric composites. Hand lay-up technique was used for processing carbon; glass reinforced polyester resin composites (non-hybrid) and carbon-glass/polyester hybrid composites with various fiber configurations. The maximum resistance of water absorption was obtained for...
