TGA and DTGA curves of pure and filled PA 66 with glass and basalt fibers were presented in, At a heating rate of 20 C/min, the TGA curve of pure PA 66 (black square points) showed one step of thermal degradation as a result of random chain scission process. June 2022 - You are accessing an old version of our website. I already have a bachelors degree from UCalgary. Depending upon the content, the presence of added fibers (both BF and GF) to PA 66 matrix could speed up or slow down the polymer decomposition by heat. The introduction of BF and GF in PA 66 polymer, regardless of content, always led to an increase in crystallization and melting temperatures, and to a similar reduction in crystallinity degree and glass transition temperature. Contrary to glass fiber (GF) production, no additives (chemicals, solvents, pigments, or hazard materials) are applied during the manufacturing process of basalt fibers [, Due to the growing attention of governments and environmental agencies towards the increasing amount of waste products abandoned in the landfill and polluting disposal operations, several solutions are proposed to recover plastic waste [, For these reasons, basalt fibers are also considered green, sustainable, natural materials that do not create environmental problems, pose pollution issues, and produce less risks for the health and safety of humans [, Basalt-based composites have been proposed for application in transportation infrastructure [, However, until now, the effect of basalt fibers to improve the mechanical and thermal properties of polymer matrices has not been fully investigated [, Polyamide (PA) is the first synthetic thermoplastic semicrystalline polymer, well-known by the name of Nylon.
