According to global market analysis, annual production of polymer composites is expected increase by an average 6%, reaching a volume 13-14 million tonnes 2024, primarily in the building industry and mechanical engineering sectors. Recycling can be achieved through secondary use or recycling solid waste. In Russia, about 160 out 343 producers are engaged recycling, with focus on thermoplastics....

There are two common types of polymers (thermoplastics and thermosets), which have been classified by various methods depending on their molecular structures. The bonding chains is the fundamental physical difference between these polymer types. named based general thermal processing characteristics, chemical structure, in turn significantly influence properties.

Over the past decade, thermoplastics have been used as alternative substrates to glass and Si for microfluidic devices because of the diverse and robust fabrication protocols available for thermoplastics that can generate high production rates of the desired structures at low cost and with high replication fidelity, the extensive array of physiochemical properties they possess, and the simple s...

As a new and innovative processing method for fabrication fiber-reinforced thermoplastic composites (CFRTs), the feasibility of ultrasonic welding technology was proven in several studies. This offers potential direct manufacturing CFRT–metal structures via embedded pin structures. Despite previous studies, deeper understanding process energy input whether fibers work as directors consequently ...
