Project Background:
Fiber reinforced thermoplastic composite bar has the advantages of repeated molding, high toughness/durability and recyclability. The bending process and forming method of thermoplastic composite bar are the key to preparing the concrete stirrups. At present, there is a lack of efficient bending devices for thermoplastic stirrups. In addition, the technologies for improving the mechanical properties of thermoplastic composite stirrups and the design methods of concrete structures are key to promoting the demonstration application of marine engineering.
Aims & Goals:
1. To develop a bending device and forming method for thermoplastic stirrups that meet the rapid bending needs on site;
2. To reveal the formation mechanism of fiber dislocation, crack defect of thermoplastic composite stirrups;
3. To establish a theoretical calculation model for the bending strength of thermoplastic composite stirrups.
