Efficient polymerization and crystallization kinetics coupling of polyamide 6 synthesis for liquid composite molding process modeling

Coupled Flow-thermal Scalable Process Modeling Simulations in Liquid Composite Molding of Composite Structures

Net-shape liquid composite molding (LCM) processes for the manufacturing of composite structures involve the permeation of a reactive thermoset polymeric resin through complex, fiber woven preforms. The physical behavior during the processing thus involves coupled multi-physics phenomena consisting of mass, thermal and species transport. The flow process models based on conservation of mass are...

Finding efficient frontier of process parameters for plastic injection molding

Product quality for plastic injection molding process is highly related with the settings for its process parameters. Additionally, the product quality is not simply based on a single quality index, but multiple interrelated quality indices. To find the settings for the process parameters such that the multiple quality indices can be simultaneously optimized is becoming a research issue and ...

Synthesis of Polyamide 6 by Anionic Polymerization of ε-Caprolactam in an Internal Mixer: Effect of Polymerization Reaction Time

The main objective of the present work was to synthesis polyamide 6 through anionic polymerization of ε-caprolactam in an internal mixer. The reaction time and the rheological properties of samples during the polymerization were studied. The samples were characterized by Thermo Gravimetry Analysis (TGA), Differential Scanning Calorimeter (DSC) and FT-IR spectrometer. The melt flow behavior and ...
