DATADVANCE and Skoltech successfully accomplished the project on optimization of pultrusion process parameters

 

DATADVANCE with the Skolkovo Institute of Science and Technology (Skoltech) have successfully solved the task of optimizing manufacturing parameters of composite beam pultrusion process using the DATADVANCE's design space exploration platform pSeven. 

The purpose of the project was to develop methods for numerical optimization and sensitivity analysis of pultrusion process parameters. With this objective in mind, a mathematical model of material behavior is implemented within the ABAQUS environment, accounting for the dependence of matrix thermomechanical characteristics on temperature and degree of polymerization, the rate of chemical reaction of thermoset matrix polymerization, and thermal and mechanical contact with a die. Modeling methods developed describe a temperature field distribution, a degree of curing and a stress-strain state in a material during pultrusion process. For numerical optimization and sensitivity analysis of process parameters the special simulation scheme was developed using pSeven software suite.

Thanks to pSeven, beam production time was reduced by 20% while providing high degree of polymerization and minimum beam deformation during the process.

"We plan to continue studying mathematical models of pultrusion together with DATADVANCE's experts. One of the most interesting tasks is to optimize production parameters considering uncertainties in material properties", 
says Skoltech's senior researcher Alexander Safonov.

Detailed results of this work will be presented at The European Conference on Composite Materials (ECCM17) and The SAMPE Long Beach 2016.

ECCM is Europe‘s leading conference on composite materials. As such the Munich event will follow the long tradition of the ECCM conference series with a wide scope of topics in composite technologies. The conference will attract internationally renowned scientists and engineers in the field of aerospace, automotive and mechanical engineering and will bring together the scientific and the application-oriented world.

The SAMPE Conference and Exhibition in Long Beach is the only event exclusively dedicated to advanced materials and processes. This event attracts an international audience of 3,000+ attendees annually.
