EFFECT OF IN-SITU STAMPING PROCESS PARAMETER ON GFRTP VISCOSITY AND PARAMETER OPTIMIZATION

Abstract

Abstract: Because of the high viscosity properties of GFRTP and vertically stamping and debonding in the in-situ stamping process, the adheres and detach between the mold and prepreg becomes an very important factor for forming effect. In order to study the influence on viscosity under different paremeters and optimize the combination of the parameter, probe test was used to analyze the viscosity. To define the maximum debonding force to present viscosity, and analyze the influence of important process parameters on viscosity and obtain the optimal parameter combination using the control method and RSM, the results show that the viscosity increase first and then decrease with the increase of temperature, increase with the increase of pressure, increase first and then decrease or remains still with the increase of pressure time. And there is a strong coupling relationship between the process parameter. It provides a theoretical guidance for the subsequent in-situ stamping process.

Key words: thermoplatic composite prepreg, probe tese, viscosity, process parameter, RSM
