The optimization of parameters for the Impregnation
process in order to produce high-quality prepregs with high
impregnation quality is challenging. The purpose of the study is to
access the applicability of full factorial experimental design 2 3 in
predicting properties of polymer composite prepregs. This paper
presents an experimental study of the impregnation of aramid
cloth with thermosetting resin matrix. Experiments (DoE) method
is used to create quality prepreg and to find optimized input
parameters for this technology. The major benefits gained of the
current study are that the thickness of film is an important
parameter, which has a prominent effect on the final product. A
model is developed to describe the resin content as functions from
thickness film, temperature and impregnation velocity in
horizontal impregnating process. Results are obtained
methodically through the separation of variables.
The methods and results presented in this paper offer a
valuable insight of how to measure the quality and how to use this
information for the optimization of Impregnation processes
Experimental studies were performed with changing parameters
– temperature, thickness of film and speed. Finally, it describes the
content of resin inside of the composites. The resin content is
controlled by a combination of the thickness resin film, the
impregnation velocity and the oven temperature. These properties
are good enough for aramid fabric prepreg to be used as
engineering materials in many structural applications.
