Abstract
The present work studies the impregnation process through a carbon-fiber-reinforced plastic (CFRP) during the resin injection filling stage of a vacuum infusion process by using simulation software PAM-RTM. Our work aims to study the resin injection time of carbon fabric composite laminate based on the type of weaving fabrics, permeability and porosity of reinforced fabric and to define the optimal structure of reinforced fabric based on simulation and experimental results. The resin infusion method procured from simulation and experimental results can effectively avoid the high cost caused by the trial-and-error method.
Highlights
Composite Materials are becoming more popular gradually replacing traditional materials with extra strength, lighter weight, and thermal properties [1-14]
If we compare different manufacturing processes, most of the polymer composite products are made with vacuum infusion technology because of the huge potential to manufacture critical parts with required properties at an economical rate
Various types of resin infusion processing have emerged as popular manufacturing options due to their relatively low costper-properties ratio
Summary
Composite Materials are becoming more popular gradually replacing traditional materials with extra strength, lighter weight, and thermal properties [1-14]. If we compare different manufacturing processes, most of the polymer composite products are made with vacuum infusion technology because of the huge potential to manufacture critical parts with required properties at an economical rate. For the production technology vacuum assisted resin infusion (VARI) process is used. This process is a very attractive composite manufacturing process since large structures can be fabricated cost-effectively. The influence of structure of the reinforced fabric on the duration of the impregnation process by vacuum infusion process was studied. To carry out accurate simulation, knowledge of several experimental parameters such as type of weaving, the resin properties, and the porosity and permeability values of the fiber materials are required. In our study to simulate the impregnation technology, the PAM-RTM software is used, which allows us to determine the duration of the impregnation process
