Moreover, the simple part processing, high possible degree of shape complexity and easy modification of the design lead to a wide range of part sizes. Furthermore, a major advantage of the RTM process is the use of low value-added materials (low-viscosity resins and dry fibers) that should not be stored in freezers, thus reducing the handling and material costs. Further, the upper half-mold is installed, and vacuum is applied to the mold cavity, where a vacuum pump evacuates the entrapped air. The main advantages of the method are offered by the flexibility for tooling design and material selection, simplicity of changing the geometry of the mold, obtaining complex composites with enhanced quality, god-bearing and structural strength. There are different names to describe this process, namely vacuum-assisted resin infusion (VARI), vacuum-assisted resin infusion molding (VARIM), vacuum bag resin transfer molding (VBRTM) and vacuum injected molding (VIM).

However, the most common fibers for FRP production are glass fibers (GFs) and carbon fibers (CFs). 2. In addition, due to the increasing thickness on a rotation mandrel, the FRP composites obtained by the FW process exhibit a lot of residual stresses. All these defects lead to a decrease in strength and modulus, which finally initiates a premature failure of the composite. most exciting work published in the various research areas of the journal. Resin transfer molding (RTM), also called liquid molding, is a well-established FRP composite fabrication process. Moreover, the exact time (from tens of minutes to hours) and temperature (up to 180 C) for curing mostly depend on the type of material that is autoclaved.
