Characterization of VARTM resin candidates for commercial airplane applications

Advancements in low cost processing have greatly increased commercial interest in vacuum assisted resin transfer molding (VARTM) processes, yet manufacturers are struggling to create composite parts with mechanical properties as high as those fabricated with current prcpreg technology, Neat resin and composite material properties of five VARTM resins were evaluated. This work details the screening process and demonstrates that more effort will be required to formulate a commercial VARTM resin capable of meeting or exceeding current prepreg technology.
