However, in addition to the advantages of the VARTM process, there are also disadvantages/defects, mainly materialized by fiber misalignment and voids. This can be a large benefit when completing large projects, such as entire bridge decks or large concrete structures. Upton, R.L. This method of molding offers a short cycle time, easy automation, a high degree of productivity and dimensional stability. Therefore, these materials are replaced by CFRP and GFRP composites. Due to the fiberglass being inside the concrete and the addition of additives and acrylic co-polymer the price is steeper. Therefore, the surface detail and surface roughness may be good on the mold-side, but poor on the open-side. ; Tajik, M.; Pellicano, F.
