#Vacuuminfusion (also known as vacuum-assisted resin transfer molding or VARTM) is a closed-mold composite manufacturing process where dry fiber reinforcements (like fiberglass or carbon) are laid in a mold, sealed under vacuum, and then impregnated with resin. This method pulls out air voids, ensures even resin distribution, and achieves a precise fiber-to-resin ratio (often around 50/50 or better), resulting in parts that are stronger, lighter, and more uniform than traditional hand-layup tech
