Influence of process pressures on filling behavior of tubular fabrics in bladder-assisted resin transfer molding

Among the family of liquid composite molding techniques, bladder-assisted resin transfer molding (BARTM) enables efficient manufacturing of hollow composite parts based on tubular reinforcing textiles. However, resin injection under certain processing conditions can result in high filling times or i...
