UpcomingTest methods for the experimental characterization of in-plane permeability of fibrous reinforcements for liquid composite moulding
复合材料液体成型用纤维增强材料面内渗透特性的试验表征方法
Application Summary AI generated
This standard specifies test methods for measuring the in-plane permeability of fibrous reinforcements used in liquid composite molding (LCM) processes, such as resin transfer molding (RTM) and vacuum-assisted resin infusion. It is applied in the composites manufacturing industry to characterize how easily resin flows through dry fiber preforms, enabling process simulation and quality control for producing parts like aerospace components, automotive body panels, and wind turbine blades. The standard ensures consistent, reproducible data for optimizing mold design and reducing defects during liquid resin infusion.
