  • Method for measuring a flowing property in a resin transfer molding system
    Patent number: 10946597
    Abstract: The present disclosure provides a measurement method for a molding system comprising an upper mold and a lower mold forming a mold cavity. The method includes applying a pressure difference to a molding resin for driving the molding resin to flow into a preform in the mold cavity; detecting a flow front of the molding resin at a first position and a second position in the mold cavity; and calculating a flowing property of the molding resin based on the first position, the second position, a travelling time of the flow front from the first position to the second position, and the pressure difference.

  • SYSTEM AND METHOD FOR MEASURING A FLOWING PROPERTY IN A RESIN TRANSFER MOLDING SYSTEM
    Publication number: 20180319107
    Abstract: The present disclosure provides a system for measuring a permeability/porosity ratio of a fiber preform in a molding system. In some embodiments of the present disclosure, the system includes a mold, a detection device, a resin-supplying source, and a computing device. The mold includes an upper mold and a lower mold forming a mold cavity. The resin-supplying source is configured to input a molding resin into a preform in the mold cavity. The detection device is configured to detect a flow front of the molding resin at a first position and a second position in the mold cavity. The computing device is configured to calculate a flowing property of the molding resin into the preform based on the first position, the second position, a travelling time of the flow front from the first position to the second position, and a pressure difference driving the flow front to travel from the first position to the second position.
