Publication number: 20180319107Abstract: 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.Type: ApplicationFiled: March 14, 2018Publication date: November 8, 2018Inventors: Yuan YAO, Tzu-Heng CHIU, Rong-Yeu CHANG, Chia-Hsiang HSU, Chih-Wei WANG, Shih-Po SUN, Sung-Wei HUANG, Hsun YANG, Tsai-Heng TSAI

Publication number: 20180319112Abstract: A method of manufacturing a pneumatic tire including forming a green case by cylindrically winding a tire component member which includes at least one layer of a carcass ply. The green tire is shaped by expanding the green case into a toroidal shape with the supply of a fluid into the green case so that the green case adheres to a tread ring arranged radially outside the green case. The green tire is subjected to vulcanization molding within a mold die. During the shaping of the green tire, the fluid is supplied in accordance with a pressure profile which changes in a stepwise manner. The pressure profile is set such that a former stage pressure which allows the green case to expand to 35% to 40% of a full expansion amount is set lower than a final stage pressure in a final stage.Type: ApplicationFiled: July 18, 2018Publication date: November 8, 2018Applicant: Toyo Tire & Rubber Co., Ltd.Inventor: Kunihiko Nagai
