  • Patent number: 12365204
    Abstract: In a pneumatic tire, a bead core has end portions in a tire width direction formed as vertical lines along a tire radial direction. A length of the vertical lines is from 20% to 30% of a core height. In two adjacent bead core layers of first, second and third layers, the radial outer layer tire includes two or more bead cores more than the radially inner layer tire, and a misalignment amount between the bead wires each at an end portion on one side in the tire width direction is one-half of a bead wire thickness. A side on which the misalignment amount between the first and second layer bead wires is one-half of the thickness of the bead wire is opposite in the tire width direction to a side on which the misalignment amount between the second and third layer bead wires is one-half of the thickness of the bead wire.

  • Publication number: 20250234456
    Abstract: A method for producing a prepreg, includes the steps of (1) an opening step of opening glass fiber bundles to form plural glass fiber filaments, and (2) a step of aligning the plural glass fiber filaments formed in the previous opening step, on a thermosetting resin composition-coated surface of a carrier material so as to make the filaments run nearly parallel to each other in one direction thereon to form a prepreg. A method for producing a laminate, includes a step of preparing two or more prepregs formed in the previous step (2), laminating them in such a manner that, in at least one pair of prepregs, the running direction of the plural glass fiber filaments in one prepreg differs from the running direction of the plural glass fiber filaments in the other prepreg, and heating and pressing them.

  • Patent number: 12256490
    Abstract: Provided is a prepreg capable of attaining thermal expansion coefficient reduction and elastic modulus increase without increasing the filling ratio of an inorganic filler therein and/or without using a resin having a low thermal expansion coefficient, and thereby capable of reducing warpage thereof. Specifically, provided is a prepreg containing glass fibers and a thermosetting resin composition, and containing a layer of plural glass fiber filaments aligned to run nearly parallel to each other in one direction. Also provided are a production method for the prepreg, a laminate containing the prepreg and its production method, a printed circuit board containing the laminate, and a semiconductor package having a semiconductor device mounted on the printed circuit board.
