Patent number: 11897210Abstract: Methods and apparatus involved in the process of hardening a composite part are disclosed herein. The methods include applying a preform to a mandrel, covering the preform with a caul plate, sealing the caul plate to the mandrel, pushing the caul plate toward the preform and the mandrel and hardening the preform into a composite part while the caul plate is held against the preform. The apparatus include a mandrel, a caul plate which defines a surface of a preform and where the caul plate may include a rigid material and seals disposed between the mandrel and the caul plate. In an additional aspect, the apparatus may include a sealed chamber with a mandrel and a caul plate and a circumferential seal between the mandrel and the caul plate.Type: GrantFiled: November 10, 2021Date of Patent: February 13, 2024Assignee: The Boeing CompanyInventors: Daniel R. Smith, Darrell D. Jones, Byron James Autry, James R. Kendall, Raviendra Sidath Suriyaarachchi

Patent number: 11872780Abstract: A method of cutting an uncured composite material is presented. The uncured composite material is positioned onto a surface of a tool and over a groove in the surface, the groove having a groove filler and magnetic material within the groove. A cutter having a guide is positioned relative to the uncured composite material, the guide configured to detect the magnetic material. The uncured composite material is cut above the groove using the cutter as the cutter moves along a path defined by the groove, the cutter guided by the guide detecting the magnetic material in the groove.Type: GrantFiled: June 2, 2022Date of Patent: January 16, 2024Assignee: The Boeing CompanyInventors: Samuel James Knutson, Raviendra Sidath Suriyaarachchi

Patent number: 11845236Abstract: A method for fabricating a composite structure. A first section for the composite structure is formed in which the first section has a first end with a chevron shape, wherein first composite layers in the first section has a first step pattern at the first end. A second section for the composite structure is formed in which the second section has a second end with a counterpart shape to the chevron shape and in which second composite layers in the second section have a second step pattern at the second end. The first end the second end are positioned such that a first composite layer in the first composite layers in the first step pattern overlap the second composite layers in the second step pattern at a splice location.Type: GrantFiled: March 12, 2018Date of Patent: December 19, 2023Assignee: The Boeing CompanyInventors: James R. Kendall, Raviendra Sidath Suriyaarachchi, Paul D. Shaw
