Problems solved by technology

The current approach utilizes stringers attached to the skin panels to provide stiffness, but since the extra wing depth may increase aerodynamic drag, the size of the stringers must be kept to a minimum, especially on the outermost part of the wing
Additionally, the manufacturing process for composites includes extensive manual lamination work, which can result in undesirably high costs and low yields

Abstract

Hybrid composite panel systems (120) and methods are disclosed. In one embodiment, an assembly includes a primary section (126), a matrix member (136) engaged with the primary section (132), and a secondary section engaged with the matrix member opposite the primary section. The primary section includes a plurality of first composite layers reinforced with a first reinforcing material, and the secondary section includes a plurality of second composite layers reinforced with a second reinforcing material. The primary and secondary sections are configured to bear an operating load at least partially transversely to the first and second composite layers, and are asymetrically configured such that the primary section bears a majority of the applied operating load.

Description

technical field [0001] [0001] The field of the present disclosure relates to composite panel systems and methods, and more particularly, to asymmetric composite panels formed using a hybrid process of automated and non-automated manufacturing activities. Background technique [0002] [0002] The utilization of composite materials in various industries continues to expand due to their favorable strength and weight characteristics. The increasing use of composite materials and composite structural components in aircraft manufacturing has led to significant weight savings in aircraft. These weight savings translate into significant improvements in fuel economy and substantial reductions in operating expenses and atmospheric emissions. For example, due to the extensive use of composite materials on a large scale, it has been estimated that aircraft may consume an estimated 20% less fuel than contemporary comparison aircraft. [0003] [0003] The feasibility of forming a structur...
