Embodiment Construction

[0056] The following detailed description refers to the accompanying drawings that illustrate specific embodiments of the present disclosure. Other embodiments having different structures and operations do not depart from the scope of the present disclosure. In different drawings, similar reference numbers may refer to the same elements or components.

[0057] refer to figure 1 , generally designated 10 , may include a composite substrate 12 and a release layer 14 . Composite substrate 12 may include opposing planar surfaces 24 and 26 . Release layer 14 may include opposing planar surfaces 44 and 46 . The release layer 14 may be coated (e.g., attached) to the composite substrate 12 such that the surface 44 of the release layer 14 is in contact with the surface 24 of the uncured or partially cured composite substrate 12 (e.g., the top surface of a single layer of the composite substrate). Or the top surface of the uppermost composite substrate of multiple layers of the comp...

Abstract

A composite structure (10) may include a composite substrate (12), the composite substrate (12) including a surface (24), a peel ply (14), the peel ply (14) including a surface (44), and an identifiable marking agent (32, 52, 54), wherein the surface (44) of the peel ply (14) includes the identifiable marking agent (32, 52, 54), and wherein the peel ply (14) is connected to the composite substrate (12) such that the identifiable marking agent (32, 52, 54) is in contact with the surface (24) of the composite substrate (12).

Description

technical field [0001] The present disclosure relates generally to composite structures, and more particularly, to composite structures having improved surface bonding characteristics and methods for inspecting pre-bonded surfaces of composite structures to verify adequate surface bonding treatment. Background technique [0002] Composite structures have an advantageous combination of high strength and light weight. Likewise, it is common to find composite structures used in aerospace and other industries where these properties are beneficial. For example, the surface skins of modern aircraft may often be formed from composite structures. [0003] The composite structure includes reinforcing fibers impregnated with a resin matrix. Often, there is a need to attach the composite structure to another structure, such as a second composite structure or an internal structural support (eg, a stiffener). The bond strength between composite structures may depend on the surface pro...
