Seneviratne, W.P., & Tomblin, J.S., inventors; Wichita State University, assignee. Composite window plug. United States patent US 20250304236 A1. 2025, October 2.
Abstract
A composite window plug can be used to plug a window frame in an aircraft, for example, during aircraft conversion and modification services. The composite window plug is formed from a stamped composite laminate and an over-molded rib structure fused to the interior surface of the stamped composite laminate. The over-molded rib structure has multiple ribs extending inwards from a perimeter rib to form a stiffening pattern. The stamped composite and the over-molded rib structure may include a thermoplastic material reinforced with fibers. The composite window plug can be formed in a stamping and over-molding process conducted in a single mold.
