Zusammenfassung:	To provide composite structures used in aircraft, and more specifically, a lightweight control surface exhibiting high residual strength, improved fracture toughness properties, and damage tolerance.SOLUTION: A thin, lightweight control surface is fabricated by induction consolidation of thermoplastic components. The control surface includes a forward section co-consolidated with a rear section. The front section includes a cover, and the rear section includes a truss core covered by an outer skin.SELECTED DRAWING: Figure 2 【課題】航空機に使用される複合構造、より具体的には、高い残留強度、改善された破壊靱性特性、および損傷許容性を示す軽量の制御面を提供する。【解決手段】薄く軽量の制御面は、熱可塑性構成要素の誘導圧密化によって作製される。制御面は、後方セクションと相互に圧密化された前方セクションを含む。前方セクションはカバーを含み、後方セクションは外板によって覆われたトラスコアを含む。【選択図】図2
