Zusammenfassung:Methods and apparatus to increase strength and toughness of aircraft structural components are disclosed. An example apparatus includes a composite structure of an aircraft, a stringer coupled to the composite structure of the aircraft, where the stringer and the composite structure form a stringer radius gap. A gap filler is disposed in the stringer radius gap, which includes chopped fibers randomly distributed throughout an entire volume of the gap filler. Il est décrit des méthodes et appareils servant à améliorer la force et la résilience de composants structurels daéronefs. Un appareil servant dexemple comprend une structure composite dun aéronef et une lisse couplée à cette dernière, lesquelles composantes forment un espace du rayon de la lisse. Un agent de remplissage de lespace disposé dans lespace du rayon de la lisse, lequel agent comprend des fibres tranchées distribuées au hasard dans lensemble du volume de lagent de remplissage de lespace.
