“…When a void is present, stresses in the laminate are not able to distribute evenly causing stress concentrations around the area of the void. These stress concentrations can cause the void to grow and eventually result in failure of the laminate (Edmonds and Hickman, 2000). For fiber/matrix composite materials, internal failure can result from fiber breaking, microcracking in the matrix, debonding, and delaminations (Agarwal, 2006).…”

Defects in composite laminates are difficult to detect because of the conductive and paramagnetic properties of composite materials. Timely detection of defects in composite laminates can improve reliability. This research illustrates the preliminary analysis and detection of delaminations in carbon fiber laminate beams using a single layer of magnetostrictive particles and noncontacting concentric magnetic excitation and sensing coils. The baseline analytical models also begin to address the intrusive nature of the magnetostrictive particles as well as relate the applied excitation field with the stress and magnetic flux densities induced in the magnetostrictive layer. Numerical methods are used to begin to characterize the presence of magnetostrictive particles in the laminate and the behavior of the magnetostrictive particles in relationship to the magnetic field used during sensing. Unidirectional laminates with embedded delaminations are used for simulations and experimentations. A novel, yet simplified fabrication method is discussed to ensure consistent scanning and sensing capabilities. The nondestructive evaluation scanning experiments were conducted with various shapes and sizes of damages introduced into carbon fiber-reinforced polymeric composite structures. The results demonstrate high potential for magnetostrictive particles as a low-cost, noncontacting, and reliable sensor for nondestructive evaluation of composite materials.

“…For instance, 40-60% weight reduction is expected by using high-strength titanium alloys and metal matrix composites (MMCs) with oriented continuous fibre reinforcement for early-21st-century aircraft [8]. Allied to advantages in mechanical properties, their excellent thermal, electric and magnetic features are also favorable for aircraft flutter suppression [9], fatigue-crack reinforcement and repair [10,11], debris prevention [12,13], temperature resistance [14], and damage detection [15][16][17][18][19][20]. By way of illustration, applications of composite materials in some typical commercial and military aircrafts are summarized in Table 1 [24], while detailed reviews of their applications can be referred to elsewhere [21][22][23].…”

An adaptive scheme for detecting aircraft aerodynamic damage is presented and analyzed based on a recentlydeveloped linear aircraft dynamic model which captures the structure changes caused by system damage. The proposed adaptive detection design employs a model based approach using the aircraft model structure information, in particular, the coupling of the lateral and longitudinal dynamics. A two-detector algorithm is used, with one detector for a healthy model and one detector for a damage model, to generate two detection errors whose behaviors are compared for detection of a possible damage in the system. Desired damage detection system performance is illustrated by simulation results.
