“…This, in turn, means that no important damage occurred, but only micro-cracks in the matrix. This may be regarded as the initiation phase of the impact damage [6][7][8], as, on the other hand, was already demonstrated through the use of infrared thermography within impact tests on GFRP specimens [2]. However, the presence of micro-cracks in the matrix does not alter the acoustic characteristics of the material.…”

Infrared thermography is utilized to gain new information on onset and propagation of impact damage in Carbon Fibre Reinforced Polymers. Impact tests are carried out with a modified Charpy pendulum while the SC6000 camera views the specimen surface opposite to impact and records sequences of thermal images at 96 Hz. The same infrared camera, equipped with the lock-in option, is also used for non-destructive evaluation of the specimens before and after impact; results are shown as phase images. The elastic waves propagating from the impact are also recorded with piezo patches. A good agreement is found regarding the damage onset.

“…The maximum use of a composite material in an aircraft structure can be found in the manufacturing of Boeing 787 airliners, 50% of which have now been replaced by carbon fiber reinforced polymer (CFRP) composites. Despite the substantial merits and successful uses of the composite materials as various structural building blocks, especially in aerospace applications [2], there also has been concern that carbon fiber reinforced composites are susceptible to low-velocity impacts that may cause significant damage, such as matrix cracking, interlayer delamination, fiber-matrix interfacial disbanding and fiber breakage [3][4][5][6][7].…”

Impact damages induced by a low-velocity impact load on carbon fiber reinforced polymer (CFRP) composite plates fabricated with various stacking sequences were studied experimentally. The impact responses of the CFRP composite plates were significantly affected by the laminate stacking sequences. Three types of specimens, specifically quasi-isotropic, unidirectional, and cross-ply, were tested by a constant impact carrying the same impact energy level. An impact load of 3.44 kg, corresponding to 23.62 J, was applied to the center of each plate supported at the boundaries. The unidirectional composite plate showed the worst impact resistance and broke completely into two parts; this was followed by the quasi-isotropic lay-up plate that was perforated by the impact. The cross-ply composite plate exhibited the best resistance to the low-velocity impact load; in this case, the impactor bounced back. Impact parameters such as the peak impact force and absorbed energy were evaluated and compared for the impact resistant characterization of the composites made by different stacking sequences.

“…Karakuzu et al, [9] carried out both experimental and numerical analysis to examine some parameters such as the effects of impact energy, impactor mass and impact velocity on the maximum contact force, maximum deflection, contact time, absorbed energy, and overall damage area of glass/ epoxy laminated composites. Aslan et al, [10]- [11] presented a numerically and experimentally study to investigate the effects of the impactor velocity, thickness and in-plane dimensions of target and impactor mass on the response of laminated composite plates under low velocity impact. Sabancı and Karakuzu, [12] investigated the impact behavior of laminated composites with embedded delaminations.…”

In this study, the influence of size and location of embedded delamination on impact behavior of laminated composite was investigated, experimentally. The specimens were produced as for with and without delamination by vacuum assisted resin infusion molding method (VARIM). CEAST-Fractovis plus impact test machine was used in the experiments.As a result of the experiments, the location of delamination on the impact behavior was seen to be more effective than the size of delamination.
