“…, the impact force and load curve under different impact energy values are different. These results are in agreement with those reported previously, where materials are prepared by resin transform molding . With increasing impact energy, the span of the impact load curve decreases, that is, the impact contact time decreases.…”

Fiber-reinforced prepreg composites are considered to be the most promising materials for aerospace applications. However, these composites are susceptible to impact during in-service phases. The impact can cause various types of damage, such as matrix cracks, delamination and fiber breakage, thereby considerably decreasing their mechanical properties. In this study, a series of experiments were carried out to investigate the LVI characteristics. The impact damage characteristics of the fiber-reinforced prepreg composites were examined; the influencing factors and rules of impact damage were investigated; and the damage process and failure mechanism were revealed. X-ray 3D computed tomography was employed to examine the internal damaged state of the fiber-reinforced prepreg composites. An experimental study was carried out to investigate their compression after impact performance. The results indicated that impact energy mainly affects damage failure. With increasing impact energy, the impact contact time decreases, while the impact force fluctuation increases. The damage zone was spherical, and the damaged area increased with energy. The impact damage led to the sharp decrease in the remaining compressive strength and stiffness of the material, and the residual compression strength and stiffness were decreased to 62.25 and 76.6%, respectively.

“…In contrast, at low temperatures (e.g. 25°C and 50°C), Russo et al [320] have investigated the low-velocity impact response of thermoplastic composite laminates derived from thermoplastic polyurethane reinforced with woven glass fibers. To confirm the possible applications of these materials, they reported that low-temperature impacts led to a raised stiffness of tested composites and a higher propensity to fail.…”

“…On the contrary, at low temperatures (e.g. À25 and À50°C), Russo et al have studied the low velocity impact behavior of TP laminated structures based on TP polyurethane reinforced with woven glass fibers [21]. In order to verify the potential applications of these materials, they concluded that low temperature impacts result in an increased stiffness of tested specimens and a higher propensity to damage.…”

Impact damage tolerance of hybrid carbon and glass fibers woven-ply reinforced PolyEther Ether Ketone (PEEK) thermoplastic (TP) laminates obtained by consolidation process is investigated. Service temperature being one of the most important parameters to screen TP or thermosetting matrix for aeronautical purposes, impact testing at room temperature (RT) and near the glass transition temperature (Tg) has been conducted. From the results, it turns out that temperature has little influence on the impact behavior in terms of maximum force developed or maximum deflection, though it reduces the dissipated energy especially at lower impact energy. However, temperature has a strong effect on the internal and external damages caused to the plate, as it increases the permanent indentation and it limits the projected delaminated area. As for the influence of temperature on the compressive residual strength of the laminates, it also appears that the classical experimental setup for CAI tests is not completely appropriate to draw a clear cut conclusion. At last the obtained results show that the considered TP-based laminates are characterized by a very good impact behavior and a high-degree of damage tolerance.
