“…Glass-fiber-reinforced polymer composites make up about 90% of all polymer fiber composites used in industry. Glass fibers in the form of roving, mats, fabrics, and chopped fibers are mainly used in the manufacture of boat hulls, yachts, tanks, bathtubs, roof gutters, pipes, and machine housings [5,39]. To improve the mechanical properties of epoxy-glass composites, Tate et al separately introduced 6, 7, and 8 wt% of nanosilica, 20 nm in size, into the matrix.…”

Polymer fiber composites are increasingly being used in many industries, including the defense industry. However, for protective applications, in addition to high specific strength and stiffness, polymer composites are also required to have a high energy absorption capacity. To improve the performance of fiber-reinforced composites, many researchers have modified them using multiple methods, such as the introduction of nanofillers into the polymer matrix, the modification of fibers with nanofillers, the impregnation of fabrics using a shear thickening fluid (STF) or a shear thickening gel (STG), or a combination of these techniques. In addition, the physical structures of composites have been modified through reinforcement hybridization; the appropriate design of roving, weave, and cross-orientation of fabric layers; and the development of 3D structures. This review focuses on the effects of modifying composites on their impact energy absorption capacity and other mechanical properties. It highlights the technologies used and their effectiveness for the three main fiber types: glass, carbon, and aramid. In addition, basic design considerations related to fabric selection and orientation are indicated. Evaluation of the literature data showed that the highest energy absorption capacities are obtained by using an STF or STG and an appropriate fiber reinforcement structure, while modifications using nanomaterials allow other strength parameters to be improved, such as flexural strength, tensile strength, or shear strength.

“…In the aerospace industry, fiber-reinforced composites are often used to reduce the weight of an aircraft owing to their high specific strength and stiffness (Prashanth et al, 2017). However, these composites are inevitably subjected to impact from foreign objects during service and maintenance that causes damage and eventually leads to catastrophic structural failure.…”

Impacts can degrade the strength of composite structures; thus, impact damages should be monitored and repaired. In this study, a novel composite consisting of carbon nanotube film and glass fiber-reinforced thermoplastic was thermoformed. The fabricated smart composite demonstrated self-sensing and self-healing capabilities for damage caused by low-energy impacts. Elastic deformation of the composite caused by a 0.5-J impact was monitored from the immediate change in resistance of approximately 0.25 Ω. Internal damage such as tears and debonding was detected in real time by monitoring the permanent resistance variation of approximately 0.4 Ω using a Wheatstone bridge with a 3-J impact on the smart composite. This difference occurs because a 3-J impact discontinues the conductive path of the carbon nanotubes and changes the total resistance of the smart composite. The internal damage caused by a 3-J impact was repaired through the Joule heat effect when 0.7 MPa and 55 V were applied to heat the composite to 330°C. A three-point bending test demonstrated that the self-healing efficiency of the smart composite reached 87% in terms of flexural strength.

Smart structures can help to resolve many issues related to conventional materials that are being used in different industries. Shape memory alloys (SMAs) are smart materials with better actuation response, vibration damping characteristics, and large strain recovery, making them good candidates due to their high strength and corrosion resistance for various engineering applications. The performance of fiber-reinforced polymer (FRP) composite materials that are replacing many conventional materials due to their good strength, stiffness, and lightweight potential especially in fuel-consuming industries such as aerospace and automotive, can further be improved by impregnation with SMAs. This review discusses the SMA-reinforced FRP composites, leading to shape memory hybrid composite materials, the issues and limitations in composite manufacturing, and their uses in different research arenas including impact and damping applications, seismic protection applications, crack closure applications, shape morphing applications, and self-deployable structures.
