Summary: High-performance ballistic fibers, such as aramid fiber and ultra-high-molecular-weight polyethylene (UHMWPE), are commonly used in anti-ballistic structures. However, their limitations in certain structures have led to the investigation of hybrid materials. The combination of aramid fiber reinforced epoxy resin matrix composites (AFRP) and carbon fiber reinforced epoxy resin matrix composites (CFRP) has shown improved stiffness and ballistic performance.

Summary: This paper characterizes and analyzes the low-velocity impact responses and damage mechanisms of CF/PEEK-Ti hybrid laminates with nano-interfacial enhancement by multi-walled carbon nanotubes (CNTs). The results show that interfacial enhancement of CNT network effectively increases the initial delamination thresholds and improves the mechanical performance and damage tolerance of the laminates. The proposed unified constitutive model provides guidance for the structural design and engineering applications of FMLs.

Summary: This paper presents an experimental study on the repeated low-velocity impact behavior of inter-ply hybrid composites. The impacts were performed using a drop-tower apparatus following ASTM D7136 Standard. A double exponential empirical model is proposed to describe the degradation due to the repeated impacts, considering the hybridization ratio. The results show that hybridization may lead to the mitigation of repeated impact degradation, with asymmetric hybrids outperforming single-fiber laminates.

Summary: This study investigates the flexural, impact, and elastic properties of non-woven curaua-aramid fabric hybrid epoxy composites. The results show that replacing aramid layers with curaua leads to a decrease in flexural strength, flexural modulus, and energy absorbed in the Charpy impact test. The impulse excitation technique also demonstrates a decrease in elastic properties with the replacement of aramid layers. However, reduction maps reveal the advantages of hybridizing curaua with aramid fiber, resulting in a continuous and homogeneous material with improved impact resistance.

Summary: This paper investigates the effect of impact damage on the fatigue behavior of CF/PEEK-titanium hybrid laminates. A fatigue life model is proposed to predict the S-N curves of the laminates based on energy dissipation approach. The energy dissipation behavior of the laminates under different experimental conditions is analyzed through post-impact fatigue tests, and the correlation between impact damage and fatigue dissipation energy is determined. The validity of the proposed model is verified through fatigue tests under different stress ratios and impact energy levels.

Summary: The study found that using two fillers at the interface of glass fiber-aluminum laminates can simultaneously improve the Mode-I and Mode-II fracture toughness of the laminates. Due to the better dispersion of nano-aramid fibers in the epoxy matrix, their toughening performance is better than that of short-aramid fibers in this case.

Summary: Driven by environmental concerns and sustainability issues, researchers have developed novel composite structures in various industries. This study focuses on designing and manufacturing aramid and basalt fiber reinforced polymer hybrid composites as an alternative to carbon fiber reinforced polymer (CFRP) composites. Different fiber ratios and stacking sequences were used to examine their effect on mechanical characteristics. Test results showed that tensile strength was dependent on fiber ratio and sequence, with CFRPs having the highest tensile strength. Impact test results revealed that basalt/aramid fiber hybrid composites had higher energy absorption capability compared to CFRPs. Additionally, increasing basalt fiber ratio increased water absorption capacity, while using aramid fiber in the upper layer decreased ignition loss and increased hardness values. Scanning electron microscopy analysis showed weaker fiber-matrix bonding in hybrid samples compared to CFRPs.

Summary: A novel AZ31B magnesium alloy-based hybrid fiber metal laminates (Mg-FMLs) bonded with Mg-Zn-Al eutectic alloy solder have been prepared using ultrasonic vibration assisted hot pressing technology to enhance interfacial and mechanical properties. The metallurgically-bonded interfaces in the Mg alloy-based hybrid FMLs exhibit higher interlaminar and tensile performance compared to traditional epoxy resin-bonded Mg-FMLs. The synergistic effect from the Mg alloy sheet and CFRP layer contributes to the enhanced tensile properties of the Mg-FMLs.

Summary: This study investigates the shape memory properties of a shape memory epoxy polymer (SMEP) nanocomposite incorporated with a hybrid of multi-walled carbon nanotube (MWCNT) and montmorillonite nanoclay (MMT). The nanocomposites were characterized through cyclic thermomechanical tests and fold-deploy tests. The inclusion of the hybrid nanofiller resulted in a decrease in shape recovery, except for the SMEP nanocomposite. The recovery through thermal and electrically activated methods showed similar profiles, with electrically activated recovery reacting faster. The effect of nanofiller inclusion was more prominent in the thermal activation method. The hybrid filler SMEP nanocomposite with 3 wt.% MMT and 1.0 wt.% MWCNT exhibited better shape memory properties. These findings provide guidance for selecting nanofiller loadings based on performance for specific applications in industries such as aerospace, medical, and automotive.
