Summary: The use of glass fiber-reinforced polymer (GFRP) composites in load-carrying constructions has increased significantly in recent decades. Vinyl ester (VE) resins are being increasingly used in these structural composites, and their long-term environmental exposure consequences need better understanding. Testing the environmental durability of new VE-based GFRPs is time-consuming and costly, and accelerated hydrothermal aging is often used. This paper reviews the literature on hydrothermal aging of VE-based GFRP, focusing on moisture-induced aging, voids, and the fiber-matrix interface on composite mechanical performance.

Summary: Researches have been dedicated to utilizing oil palm shell (OPS) as reinforcing filler in polymer composites and investigating its beneficial effects on enhancing composite properties. The characteristics of OPS, such as mechanical, thermal, water barrier, and biodegradability properties, are discussed. Challenges still exist in exploring the potentials and applications of OPS as a reinforcing filler.

Summary: Carbon fibre reinforced polymer composites have superior properties and are increasingly used in industries like aerospace. Structural health monitoring is necessary due to their complex failure mechanisms. Magnetostrictive materials have been effective in damage detection but need improvement in spatial sensitivity. It is important to demonstrate ease of fabrication, damage detectability, and maintain a good weight-to-cost trade-off.

Summary: The study of failure mechanisms in long fiber reinforced composites is crucial for structural design, particularly in understanding transverse damage mechanisms. Experimental results show that secondary tension does not significantly affect failure stress, while secondary compression may accelerate failure.

Summary: This study examines the effects of thermal ageing fatigue and mechanical ageing fatigue on the mechanical durability and notch sensitivity properties of glass fibre mat unsaturated polyester resin composites and kenaf fibre mat/unsaturated polyester composites. The results show that kenaf fibre mat/unsaturated polyester exhibited a more severe reduction in tensile modulus and un-notched strength compared to glass fibre mat/unsaturated polyester, but displayed lower notch sensitivity after thermal ageing.

Summary: Research on high-strain loading response of high-performance composites found that PEEK composites exhibit higher mechanical performance at high strains compared to epoxy composites. This is due to superior micro-scale shear deformation in PEEK, while epoxy composites experience extensive micro-cracking, coalescence, and fiber-matrix debonding.

Summary: This study introduces a novel 3D printer head for direct-ink-writing that can overcome limitations on printable resins, enabling a wider range of applications in thermoset resins and continuous fibers. The developed printing method can produce composite components with covalently bonded interfaces and comparable mechanical strength to directly-molded samples, and also supports the free-standing 3D printing of UV-curable composites.

Summary: A new fiber-reinforced high-performance lightweight engineered cementitious composite (LWECC) was proposed and thoroughly investigated for its fresh properties, compressive strength, and flexural strength, then calibrated through a printability assessment. The addition of hollow glass microspheres (HGMs) significantly improved the lightweight property of the material but inevitably negated mechanical properties. Superior toughness was observed when the printed filament was perpendicular to the loading direction, resulting in a 63% increase in compressive strength and a 40% increase in flexural strength.

Summary: Research on composite additive manufacturing has increased in recent years. Current commercial equipment can only fabricate carbon fiber composites using limited thermoplastic or rapid curable resins, which cannot meet a wide range of mechanical and durability requirements. In this study, a Rapid Interlayer Curing Assisted (RICA) 3D printing strategy was developed to enable the use of any commercially available thermally curable resin and fibers for 3D printed composites. A robotic system consisting of a specially designed end effector and automated robot arm was created to print continuously reinforced thermally curable thermoset composites.

Summary: This paper investigates the effects of cooling rates on the crystallization behavior, interfacial bonding strength, interlaminar fracture toughness and low-velocity impact performance of carbon fiber reinforced poly(aryl ether ketone) (PAEK) and poly(ether ether ketone) (PEEK) composites. The results show that PAEK has lower crystallinity and smaller crystals compared to PEEK at the same cooling rate. The lower crystallinity and smaller crystals of PAEK contribute to improved matrix ductility and interfacial bonding strength in the composites. Under water cooling conditions, the impact damage area of CF/PAEK is about 71% lower than that of CF/PEEK, while the CAI is about 14% higher.

Summary: This study examined the long-term durability of glass-kenaf fibre reinforced phenolic resin composites when exposed to humid environments or submerged in different pH solutions. The use of microcrystalline cellulose (MCC) as a filler and reinforcement improved the properties of the composites, with higher MCC volume fractions resulting in stronger interfacial bonding, reduced water absorption, and diffusion. The flexural strength of the composites varied depending on the MCC volume fraction and the immersion conditions.

Summary: Advanced fiber reinforced composite materials are important in various engineering applications due to their high specific stiffness and strength, however, the laminate thickness and scaling technique type have significant effects on the flexural response. Thicker laminates exhibit lower strength and strain to failure, but higher bending stiffness. Furthermore, introducing ply clustering has different effects on different configurations.

Summary: The effect of nozzle diameter on the mechanical and geometric quality of 3D printed composite samples was significant. Large nozzle diameters tended to increase mechanical performance and enhance surface roughness, with a reduction in manufacturing costs. In contrast, 3D printed composite samples with small nozzle diameter exhibited higher geometric accuracy.

Summary: The increasing demand for high-quality on-demand products has driven the development of additive manufacturing technologies. Fused filament fabrication (FFF) is one of the most popular AM technologies, but it still cannot compete with traditional manufacturing processes in producing high-quality end-use products. Researchers are developing new advanced filaments infused with nanoparticles, short and continuous fibers to improve mechanical properties and geometric quality features. This study evaluates the impact of fiber addition to PETG filaments on the geometric properties of FFF manufactured parts and finds optimal printing parameters using predictive models.
