“…Polymer composite materials are very important in various products and applications in some sectors, such as the automotive industry, mechanical industry [33,34], marine industry, aerospace industry [35,36], civil industry, and the infrastructure industry [37,38]. In terms of ensuring environmentally friendly and sustainable technology growth, some industries have adopted natural polymeric composite materials in their applications [39,40]. Table 1 shows several fiber-reinforced polymer composite applications and properties in different areas.…”

Nowadays, pultruded glass fiber-reinforced polymer composite (PGFRPC) structures have been used widely for cross-arms in high transmission towers. These composite structures have replaced cross-arms of conventional materials like wood due to several factors, such as better strength, superior resistance to environmental degradation, reduced weight, and comparatively cheaper maintenance. However, lately, several performance failures have been found on existing cross-arm members, caused by moisture, temperature changes in the atmosphere, and other environmental factors, which may lead to a complete failure or reduced service life. As a potential solution for this problem, enhancing PGFRPC with honeycomb-filled composite structures will become a possible alternative that can sustain a longer service life compared to that of existing cross-arms. This is due to the new composite structures’ superior performance under mechanical duress in providing better stiffness, excellence in flexural characteristics, good energy absorption, and increased load-carrying capacity. Although there has been a lack of previous research done on the enhancement of existing composite cross-arms in applications for high transmission towers, several studies on the enhancement of hollow beams and tubes have been done. This paper provides a state-of-the-art review study on the mechanical efficiency of both PGFRPC structures and honeycomb-filled composite sandwich structures in experimental and analytical terms.

“…The results indicated that all the proposed hood designs showed a significant improvement in injury mitigation. Shojaeefard et al [18] developed a new finite element model to compare pedestrian friendliness of four hoods with four different inner parts including hemispherical, conical, wavy and the combination of wavy-conical structures to the original hood and the engine parts were modeled as rigid according to the EEVC WG17 regulation requirements. They showed that their designs had rigorously improved the pedestrian safety with respect to the original one because of involvement of the entire structure in energy absorption.…”

Abstract. Skull stiffness of children is of great significance to protect brain tissues during traffic accidents. In this paper, the effects of skull stiffness on traumatic brain injury (TBI) are investigated by using a validated 6-year-old child head finite element (FE) model according to Chinese standard GB/T 24550-2009 Results showed that the HIC value, intracranial pressure, Von Mises stress and shear strain of brain tissue increased with the decrease of skull stiffness during the impact of FE model with engine hood. Therefore, the injury risk of the child head decreases with the increase of skull stiffness. And the skull with higher stiffness can provide a better protection for brain tissues during traffic accidents.
