“…In terms of weaving pattern, woven E-glass fibre gives better mechanical properties, compared to chopped strand fibre mat. It was reported that woven E-glass fibre has an impact strength of 415 MPa, while chopped strand E-glass fibre presented 189 MPa [ 70 ].…”

“…Fibre content and fibre arrangement affect the impact properties of not only natural fibre composites, but also of glass fibre composites. A study showed that the maximum impact energy absorbed by composites made from one layer of plain-weave glass fibre and two layers of chopped strand glass mats, with 30% fibre content, was 112.105 kJ/m 2 , while that of composites fabricated from two layers of plain-weave glass fibre and one layer of chopped strand glass mat, with 22% fibre content, was 77.141 kJ/m 2 [ 70 ]. Another study reported that a glass wool fibre reinforced epoxy material with a 40% fibre weight gave the highest impact strength value, which was 0.0862 J/m 2 , compared to 30% and 50% glass wool fibre weight composites, which reached 0.0652 and 0.0421 J/m 2 , respectively [ 71 ].…”

Environmental awareness and trends to develop sustainable resources have directed much research attention towards kenaf fibre as an alternative reinforcement in composite manufacturing. Numerous studies have been conducted on kenaf and its hybrid composites. Most studies were conducted on kenaf/glass hybrid composites compared to other kenaf/synthetic hybrid composites. Similar with other materials, mechanical properties were the fundamental knowledge identified by the researcher. Limited studies conducted on other properties have restricted the use of kenaf composites to non-structural applications. To extend the potential of kenaf composites to automotive exterior or other critical applications, studies on impact properties can be a valuable contribution in the material field. This review discusses the mechanical and low velocity impact properties of kenaf/glass hybrid composites reported previously. Percentage loading of fibre, the angle of orientation in woven fibres and the chemical treatment applied to the fibre before compounding are the three major parameters that affect the mechanical and impact properties of the composites. This review provides insights into the mechanical and impact properties of kenaf/glass hybrid composites for future research.

“…This reduces weight, increases strength and stiffness, and generates a finished part with better mechanical properties (Mohd Yuhazri et al, 2010). Vacuum infusion results in a product with high tensile properties with minimal voids in the finished laminates (Heckadka et al, 2015; Herrera et al, 2019). It is a clean process as it requires neither brushes nor rollers, and therefore there is no spattering.…”

Structural design and analysis of a small wind turbine blade using Simple Load Model, FAST-MLife codes, and ANSYS nCode DesignLife

This article presents a structural design and analysis of 11-kW small wind blades. The stress and the fatigue on the blades were computed using Simple Load Model from IEC 61400-2 standard, ANSYS nCode DesignLife, and FAST-MLife codes from the National Renewable Energy Laboratory. Simple Load Model gives good results in terms of stress analysis but overestimates fatigue damage on the blade. High safety factors imposed by the IEC 61400-2 standard, when full mechanical characterization of the blade material cannot be achieved, lead to heavy structures that impact the blade cost. For the same design, full computational analysis of the blade fatigue using FAST-MLife codes and the ANSYS nCode DesignLife revealed that the rotor blades will be safe against fatigue for a design lifetime of 20 years. This study shows that simple and reliable aeroelastic models are still needed for fatigue analysis of small wind blades.

“…The goals of this research is to describe and compare the variation of fibre stacking sequences on quasi-static flexural and creep performance of pGFRP composites. Generally, the pGFRP composite possesses great mechanical strength to resist high load concentration for structural usage [ 61 , 62 ]. Despite many studies focusing on the investigations of FRP composites’ stacking sequences, a comparative study on the effects of stacking sequence on long-term mechanical performance of pGFRP cross arms has still not been fully conducted.…”

Effect of Stacking Sequence on Long-Term Creep Performance of Pultruded GFRP Composites

Pultruded glass-fibre reinforced polymer (pGFRP) composites are classified as lightweight material, which exhibit high strength-to-weight ratio for structural usage. This composite material has been applied as cross-arm members in transmission towers due to its ability in thermal and electrical insulation. However, the influence of the stacking sequence of pGFRP composite on its mechanical performance has not been fully covered in the literature to explain the long-term durability of the current cross-arm designs. The study expected to evaluate five fiber layers with various stacking sequences in terms of quasi-static and creep tests in a four-point bending mode. The creep test was performed for 1440 h (60 days). These composites were fabricated using the pultrusion process in the form of a square hollow structure. Later, it was cut into composite coupons with various sizes depending on the test conducted. The results showed that nine layers with 0°/45°/0°/−45°/0°/−45°/0°/45°/0° had the ultimate flexural strength. This stacking sequence configurations seemed to be optimally manufactured in continuous roving fibre by alternating between 0° and ±45° fiber orientations. Additionally, the S-9 pGFRP composite sample showed that it had a low-creep deflection with high elastic and apparent creep moduli in 1440 h. In terms of strength reduction factor, this configuration was recorded as the highest. The findings showed that the nine layers of pGFRP composites with alternation of 0° and ±45° fiber orientations were highly suitable for structural application at transmission towers for a long-term operation.
