Improvement on cost-performance ratio of fiberglass/carbon fiber hybrid composite

Abstract

Fiberglass composite (FG) is widely used as a metal substitute in general applications due to its corrosion and chemical resistance, relatively high strength, and low cost. Still, the FG is deficient in performance and relatively heavy for airframes. Carbon fiber composite (CF) is utilized instead as it has greater performance and lower weight. However, the CF is brittle and expensive. Thus, in this work, we combine FG and CF into two types of hybrid composites to achieve a cost-effective solution with greater or comparable mechanical properties to those of CF. The first one uses FG as core and CF as skins (SWFG). The second one uses CF as core and FG as skins (SWCF). Their mechanical properties and cost-performance ratios (CPR) are compared. The results show that the mechanical properties of the SWFG composite, especially the modulus of elasticity, are considerably improved over the FG and nearly match those of the CF. Also, the SWFG has better CPR regarding tensile properties and flexural modulus than the SWCF and the CF. The SWFG shows promising potential as an alternative to the CF due to its comparable performance and almost 40% lower cost than the CF.

A Multi-Objective Optimization of Neural Networks for Predicting the Physical Properties of Textile Polymer Composite Materials

“… Fiberglass-reinforced plastic, commonly known as fiberglass [ 75 ], is a composite material composed of fine glass fibers embedded in a polymer matrix, typically epoxy or polyester resin [ 76 ]. This material exhibits a high strength-to-weight ratio [ 77 ], excellent corrosion resistance [ 78 , 79 ], and dimensional stability [ 80 ], making it suitable for applications requiring durability and structural integrity [ 81 ]. We considered types such as T-10 [ 82 ], T-13 [ 83 ], T-11 [ 84 ], T-SU 8/3(VMP)-78 [ 85 ], and T-25 [ 86 ].…”

“…For years, UAVs have played an important role in national security operations, in the military field, including in the prevention of terrorist threats and humanitarian assistance and disaster relief, due to their superior functionality to the people. Many countries and government agencies have invested huge sums/billions to improve their performance (Poopakdee and Thammawichai, 2021). Drones are definitely the most important technology that can be used in anti-terrorism operations being equipped with electro-optical cameras that can track both stationary / moving targets.…”

Comparative study on three body abrasive wear behaviour of natural compliant thermoplastic composite under dry and lubricated conditions

“…Composites can be a great replacement to metals and alloys in many applications due to their unique combination of properties. [1][2][3][4] Composites are materials made up of multiple components that work together to create a material with superior properties. Some examples of composites that are being used as replacements for metals and alloys include carbon fiber reinforced polymer (CFRP) composites, glass fiber reinforced polymer (GFRP) composites, and ceramic-matrix composites (CMCs).…”
