Synthetic materials such as Carbon, Kevlar, and Glass fibers are extensively utilized in various industries due to their superior characteristics including high stiffness, great strength, low den-sity, and high wear resistance, these advantages contributed to making them widespread in ap-plications like; aerospace, automobile, civil and electronics. This research is carried out to enhance the creep compliance of epoxy composite material by considering two types of fibers as reinforcement. A composite material is produced by combining two fibers, Kevlar fiber mixed with sika epoxy resin, along with Carbon fiber also mixed with sika epoxy resin using a Hand-Layup process. Experiments and numerical modeling are examined to offer a comprehensive understanding creep behavior of epoxy composite material in different weight ratios. Burger and Prony models are used to represent stress relaxation and creep strain of Visco-elastic material. According to the results, sika epoxy resin reinforced with Kevlar and Carbon fibers exhibits enhancement in the mechanical properties compared with pure epoxy. The use of Kev-lar/Sika epoxy composite results in higher creep compliance and modulus of elasticity compared with Carbon/Sika epoxy composite.

This study was focused on investigating the influence of fiber-to-matrix weight ratios on the creep behavior of a composite material made from E-glass fiber and polyester resin. The aim was to assess the practical applicability of the composites for aircraft and vehicle structural parts by checking creep strength. The test specimens were prepared using the hand layup method, combining E-glass fiber and polyester resin. Three different fiber-to-matrix weight ratios (65/35, 55/45, and 35/65) were selected and the test specimens were manufactured according to the ASTM D2990 standard. The tests were conducted on each weight ratio using creep loads of 20, 30, and 40 N., and finite element analysis (FEA) was performed to substantiate the experimental results. Based on the experimental and simulation results, it was observed that the composite with a fiber weight ratio of 65/35 has 62.43 Mpa stress and 7.59 mm deformation. This exhibited favorable creep behavior and higher deformation resistance compared to the other compositions. The finite element analysis results were in good agreement with the experimental findings. This suggests that this weight composition could be preferred for vehicle structural parts. The agreement between the experimental and finite element analysis results further validates the practical applicability of the composite material.

“…Several attempts had been made throughout the past decades to evaluate the potential of chicken feathers as reinforcements in applications of composite materials. Abed et al [5] investigate the creep behaviour of an epoxy composite reinforced with Yttrium Oxide Powder at different weight ratios. Each volume ratio was subjected to five loads at a steady temperature.…”

The use of composite materials has expanded in industrial applications around the world, reinforcing composites with waste materials like (chicken feather) is one of the effective ways to solve environmental concerns compared to traditional methods, as it is considered one of the renewable and inexpensive methods in addition to its presence in abundance. The main added features of composite materials over classic materials are the light-weight. This paper investigates the effect of immersion media for a polyester composite reinforced with chicken feather fillers to enhance the creep characteristic. The composite was manufactured using a hand-layup process. The samples were produced by varying the weight ratios of fiber loading (0 %, 0.2 %, 0.4 %, 0.6 % and 0.8 %) and immersed in three different media (KCl (salt media), NaOH (alkali media) and HNO3 (acid media)). The creep samples were tested according to ASTM standards. The results show that chicken feather–reinforced composites immersed in various media have probable applications because of their superior mechanical properties over non-reinforced composites.
