“…Specifically, the CFRP tubes were made by T300-Epoxy-Prepreg3k-Woven-Carbon Fibers. The monolayer thickness was approximately 0.2 mm with a nominal ultimate tensile strength of 800 MPa, tensile elasticity modulus of 65 GPa, and density of 1600 kg/m 3 .The weave style is twill. The weight of carbon fiber prepreg is 320 g/m 2 and the content of the resin is 40%.…”

“…[1][2][3][4] The suspension of many racing cars used in Formula SAE consists of a carbon fiber and aluminum alloy bonding structure [5][6][7] as shown in Figure 1. Compared with the traditional repair method for the metal and concrete, such as welding, bolting, and attaching steel plates, the CFRP composite provides higher strength with less weight and higher resistance against the effects of high temperatures and humid environments.…”

According to previous studies, the bond strength between the carbon fiber-reinforced plastics and metals mainly depends on the bond layer between the carbon fiber-reinforced plastic composites and the metal. This article presents the results of the experiments conducted on the tensile bond strength between the carbon fiber-reinforced plastic tubes and aluminum joints. The parameters examined in these experiments include adhesive type, surface roughness of the bonded area, and thickness and length of the bond layer. The results show that the 3M DP-460NS Off-White adhesive was suitable for our experiment. The bonded surfaces of the specimens were smoothened with a P600 sandpaper to achieve higher bond strengths with the adhesive. For the six bond thicknesses tested, a thickness of 0.2 mm was optimal for the tensile experiments. The ultimate tensile force was approximately directly proportional to the bond length.

Öz Çalışmada, ultra yüksek performanslı beton (UYPB) plakalarla güçlendirilmiş eğilme dayanımı yetersiz betonarme kirişlerin davranışı deneysel olarak incelenmiştir. Güçlendirme amacıyla kullanılacak plakaların imalatı için %3 fiber hacmine sahip UYPB kullanılmıştır. Bir tanesi kontrol numunesi olmak üzere, kalınlık değişiminin eğilme davranışı üzerindeki etkilerini gözlemlemek amacıyla 3 farklı kalınlıkta UYPB plaka üretilmiş (30 mm, 50 mm ve 70 mm) ve plakalar betonarme kirişlere uygulanmıştır. Kirişler, dört noktalı eğilme yükleri altında test edilmiştir. UYPB plaka ile güçlendirilmiş numunelerde yük taşıma kapasitesinde %20 ila %58 arasında değişen oranlarda artış elde edilmiştir.

“…Thus, the second and third items of above list are taken into account in steel reinforcement corrosion simulations conducted in the current study. Several experimental investigations have been demonstrated the effectiveness of CFRP retrofit to restore the loss of flexural strength of corrosion damaged reinforced concrete beams [6]. CFRP retrofit is widely used and the effectiveness increased by several modifications [7].…”

Harsh environmental conditions along with aggressive chemical agents are known as one of the main reasons behind damages observed in reinforced concrete members. Corrosion of reinforcement worldwide is one of the leading causes of damages occurred in reinforced concrete over the lifespan. There are many critical energy and transportation infrastructures located on coastal regions exposed to high humidity and chloride content where they are highly prone to reinforcement corrosion. This calls for retrofit methods, which safeguard not only the strength but also the durability of corrosion deteriorated reinforced concrete structures. Carbon fiber polymers considering their mechanical and chemical properties are recognized as one of the main retrofit techniques. In this study, the influence of different levels of corrosion on the structural behavior of reinforced concrete beams is studied. ABAQUS software package is employed to simulate the nonlinear behavior of reinforced concrete beams with tensile reinforcements and stir-ups corrosion degrees of 20% and 40%. The structural behavior of original damaged specimen as well as the same specimen strengthen with carbon fiber reinforced polymer (CFRP) is studied. The purpose of the retrofit is compensate for the loss of shear and flexural capacity of the member due to corrosion. Different variants for the arrangement of CFRP strips are studied and compared. The result of the current research further uncaps the efficiency of fiber polymers to secure strength and durability of corrosion damaged reinforced concrete members.
