| الوصف: | Sandwich panels composed of two skins separated by a core in the middle have attracted many researchers to develop lightweight structural materials that can be assembled quickly. This article will discuss the flexural strength of each skin, core, and sandwich panel. The composite sandwich skin is made of Recycled Carbon Fibre (RCF)/unsaturated polyester with a thickness of 2 mm. The face has a low density of 1.6 g/cm3 and is more economical because of the recycled carbon fibre. RCF was taken through the solvolysis process by degrading the resin on the carbon fibre. Polyurethane reinforced with five layers of Cotton Mesh Fabric (CMF) is used as the core with various thicknesses of 50 mm, 75 mm, and 100 mm. CMF reinforcement made of polyester has a density of 0.03 g/cm3. The results showed that increasing the fiber content by 40% raised the RCF/unsaturated polyester skin’s bending strength to 220.7 MPa. Due to the higher fibre content, stress can be spread evenly. In addition, the flexural strength of the polyurethane core increases up to 2.1 MPa with the addition of CMF. Sandwiches with a 50 mm core have a flexural strength of 59.07 MPa. It is higher than the 75 mm and 100 mm thicknesses. It is due to an increase in the moment of inertia and stiffness of the composite material. This lightweight and strong sandwich composite can be used as an earthquake-resistant wall panel. |
