Material and structural properties of Marine Rubber Fender

Marine Rubber Fender is generally composed of pure rubber or rubber and metal skeleton, ply. It is molded and vulcanized by the lamination molding method, or molded first and then vulcanized with a vulcanization tank. Marine Rubber Fender is widely used in ports, docks, and ships. Let's take a look at the material properties and structural functions of Marine Rubber Fender

What are the material properties of Marine Rubber Fender?

The base material from which the Marine Rubber Fender is made is rubber. Rubber is a high-molecular compound, and its molecular structure determines that it is a viscoelastic high-damping material with dual characteristics of elasticity and viscosity. The viscoelastic properties of rubber are mainly manifested in two aspects. First of all, the elastic modulus is small and the deformation is large. This is because the chain segments of the macromolecules can move under the action of an external force, that is, the molecules are oriented along the direction of the force, which can make the elastic deformation of the rubber as high as possible. The basic requirement of pier protection for flexible anti-collision devices is that they must have good collision performance with small reaction force and large deformation (displacement). Anti-collision devices made of Marine Rubber Fender have exactly this characteristic. The second is that deformation takes time. The simultaneous occurrence of elastic deformation and plastic deformation is a characteristic of the deformation behavior of polymer materials, which is called viscoelasticity, and the viscoelastic behavior depends on time. Deformation lags behind stress are called hysteresis, and hysteresis causes part of the elastic energy to be converted into heat energy and lost. The rubber with viscoelastic properties is used to make the pier anti-collision equipment - Marine Rubber Fender, because of its viscosity, it can consume part of the impact energy of the ship, and the impact process takes a long time, greatly reducing the impact force.

What are the structure and performance of Marine Rubber Fender?

Marine Rubber Fender is divided into cylindrical type (CY), semicircular type (D), super arch type (A, SA), and super drum type (sc) according to the structure. The product specifications of each structure have been serialized. For example, a Cylinderical fender has 17 specification grades from CYl50×L to CYl600×L. D-type, A-type (V-type), SA-type, and SC-type each form a series of related specifications. The compression deformation of the Marine Rubber Fender of each structure is more than 50% of the main body. This structural feature proves that it fully meets the practical requirements of "small reaction force and large deformation" of the pier anti-collision device.
