Mechanical properties describe the material’s reaction to an applied force, such as tension, compression, impact, etc. Introduction to Mechanical Properties: General Considerations 2. Particulate fillers like talc or ground calcium carbonate generally increase modulus, while plasticizers decrease modulus and enhance flexibility. Products and packaging undergo continual revision and improvement, with most companies constantly striving to use less material, simplify their manufacturing processes, and make their products more user friendly. All Rights Reserved BNP Media. These standards equalize the dimensions of the test specimen, specifications of the measurement devices, rate of testing, and means of data analysis so that results can be compared across laboratories. From the series of testing the behavior of wood plastic composite (WPCs) will be observe such as tensile strength, yield point and Modulus of Elasticity (MOE). Study on Mechanical Properties of Concrete Using Plastic Waste as an Aggregate | Jaivignesh, B; Sofi, A | download | BookSC. It is measured by applying an increasing force on cylindrical or cubical specimens held between two plates, while measuring both pressure and elongation. To make material properties transparent and accessible to their end users, plastics manufacturers generally provide data sheets describing the mechanical properties of the plastic being purchased. Plastic Testing Laboratory and Analysis Service. Hydrolysis resistance 3. For example, tensile properties of plastics such as plastic tensile strength and rigidity can be determined according to DIN EN ISO 527 by briefly applying load in one direction with a tensile test. A wide variety of mechanical properties of plastics options are available to you, such as 3 … The purpose of this study was to provide baseline date information for tailoring mat-forming techniques, and performance standards to industrial products. A small rectangular rod is struck by a pendulum at high speed and the energy absorbed while breaking the specimen is measured; the higher the value, the better the impact resistance. Modulus of elasticity is also known as Elastic Modulus or Young’s Modulus and is defined as the measurement of a material’s resistance to elastic deformation. Typical high impact strength plastics are: While surface hardness can be measured in many different ways, one of the most common methods used to test thermoplastics is called “ball indentation hardness”.A metallic sphere of standard dimensions is pressed into the material with a defined force and for a defined time, the residual mark in the material defines the hardness value. For some plastics, UTS is clearly represented by a significant peak in the stress-strain curve. This stress-strain curve shows several important mechanical properties. In order to do a through research, a few testing will be done on the panel itself such as Tensile testing, Flexural testing and Impact testing in order to observe its mechanical properties. This page describes the mechanical properties of materials that are relevant to the design and analysis of mechanical systems. Lastly, strain is measured either by the movement of the testing system’s crosshead or by a strain device such as an extensometer compared to the initial length. ABS shows excellent mechanical properties i.e. Figure 1 shows a typical tensile stress-strain curve of non-reinforced nylon in a dry state and at equilibrium water absorption. This information allows users to directly and reliably compare the physical properties of different engineering materials. Products.
