![]() The flexural modulus of elasticity is determined using Hooke’s law. It is also called young’s modulus and elastic modulus. Materials showing phenomenon tensile strength are:įlexural modulus of elasticity means the stress equation applied to the material along the axis of the sample tested and deformation determined on the same axis. Tensile strength is more important in brittle materials than ductile materials. Talking tensile strength is the maximum stress a plastic material can resist while being stretched before breaking. The flexural strength represents the highest stress experienced by the material in its moment of yield. In that test, a sample rectangular or circular is bent until a fracture occurs. The materials exhibiting excellent hardness are:įlexural strength for any thermoplastics is yielded through the flexure test. While there are several methods to measure hardness in a thermoplastic, the most common method used is known as “ball indentation hardness.” A sphere-shaped metallic ball of standard dimensions is pressed into material with a certain force for a certain amount of time, the residual mark will define the hardness value.Īnother method, “Rockwell Hardness testing,” is also popular for determining hardness.Ĭarbon fiber and glass fiber-filled materials show the highest surface hardness. The thermoplastics with impressive compressive strength are:Įngaging Read – Physical Properties of Plastic Materials | The Complete Guide Hardness However, due to enhancements in creep properties, apparent effects on the load performance are noticeable in the long term rather than the short term (That means patience is the key). Another smart move would be to check the test conditions before comparing compression values from different sources.Ī reliable method to improve or enhance the compression strength of any thermoplastic polymer is to add carbon fiber or glass fiber reinforcements. ![]() ![]() Unrestrained deformation under load isn’t a reliable indicator of success in real-life industrial applications.įor those reasons, the compressive street is not determined at the break but at a defined deformation point (Usually 1,2, or 10%). ![]() One important thing to note is that the compression property at break is not always accurate because ductile materials sample tends to deform without clear breakage. Ĭompression strength is measured by applying a constantly increasing force on cubical or cylindrical samples placed between two plates, thereby measuring elongation and pressure. All the values have been figured out after extensive research, but still consulting with your material supplier is advised for accurate figures.ĭefinition – The meaning of mechanical property is the physical attributes shown by a material upon application of forces.
