In these applications, it is important to understand the mechanical strength properties of these plastics. Included in these methods are accuracy specifications for the test frame and test accessories.
Dependent on the gauge length of the specimen used, this relative accuracy requires the following absolute accuracy:. In particular, the SIESA series enable automated extensometer arm attachment and removal, increasing testing efficiency and minimizing differences between operators.
Plastics come in a wide variety of types and strengths, depending on the ingredients, mixtures, and composition used. For instance, in structural materials, plastics can be pliable or rigid. There are also many types of engineering plastics and plastics used in composite materials, such as carbon fiber reinforced plastics CFRP. Avoid working under conditions that would create a large build-up of heat in the specimen the use of a coolant is recommended.
Cut out rectangular strips of the required length and width for the tabs. It is desirable that the adhesive used be flexible in nature. The adhesive should preferably have a shear strength greater than 30 MPa. It is recommended that a film adhesive with a thin carrier be used.
