Study the Biaxial creep of continuous polymer fiber composites

Creep is the slow continuous change in the dimensions of the engineering piece during the service.  The study of the creep is one of the very important things in order to avoid the disasters that occur as a result of changing the dimensions.  Since we are studying creep and its effect on engineering parts in various fields in which polymer or composite materials are used, and among these areas is the use of polymers and composite materials in dams, then we must choose polymeric materials carefully so that these materials must have special properties in terms of strength and rigidity.  In order to meet the required requirements in terms of properties, we chose high-density polyethylene because it has several properties, including its high degree of urgency as well as high inter molecular force, but this material alone does not meet all requirements because the polymer alone is not considered a successful material.  High-density carbon fiber and we got a composite material with excellent properties that are much better than high-density polyethylene alone. &nbsp
