Test Background
Fiber-reinforced plastic creep test can measure the tensile creep performance, compression creep performance, bending creep performance and creep rupture stress of fiber-reinforced plastics under specified conditions.
Zhongke Testing Reliability Experiment Center has reliability testing capabilities for various fiber-reinforced plastics and provides professional creep testing services for fiber-reinforced plastics.
Scope of tests
Commonly used fiber-reinforced plastics include polypropylene (PP), polyethylene (PE), polyester (PET) and other high-molecular polymers and high-purity natural wood, as well as some man-made fibers (cellulose fibers), glass-reinforced resins and metal fibers.
It can be divided into three categories according to its molding methods: thermoplastic resin, thermosetting resin, and polycarbonate.
Test method
Under certain temperature and humidity conditions, the set tensile, compression or bending stress is stably applied to the sample and maintained until the specified test end point is reached or the sample fails.
During the entire process, the deformation of the specimen is continuously measured to determine the creep modulus and plot the creep strain-time curve, creep modulus-time curve, creep rupture curve or isochronous stress-strain curve.
