Test Background
Fiber-reinforced plastic tensile test can measure the tensile stress, tensile elastic modulus, Poisson's ratio, elongation at break and draw the stress-strain curve of fiber-reinforced plastics.
Zhongke Testing Reliability Experiment Center has reliability testing capabilities for various fiber-reinforced plastics and provides professional tensile 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
A static tensile load is applied at a constant speed along the axial direction of the specimen until the specimen breaks or reaches a predetermined elongation. During the entire process, the load applied to the specimen and the elongation of the specimen are measured to determine the tensile stress (tensile yield stress, tensile fracture stress or tensile strength), tensile elastic modulus, Poisson's ratio, elongation at break and draw the stress-strain curve, etc.
