This state - of - the - art tester is primarily designed for prefabricated damage testing of composite plates. It strictly adheres to industry - recognized standards such as ASTM D 7136/D 7136M, which details the standard test method for measuring the damage resistance of a fiber - reinforced polymer matrix composite to a drop - weight impact event, and GB/T21239 for the test method of compression performance of fiber - reinforced plastic laminates after impact, as well as GB/T2611 for general technical requirements for testing machines.
Equipped with impact force value sensors, an advanced test system, and high - speed data acquisition cards, the HST - DIT302E 300J can accurately measure the load and deformation transient values during the fracture process of the impacted sample. It precisely captures crucial data including impact absorption work, the force - displacement - energy curve of the impact process, and characteristic points on the curve like slope discontinuity force F1, maximum contact force Fm, maximum force energy Wm, total impact energy Wt, and corresponding displacement.
This wealth of data enables in - depth analysis of the sample's impact process, effectively reflecting the material's ability to resist dynamic impact loads, the force and deformation characteristics of the sample under impact, and facilitating dynamic fracture toughness analysis of the material at high strain rates.
With the HST - DIT302E 300J composite plate drop hammer impact tester, HST Group continues to set new benchmarks in providing reliable and accurate testing solutions for composite materials, ensuring product quality and safety in the aerospace and automotive sectors.
