We have detailed the specific methods and significance of A&E's detection of various types of resin materials and carbon fiber products through various detection methods such as "high-precision moisture determination", "fully automatic refractive index detection", "DHR rheological testing", and "product microstructure analysis" based on the previous two reports.

It is not difficult to see that various high-precision testing tools are like the "quality guardians" of enterprises. In addition to ensuring the excellent quality of products, they also reflect A&E's extraordinary intelligent manufacturing capabilities.

Today, let's enter the A&E's R&D Testing Laboratory for the third time to further understand the high-precision testing tools and methods that safeguard quality.

Differential Scanning Calorimetry Test

Differential Scanning Calorimetry (DSC) is an important test conducted by Zhongshan Rongnan for various resins. This test measures the relationship between the power difference and temperature in the form of heat input to the sample and reference material under program-controlled temperature. Through this test, various thermal effects that occur during the heating process of the resin can be observed, and indicators such as the glass transition temperature (Tg), crystallization temperature (Tc) and crystallinity, melting point stability (Tm), and reaction heat of the resin sample can be measured. And these indicators are extremely important for the quality control process.

Digital impact test

The digital impact test plays a key role in the testing of carbon fiber laminates by A&E. The working principle of this experiment is to release a mechanical pendulum from a certain height and impact the carbon fiber laminate specimen fixed on the test bench. During the impact process, the energy of the pendulum will be transferred to the specimen, causing it to deform until it is destroyed.

Through testing, the ability of carbon fiber laminates to absorb energy, that is, impact toughness, can be accurately obtained. At the same time, the sensor records the force displacement curve during the impact process, allowing us to understand the deformation behavior of the specimen during the impact process, such as whether delamination or fiber fracture occurs.
