출시 시간: 2023-11-15
현대엔지니어링 분야에서는, 유리섬유 강화 복합재료는 다양한 구조에 널리 사용됩니다., 하지만 시간이 지나면서, these materials may be affected by the natural environment and aging. In order to better understand and predict this aging process, researchers have adopted various aging test methods. This paper introduces the aging test methods of glass fiber reinforced composites, including atmospheric exposure test, accelerated atmospheric exposure test and artificial accelerated aging test.

1. Atmospheric exposure test methods

Atmospheric exposure test is a method of approaching the actual use environment of materials, especially for the weatherability of materials. The selection of the test site should represent the different climatic environments of the tested material under different conditions of use. The results showed that the exposure tests conducted in different climate regions showed that the humid and subhumid climate regions had the fastest aging rate and the most chances of mildew growth. The data of this test method can be used as the comparison basis of other artificial aging tests, which has reliability and authenticity.

2. Accelerated atmospheric exposure test method

In order to overcome the shortcomings of the long period of natural atmospheric exposure test, the researchers introduced the accelerated atmospheric exposure test method. The test can be carried out in natural environment by using the exposure frame with special structure, and the results have a good correlation with the natural atmospheric exposure test. Despite the high equipment investment, it improves the problem of long conventional aging cycle and shortens the test cycle.

3. Artificial accelerated aging test method

The artificial accelerated aging test method is carried out in the laboratory using various aging chambers. 그 중, boiling water frying method, artificial climate test, wet heat aging test, salt spray corrosion test and mold test are commonly used methods. These tests can simulate and strengthen the aging factors of materials under different environmental conditions, and obtain test results quickly. 특히, the wet heat aging test takes into account the influence of humidity and temperature, which is suitable for some heterogeneous materials.
