Test Background
Glass fiber reinforced plastic, also known as fiberglass, is a material composed of glass fiber and one or several thermosetting or thermoplastic resins. It is widely used in urban sculptures, arts and crafts shapes, fast food tables and chairs, motorcycle parts, fiberglass flower pots, safety helmets, high-end amusement equipment, household appliance casings, etc.
The aging test of glass fiber reinforced plastics can determine the effects of glass fiber reinforced plastics on their appearance, physical or mechanical properties when exposed to the atmosphere without external stress, under constant or alternating heat and humidity conditions, and under water media conditions.
Zhongke Testing Reliability Experiment Center has the capability of reliability testing of various fiber composite materials and provides professional aging testing services for glass fiber reinforced plastics.
Scope of tests
is divided into glass fiber reinforced composite plastic (GFRP), carbon fiber reinforced composite plastic (CFRP), boron fiber reinforced composite plastic, etc. according to the different fibers used.
Test method
1. Damp heat test: Under constant or alternating damp heat conditions, the changes in appearance, physical or mechanical properties of the sample are measured after a specified damp heat test cycle. It is divided into constant damp heat test and alternating damp heat test.
2. Water resistance test: After the immersed parts are immersed in water media for a specified test immersion period, the changes in their appearance, physical or mechanical properties are measured.
3. Accelerated water resistance test: The sample is immersed in water at a specified temperature for a specified test immersion period, and the changes in its appearance, physical or mechanical properties are measured.
Test standard:
GB/T 2573-2008 Test method for aging properties of glass fiber reinforced plastics
GB/T 1446 General principles for performance test methods of fiber reinforced plastics
GB/T 1449 Test method for bending properties of fiber reinforced plastics
