Description
technical field [0001] The invention relates to a carbon fiber-reinforced epoxy resin-based composite material seawater immersion test device and a test method thereof. Background technique [0002] Carbon fiber-reinforced epoxy resin-based composites are heterogeneous multiphase composites whose macroscopic mechanical properties depend on the material properties and interactions of the mesoscopic components (carbon fiber-reinforced phase, epoxy resin matrix phase, interfacial layer) , and the influence of the resin matrix on the macroscopic mechanical properties of the composite structure is particularly obvious. According to the use environment of carbon fiber reinforced epoxy resin matrix composites in marine engineering, domestic and foreign researches on the structural performance changes in marine environments are mainly divided into two types: sea surface humid heat environment and seawater immersion environment, and the corresponding test piece environment is hot and...
