Abstract In the curing process of resin matrix composites, the most direct effect of ambient humidity on the curing process of matrix and reinforced fibers is the strength of composite. In order to study the effect of curing humidity (relative humidity) on the mechanical properties of composite laminates, this paper takes T300 3K 40B/1000 (reinforcing fiber) and LY 1564 SPT (matrix resin) as examples to test the mechanical properties of standard samples of carbon fiber composite laminates cured at 30% and 60% ambient humidity respectively, and to test the mechanical properties of the samples by scanning electron microscopy. The fracture area was examined and scanned. The testing and test results show that the tensile and compressive strength of the carbon fiber composites laminates cured at 30% ambient humidity are higher than those of the CFRP laminates cured at 60% ambient humidity, and the interlaminar bonding effect of the carbon fiber composites laminates cured at 30% ambient humidity is better. It provides a reference for technicians to prepare the same materials.
