  • The effect of fiber distribution on the flexural and impact properties of T300/BMP316 unidirectional composite laminates was studied through the bending test under three-point loading and using a digital impact test machine. The finite-element analysis was performed to investigate the stress distribution of the deformed model structure with nonuniform fiber distribution. An effect coefficient of fiber distribution R was put forward to characterize the mechanic properties of composite materials. The results show that the flexural and impact properties are greatly affected by the fiber distribution type and the loading direction, and the effect coefficient R can be used to justify the properties of the composite laminates with nonuniform fiber distribution.
