In view of the influence of microvascular on the mechanical properties of laminates, the tensile properties of laminates with varying diameter microvascular channels were studied. Tensile strength and stiffness of laminates with varying diameter microvascular channels were determined by experimental measurements. A refined finite element model of laminates containing microvascular channels was established, which considered the effects of resin-rich area, fiber bending, and fiber volume fraction change, and the tensile properties of laminates containing microvascular channels were analyzed and the results were verified by the experimental results. On this basis, the effects of microvascular channel orientation and diameter were investigated. The results show that when the microvascular channel is laid in a vertical ply direction, it decreases the longitudinal tensile strength of the unidirectional laminate, but the stiffness is basically unaffected. The larger the diameter of the microvascular channel, the greater the reduction of tensile strength. The structural strength of the laminate containing microvascular channels with diameters of 0.255 mm and 0.4 mm is reduced by 21.9% and 39.9%, respectively, when compared to the tensile properties of the laminate without the channels; however, its stiffness changes less than 1.4%.The damage process of laminate also changes with the microvascular channel diameter.
