Abstract: To explore the influence of the microstructure of reinforcement fabric on the mechanical properties of curved composite, the basalt fabrics with different organizational structures including plain, twill, satin, and weft-free structure were immersed in a mixed solution of epoxy resin and curing agent, to prepare a series of curved composite materials by pressure composite molding in a special mold. The bending strength and flexural modulus of the curved composites were measured by a three-point bending test method. The impact properties, bursting strength and failure mechanism of the curved composites were studied. The results indicated that the basalt basalt-fiber-reinforced curved composites with plain weave reinforcement have optimum bending performance, but those with a satin structure have optimum impact optimum performance and similar the bending strength. On the other hand, the curved composites with the satin structure have slightly lower bursting strength than those with a twill structure.
