Abstract: Fiber-reinforced polymer composites (FRPCs) using continuous fibers and thermosetting polymers are widely used because of the excellent specific mechanical properties, thermal stability, and chemical resistance. The development of cost-effective and mold-free manufacturing processes for FRPCs with manufacturing flexibility and 3D structure has received extensive research attention. Here, we report a UV-assisted 3D formation approach to coat thin UV resin layers on both sides of the raw material (Fiber tow, prepreg) to enable a fast curing on the interface to achieve good interfacial bonding to form a solid three-dimensional (3D) object. The continuous fiber/thermoset epoxy composites made with prepreg (unidirectional carbon fabric) and UV resin serving as the layer binder by this route were investigated to demonstrate the feasibility and generality of the proposed technique. The mechanical testing results showed the manufactured composite exhibited a tensile strength of 1075.27 MPa and modulus of 45.24 MPa; a flexural strength of 1209.50 MPa and modulus of 68.01 GPa; and interlaminar strength of 37.17 MPa.
