Abstract

The complex and hollow nature of 3D spacer fabrics require novel approaches to achieve efficient transfer of resin to the structure with a uniform fashion. In this work, a custom-built spray system is designed and built to achive an effective wetting of 3D I-beam fabrics for a high-quality composite manufacturing of a spacer structure. The spray-wetted 3D I-beam composites were manufactured with a custom-designed 3D molding for 600 TEX glass fiber and epoxy resin. Since achieving high-quality composites is essential to accomplish the required mechanical characteristics, the 3D I-beam composites fabricated with vacuum infused process were also compared with spray-wetted and molded specimens. The quality of both specimens was evaluated by optical microscopy images for void content and the results clearly demonstrated a higher void content of 5, 65 times more for spray wetted specimens compared to produced ones with vacuum infusion. The results of the three-point bending tests were in line with the calculated void content. 3-point bending results of vacuum infused 3D composites were measured as 13, 3 MPa where the spray-wetted 3D composites presented as 11, 6 MPa.
