| Abstract Scope |
Additive manufacturing (AM) of composite tooling has substantial advantages over traditional tooling techniques for out-of-autoclave processes due to large reductions in tooling cost and fabrication time. Thus, 3D printed tooling has potential for diverse commercial uses in industries including aerospace, automotive, and defense. However, low durability of 3D printed thermoplastic (TP) tooling from inexpensive materials limits performance, while the high surface roughness of as-printed tooling necessitates extensive machining. Therefore, we propose a laser co-bonding AM method to bond durable continuous carbon fiber reinforced thermoset (TS) coatings on 3D printed TP tooling. By combining resin infusion and consolidation during laser co-bonding, excellent surface finishes were produced thereby reducing or eliminating the need for machining, while simultaneously reducing voids at the interphase region. Lap shear testing revealed excellent bond strength between the TP-TS materials. Thermogravimetric analysis and differential scanning calorimetry of the TS composites combined with numerical simulations guided process parameter selection. |
