| Abstract Scope |
Carbon nanotubes (CNTs) are emerging as a potential material to replace or augment carbon fiber-reinforced polymers (CFRPs) and are the next generation for aerospace structural composite material applications. This work incorporates a layer of two-dimensional randomly oriented CNT materials into the neutral plane of unidirectional carbon fiber composites to evaluate the manufacturability and specimen quality of scalable Hybrid CNT/CFRPs. Two types of scalable floating catalyst chemical vapor deposition (FCCVD) derived CNT materials are used: CNT sock, an aerogel-like material of 0.57 g/m2 in aerial density, and CNT sheet, which is many layers of sock has an aerial density of 8.09 g/m2. IM7 carbon fiber prepregs are used with CYCOM® 5250-4 bismaleimide and CYCOM® 977-3 toughened epoxy resins in an autoclave manufacturing process. Laminate quality is investigated with an ultrasonic C-scan. The 977-3 Sheet laminate achieves a longitudinal flexural modulus of 135.5 ± 7.6 GPa, while the 5250-4 Sheet laminate achieves a transverse flexural strength of 150.0 ± 10.0 MPa, which is a 25% increase beyond the control. Both resin systems and CNT material combinations are nearly identical in short beam shear strength, with the 5250-4 Sock laminate at 114.1 ± 1.51 MPa. Notably, the CNT materials are more likely to cause crack deflection in the specimens. This study shows that quality aerospace-grade hybrid composites can be manufactured using scalable CNT materials with traditional industry-standard processes without compromising the mechanical properties of the carbon fibers. |
