Bismaleimide (BMI) resins are used in carbon fiber reinforced composites for high-temperature applications. Conventional BMI resins require high cure and post-cure processing temperatures, which limit fabrication methods and contribute to residual st

Pitch-based carbon fiber reinforced epoxy composites are used in specialized applications for their high-modulus and thermal conductivity; however, little data on their fatigue performance are available in the open literature. In this study, fatigue

Hybrid steel-composite gears, which combine steel teeth with a fiber-reinforced polymer composite core, are a rapidly emerging technology for weight reduction in aerospace drivetrain systems. However, power transmission gears—and especially the req

Tensile quasi-static and fatigue behaviors of out-of-autoclave, quasi-isotropic, E-glass/epoxy composites with woven and stitched fiber architectures are compared. Some specimens were cyclically loaded to failure, while others were tested for residua

This paper characterizes the variation in electromagnetic properties of single-ply unidirectional carbon-fiber-reinforced-polymer (CFRP) laminas between samples fabricated using the same material. The variation is referred to as the electromagnetic-p

Triaxially braided fabrics with equal volume fractions of fibers oriented at 60- degree intervals allow for the quick and easy hand-layup of quasi-isotropic (QI) composite laminates, in comparison to unidirectional tape and biaxial-woven fiber archit

The compression modulus and compression strength of a proprietary ultra-high modulus carbon/epoxy composite are experimentally determined using SACMA SRM 1R-94 and ASTM D6641 for laminates with stacking sequences of [(0/ ± 60)s]2 and [(+60/0/−60)s
