A signal segmentation method for CFRP/CFRP stacks drilling-countersinking monitoring
Mechanical Systems and Signal Processing, 2023Carbon-fiber-reinforced plastics (CFRP) stacks are widely used in the aerospace industry owing to their superior mechanical properties and lightweight nature. In this industry, CFRP/CFRP stacks are often drilled and countersunk to create holes for assembly fasteners.

CFRP fuselage structures - postbuckling permitted
Air & Space Europe, 2001CFRP (carbon fibre reinforced plastics) fuselage structures are expected to be realized with future generations of aircraft. Going into the postbuckling regime with these structures requires improved, fast and reliable procedures for analysis and design of stiffened fibre composite panels.

Performance of CFRP-steel joints enhanced with bi-directional CFRP fabric
Construction and Building Materials, 2019Abstract Carbon fiber reinforced polymers (CFRPs) have gained popularity and become recognized as a prominent material for engineering applications in the last few decades owing to their high strength-to- weight ratio, resilience and corrosion resistance. The key concern is the bond between the CFRP and steel elements.

Some effects of moisture on adhesive-bonded CFRP-CFRP joints
Composite Structures, 1986Abstract Investigations have been carried out into the effect of long-term exposure to a hot, humid environment on the strength and mode of failure of CFRP-CFRP joints bonded with structural epoxy adhesives. Strengths of joints have been shown to be reduced both by absorption of moisture and by increased test temperature. There is some evidence that,

Hysteresis behaviour during tensile microstrain and constant amplitude load cycling has been studied with CFRP of approximately 50% fibre volume fraction. This hysteresis is explained in terms of the residual strain in the composite caused by the different thermal expansion coefficients of the fibre and matrix. The energy loss during cyclic deformation
