Abstract The compressive fracture aspect for the thick quasi-isotropic carbon fiber reinforced plastic (CFRP) laminates was investigated using a high-speed camera to clarify the progress of the brooming fracture. The compressive fracture types of the laminates could be classified into two groups, i.e., the fractures initiating from the innermost 0 ∘ ply and those initiating from the fixed sections of the specimen. The standard deviation of the compressive strength for the innermost 0 ∘ ply-initi...

Measurement of the elastic moduli of carbon fiber-reinforced plastics (CFRP) can be difficult owing to the anisotropic and viscoelastic characteristics of CFRP. In this study, a technique based on ...

Abstract The shear and tensile strengths of carbon fiber-reinforced thermoplastic (CFRTP) laminate joints by ultrasonic welding were investigated by lap shear tests (LSTs) and cross tensile tests (CTTs). The adherends were the cross-ply and the twill woven CFRTP laminates, and the flat energy director (FED) was used to clarify its effectiveness. A modified jig and testing method for CTTs were newly proposed. In each test, the strengths were calculated in two ways: by indicators of “welding effic...
