The bi-composite transition joint [PDF]

, 1972
The application of advanced composite materials to high performance structure frequently results in the desire to fabricate a structure from more than one composite system in order to tailor the composite material capabilities to the design requirements.

Psychological Safety Among Interprofessional Pediatric Oncology Teams in Germany: A Nationwide Survey

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Psychological safety (PS) is essential for teamwork, communication, and patient safety in complex healthcare environments. In pediatric oncology, interprofessional collaboration occurs under high emotional and organizational demands. Low PS may increase stress, burnout, and adverse events.

A CAI study on transition zones of conventional and Double-Double laminates

Composites Part C: Open Access
Laminate-thickness tapering opportunities of Double-Double (DD) laminates are unique, compared to conventional laminates (denoted as Quad) in aerospace, which are typically composed of 0°, 45°, −45°, 90°plies.

Holistic determination of physical fracture toughness values and numerical parameters for delamination analysis considering multidirectional-interfaces

Composites Part C: Open Access, 2022
Delaminations are a concern for the structural integrity of fibre composite structures. The decisive material parameter for delaminations is fracture toughness. Structures usually have a multidirectional ply stacking.
