Yokozeki-Higuchi Lab
Machine-translated · View original
The lab pursues structural mechanics for aerospace, with a focus on composite materials.
AboutAbout the lab
Pursuing the essence of structural mechanics
The Yokozeki-Higuchi Lab studies structural mechanics related to aerospace.
Its work centers on the mechanics of components and structures made of composite materials such as carbon fiber reinforced plastic (CFRP), and it tackles fundamental problems in this area.
The lab carries out both numerical analysis, such as the finite element method, and experiments using test specimens.
It also works on structural elements and cryogenic fuel tanks intended for space transportation vehicles and future aircraft, as well as large, flexible space structures that use membranes.
Key terms
- Finite element method
- A method that divides a shape into small elements and uses a computer to calculate how forces are applied and how the shape deforms
- Laminate
- A plate made by stacking many thin fiber-reinforced layers, changing the fiber direction from layer to layer
- Delamination
- Damage in which the layers of a laminate separate from one another. It is one of the weak points of composite materials

ResearchResearch themes
The lab studies structural mechanics related to aerospace, spanning composite materials, aircraft structures, and space structures. Through both numerical analysis and specimen-level experiments, it pursues the essence of structural mechanics problems.
*Illustrative imageDamage and damage tolerance of laminates
The lab investigates, through theory and experiments, the mechanisms of damage such as resin cracking and delamination that tend to occur in laminates made by stacking fiber-reinforced layers, and pursues technologies to suppress such damage.
*Illustrative imageEnhancing composite materials with nanomaterials
The lab creates multifunctional composite materials using nanomaterials such as carbon nanotubes and high-performance resins, evaluates them experimentally, and also works on building models that predict their properties.
*Illustrative imageForming and manufacturing technologies for composites
The lab studies forming methods, forming equipment, and manufacturing processes that allow composite materials to be formed at lower cost, more quickly, and without relying on tacit expertise.
*Illustrative imageTesting and evaluation technologies for composites
The lab studies, through theory and experiments, methods for evaluating the mechanical properties and damage resistance of fibers, resins, and the composite materials and sandwich structures made by combining them.
