Information
Aircrafts in recent years have been designed to be lighter in order to improve fuel efficiency and reduce carbon dioxide emissions.
One of the most effective ways to achieve this is to replace conventional aluminum alloys with carbon fiber–reinforced plastic (CFRP) as the airframe materials.
However, CFRP has lower electrical conductivity than metal, so it is more susceptible to damage when subjected to lightning currents.
Currently, a metal mesh is attached to the fuselage to prevent such damage. However, this is time–consuming and costly.
A new coating technique called the cold spray technique is attracting attention as an alternative to metal mesh.
This technique forms a coating by colliding particles of several tens of microns with CFRP at high speed without melting them.
The deposition rate is short and no special skills are required,
but it has been difficult to deposit metal particles on a heterogeneous material such as CFRP.
In this forum, we will explain the basics of CFRP, such as what it is and how it is applied,
the basics and applications of the cold spray technique, which can deposit metals to prevent lightning currents,
as well as how to treat the particles when depositing metal particles on different materials such as
CFRP and how they can be applied to aircraft materials after treatment.
The application of metallic particles to aircraft materials after treatment will also be explained.
This event will be held in Japanese.
