Intermediate Products Efficient mixing and deaeration of resin used for CFRP base materials

Technical Classification:
[ Intermediate Products ]
[ Equipment / Facilities ]
[ Centrifugal force ] [ Deaeration ] [ Mixing ] [ Reduction in operation time ] [ Reproducibility ]

Point of the Proposed Technology

・It can improve productivity and reproducibility more significantly by using rotation/revolution type mixing and deaeration machine than by hand or propeller mixing when mixing resin as a base material with hardening material etc.


・Operation time: 1/10 (compared with hand mixing)
・Consistent and highly reproducible processing regardless of operators

Conventional Technology

Example of application to materials such as resin

・Hand mixing takes long operation time. Mixing high-viscosity materials is a large burden for operators.
・Among operators, processing state is not consistent.
・Foam will be produced through hand mixing and propeller mixing.

New Technology

Example of application to materials such as resin

・Cleaning is not required for every lot with no contamination risk.
・Both rotation and revolution motors are controlled by inverter, so it is possible to perform highly reproducible mixing deaeration.
・Saves significantly operation time.

Technology Deployment and Cooperation

Development Stage
Commercialization Completed (already delivered: yes)
Intellectual Property Right
Joint Researchers (their role)
Example of Application
・Mixing of two-liquid type sealant and adhesive for aeroplanes.
・Mixing and deaeration of impregnated resin materials of carbon fiber.
Technical Problems
・If processing continues for a long time, the temperature of raw materials and the device will increase.
・It can sometimes be difficult to deaerate foam from materials with high-viscosity.
Collaborator needed to Improve
・Companies which want to mix and deaerate raw materials and can evaluate its state after processing.
