Objective:
This project is organized for investigation of design methodology for composite Type 4 hydrogen tank, which is manufactured by multi-filament winding method. Results of the project will be utilized for development of adequate hydrogen tank from the view point both of reliability and total cost.

Results in 2015 FY:
The research is focused on basic investigation of finite element simulation and manufacturing technology.

(1) Investigation of innovative design methodology based on meso-scale simulation (The University of Tokyo)
We have developed FrontCOMP simulation system to evaluate strength reliability of carbon fiber-reinforced plastic hydrogen tank. The system is improved to handle multi-filament winding method. We can reveal an advantage of the multi-filament winding method from the view point of low stress concentration in fiber bundle.

(2) Development of Multi-filament Winding Technology (Murata Machinery Limited)
We have made sample tanks with 2 ways of filament winding methods, and evaluated them. As a result, we have made it clear that multi-filament winding method is more flexible in the tank design than single-filament winding method. And we have made the control parameter to achieve the tank design.

(3) Development of Evaluation Method of Manufacturing Error of Multi-filament Winding Tank (Teijin Limited)
We have tried to develop ‘thin-layer filament winding evaluation method’ for the identification of the advantage of multi-filament winding, which is making thin-layer single-filament winding or multi-filament winding on type-3 liners (5L class) and, then evaluating the burst pressure of the cylinders. As a result, we found that it is important to understand and control carbon fiber adhesions and/or position change of wound carbon fibers, during thermal curing and/or pressurization as the factors of burst-mechanism, for establishment of ‘thin-layer filament winding evaluation method’. Under the situation, we have been investigating the influence of manufacturing error on meso-scale parameters to the burst-strength, by changing the conditions, such as layer-composition or winding angles of both multi-filament winding and single-filament winding.

(4) Investigation to Exemplify Optimum Design of Multi-filament Winding Tank
We have decided the tank spec. Based on the tank spec, we investigated the required spec of filament winding machine. Finally, we have made the detail spec of filament winding machine.
