Flexibel mould design

Project duration June 2018 - October 2018
Status Completed
Venture Strategic Innovation Programme on Lightweight

Purpose and goal

In this project, the goal was to use modular tools for different dimensions when injecting dry 3D woven I profiles. Cost of tools can thus be reduced and lead times can be shortened. In the developed tool, a prototype concept is shown, with the ability to change different parts in order to produce profiles of different dimensions.

Expected results and effects

The developed tool in this project will be used to inject beams of different dimensions to be tested to evaluate the characteristics of the dimensions. The result shows that it is possible but further studies are needed to clarify how a safe and quality assured use of the tool can be done before the method can be used for larger tools, and thus provide an efficient production chain of carbon fiber profiles.

Planned approach and implementation

A tool concept was developed for a prototype tool with manual adjustment of different modules to suit the various 3D weaves. Conventional methods for sealing the modules were selected with Silicon O-rings, centering of centers with centering pins and assembly with bolt joints. Injection channels were engineered for different injection strategies. Selection of materials and plates, made at the shortest lead time and minimal processing. Dimensions adjustments with shims should be avoided in series production, high risk of assemling misstakes and disposal of production details.
