Foundry aids made of fiber-reinforced oxide ceramics for the aluminum foundry

Motivation

The project aims to develop round-needled ceramic preforms as innovative materials offering exceptional thermal stability and mechanical strength. These preforms provide novel solutions for high-temperature applications, particularly in foundry technology. By reducing aluminum melt adhesion and iron contamination, as well as improving thermal insulation and the durability of foundry aids, the project has the potential to significantly enhance energy efficiency, conserve materials, and improve product quality. Research and optimization of textile processes for brittle ceramic fibers represent both a scientific and technical challenge, with the promise of groundbreaking advancements in materials science and its industrial applications.

The project has several key objectives:

  • Reduce aluminum melt adhesion by 90% and improve melt purity
  • Increase the service life of foundry aids by a factor of five
  • Optimize thermal insulation to enhance energy efficiency
  • Develop stable, round-needled preforms suitable for various industrial applications
  • Enable cost-efficient production of near-net-shape preforms with improved mechanical stability

These measures aim to provide energy-efficient and durable solutions for high-temperature industrial applications.

Approach

Needle-punched fiber preforms in single-component and multi-component designs (different fiber types)

The approach includes optimizing the handling of ceramic fibers by surface modification and improved carding processes. Flat needling is used to achieve Z-directional reinforcement, while round-needling technology is further developed to produce dimensionally stable preforms. Carefully selected ceramic fibers enhance both thermal insulation and infiltrability. Near-net-shape preforms are created using cutting and draping tools and undergo mechanical testing. Finally, industrial integration is facilitated through the adaptation of preform systems to specific application requirements.
