From larger-scale prototypes to the smaller details of molding, Chavant Modeling Clays provide a unique solution to getting it just right for your composite project.

  • Clay is smooth and workable; it's easily shaped and carved.
  • Clay holds great detail at the surface.
  • It offers impressive adhesion qualities that make it well-suited where other reinforcements and composite elements won't work.
  • Clay resists shrinking and cracking.
  • All Chavant brand clays are sulfur-free, low odor, and non-toxic.

Even for the simplest, but critical task of parting lines for mold-making, clay is a smart addition to the composite workshop.

Which clay should I select?

  • Choose Chavant Le Beau Touché and Chavant Le Beau Touché HM clays for temporary fillets, construction of mold parting lines, and quick mold repairs.
  • Choose Chavant AutoStyle and Y2-Klay Industrial Design clays for larger-scale prototypes in transportation and product design, as well as for sculpting applications in art and special effects.

Carefully read through individual product descriptions to match the clay to your project.

Modeling clay is a versatile material that can be used in composite work for various purposes. Here are some key aspects of using modeling clay in composite applications:

  1. Conceptual Design: Modeling clay is often used in the initial stages of composite product development for creating concept models and prototypes. Its malleability and ease of shaping allow designers and engineers to explore different forms, contours, and surface finishes.
  2. Tooling and Mold Making: Modeling clay can be used to create patterns and molds for composite manufacturing. It is used to sculpt the desired shape or form, which can then be used as a master pattern for creating molds or tooling. Clay provides flexibility during the pattern-making process and allows for precise detailing and modifications.
  3. Surface Finish and Detailing: Modeling clay is useful for adding fine details and surface textures to composite products. It can be sculpted and manipulated to achieve intricate designs, curves, and features that may be challenging to create directly in composite materials.
  4. Dimensional Verification: Modeling clay can be used to verify and refine the dimensions of a composite part before production. By creating a clay model that matches the intended shape and size, engineers can visually assess and measure the prototype for accuracy and make necessary adjustments before moving forward with composite manufacturing.
  5. Repair and Modification: Modeling clay is also helpful for repairing and modifying existing composite parts. It can be used to fill gaps, blend edges, or reshape sections that may have been damaged or require adjustments. The clay can be easily sculpted and smoothed to seamlessly integrate with the existing composite structure.
  6. Compatibility with Composite Materials: Modeling clay is typically compatible with composite materials, including fiberglass, carbon fiber, and epoxy resin. However, it's essential to consider the specific clay composition and any potential interactions or reactions with the composite materials being used. Compatibility tests or consulting with Fibre Glast technical support can help ensure the clay's suitability for a particular composite application.
  7. Non-Permanent Nature: Modeling clay is non-permanent and can be easily reworked or removed when needed. This makes it a flexible material for experimenting, refining designs, and making changes before committing to the permanent composite production process.

When using modeling clay in composite work, it's important to consider the temperature sensitivity of the clay. It can become soft and malleable when exposed to heat, so appropriate precautions should be taken to prevent deformation during the composite manufacturing process, such as cooling or stabilizing the clay pattern.

Overall, modeling clay offers a valuable tool for composite work, providing a hands-on approach to design, patternmaking, detailing, and verification. Its versatility and ease of use make it an effective medium for exploring and refining composite product concepts before transitioning to final fabrication.
