Faulty curvature and displacement of the core material in composite materials

One customer repeatedly experienced an increase in scrap during the production of components made of composite materials. The causes were bulges, displacements and gaps in the core material (see figure above). (The visible small wrinkles are not the subject of this article, I have already dealt with these in an earlier blog post on the …

Why the precise cutting of the peel ply is so crucial for a successful component back

Even if we are talking about the backs or B-sides of components – in many cases the optical demands are still high in practice. Difficulties are often caused by the development. The illustrated component was designed on CAD and there it had a perfect back side (Class A Surface) in the 3D model. Thickness tolerances …

Technisches Problem in Composite-Produktion

The different ways of thinking of departments when it comes to technical problems and solutions

Do you know it? There are problems in production and the different departments involved, such as production, quality and development, are not getting the issue solved. In addition to the personal distance of the people involved, there is often also the physical distance. The consequence: responsibility is passed on in the circle of departments. I …

Avoidance of problems in the development and production of series components in composite

A topic that I encounter again and again in my consulting work is the development of composite components and their subsequent production in series. Already during development, the course is set for possible problems in production, which then result in expensive reworking or rejects. An example is shown in the picture above: In this component, …

Carbon Composite Optimization: Example of a quality improvement of visible carbon components

A component with visible carbon optics had an optical problem due to unsightly distortion of the fabric. As a result, the fibre flow did not meet the customer’s high aesthetic requirements for a visible carbon surface. The task was to optimize the component and get it approved by the OEM. This was done in close …
