Mould making for composite components is a fundamental field that is absolutely crucial for the success of projects. In mould making, problems are solved before they arise – or, on the contrary, numerous problems arise that show up in later production phases and often cost the company dearly. In the case I would like to …

It happens again and again that composite components in series production have to be reworked manually. In this case, it was a question of recesses in the core material for inserts for the subsequent screw connection of the components. Unfortunately, depending on the shape of the inserts, this cannot always be done during the layer …

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 …

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 …

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 …
If you want to bring a composite component to series production, some problems can arise. A good example of this is a component with Nomex® Honeycomb as core material, which is produced using autoclave technology. Nomex® Honeycomb is a wonderful core material with many advantages, but like all composite materials and processes, it requires practical …

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, …
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 …
