The new Prepreg Pre-Cuts represent an interesting addition to our Prepreg portfolio. The pre-cut pieces are available in many practical shapes, and in a large selection of sizes.
Using these Pre-Cuts will make for an especially quick and uniform working process, and it will help you in creating especially even and precisely worked custom Prepreg pieces without having to spend much time on cutting the Prepreg into the required shape.
All available shapes and sizes can be found in our current Materials Catalog.
Prepreg Technique vs. Manual Lamination
Wet or manual lamination is the oldest and comparatively most simple procedure for manufacturing orthopedic components. CFK reinforcement layers are soaked in resin and laminated by hand. The component is then cured under vacuum film, where excess resin gets extracted by suction. Concerning fiber volume ratio, reproducibility and component complexity, manual laminates are considerably weaker than other production methods. The manual application of resin makes it hard to achieve a specific, even and constant resin content all over the component. It is also harder to add additional or reinforcing layers in an exact manner.
Achieving an even resin content within the component is much easier when using prepreg material (i.e. pre-impregnated textile semifinished fiber-matrix material). The mechanical impregnating process secures an even saturation of the fibers with epoxy resin and hardener, thus allowing for both ideal reproducibility and maxiumum stability of the carbon components. To ensure that the vulcanization will not be triggered prematurely, it is important to make sure that the cold chain during storage remains virtually uninterrupted. Components produced using the prepreg technique – which require comparatively little manual retouching – are also aesthetically pleasing: This is why they are also often used as visual components in discerning industrial sectors such as the automobile or aviation industry. Thus, producing an orthopedic component with prepreg materials is recommendable whenever you have especially high demands on the component ‘s capacity to withstand strain and dynamic stress. Using prepreg materials will lead to reproducible results which are pleasant to both eye and touch.
