For rotation-symmetric items – high mechanical performance, economical and scalable
The fibre orientation gives the components the desired strength and stiffness. The hardened polymer matrix holds the fibres together in the final component and leads to optimal force transmission from fibre to fibre. This results in a consistently high material quality and ideal technical properties.
Advantages of prepreg autoclave technology are:
“Prepreg” stands for “pre-impregnated fibres”. Prepreg consists of continuous fibres and a not-yet-fully-hardened, mostly thermo-set polymer matrix. The fibres can be present as a unidirectional layer, as a woven or non-woven fabric.
Prepregs are precisely cut on the cutter and placed in layers in the defined sequence and orientation into a mould until the defined laminate structure is created. A well-defined fibre orientation gives the components the desired properties such as elasticity or rigidity.
The mould including the component is then evacuated in a temperature-resistant foil bag and cured under pressure and heat in a numerically controlled autoclave. This takes typically 4 to 7 hours depending on the type of material and the size and quantity of the items in the autoclave. The component is then cooled in a controlled manner, removed from the mould (demoulding) and processed further.
