Definitions
- the invention relates to a method for the maturation and thickening of SMC semifinished product (sheet molding compound) and BMC semifinished product (bulk molding compound).
- a method for the production of fiber reinforced components according to the SMC process is known.
- a resin-filler mixture is knife-coated onto a carrier film.
- cut fibers can also be sprinkled onto the carrier film.
- Uncut quasi-infinite unidirectional fibers can be introduced into the semi-finished product from an additional position.
- the material is then covered with another resin-coated backing film and passes through a flex zone for impregnating the reinforcing fibers.
- the Harmatte is then wound on rolls, for example, and transported to a maturing warehouse as a so-called semi-finished product. After the required thickening, the viscosity increase, of the semi-finished product is reached, further processing can take place.
- the carrier film required for the production of semi-finished products is pulled off to the end product before pressing, in which the polymerization takes place.
- the SMCJBMC paste contains thickenable polyester resin, for example UP resin (unsaturated polyester resin) or VE resin (vinyl ester resin), which is subjected to the so-called thickening / maturation by adding polyvalent metal compounds, for example magnesium oxide or magnesium hydroxide.
- thickenable polyester resin for example UP resin (unsaturated polyester resin) or VE resin (vinyl ester resin)
- UP resin unsaturated polyester resin
- VE resin vinyl ester resin
- Metal compounds must be added before processing on the SMC system.
- the process of thickening is influenced, among other things, by the one used
- Polyester resin other components but also by the temperature and the Water content of the paste as well as the water content of the individual components including the glass fibers.
- the invention has for its object to provide a method in which the above deficiencies in thickening / maturing are avoided.
- the task is solved by using suitable electromagnetic beams to accelerate thickening and maturation.
- the electromagnetic wavelength spectrum extends in the preferred range from approximately 100 m, the initial range of the short wave, to the limit of infrared light at approximately 760 nm, which corresponds to the frequency range between 10 6 and 10 15 Hertz.
- the duration and intensity of the irradiation and the selection of the wavelength or frequency is dependent on the composition of the semi-finished product, in the case of so-called Class A LP-SMC, preferably in the range from 0.9 to 2.6 GHz.
- the process of thickening the BMC / SMC paste and the SMC semi-finished product (resin mat) can take place more quickly and in a controlled manner.
- the irradiation can be carried out directly on an SMC / BMC system.
