| abstract |
The present invention relates to a method for producing a storage-stable prepreg and a molded body (composite structural member) produced from the method. In the present invention, reversibly crosslinked composites or storage stable prepregs are produced, for example, by heterodiels Alder reaction (HDA) of PMMA polymers. When the temperature is adjusted slightly higher, the prepreg can be decrosslinked again as long as the prepreg can be molded by a retroheterodiels alder reaction. Moreover, the reverse reaction to recrosslinked products or high molecular weight products is carried out at room temperature. |
