Abstract:
The present invention relates to a liquid (meth)acrylic syrup for impregnating a fibrous substrate. The present invention relates in particular to a viscous liquid syrup mainly containing methacrylic or acrylic components. The invention also relates to a process for manufacturing such a syrup. The invention also relates to a process for impregnating a fibrous substrate comprising long glass fibers with said viscous liquid syrup. The invention also relates to a fibrous substrate preimpregnated with said syrup, which is useful for manufacturing transparent parts especially for the building sector. The present invention also relates to a manufacturing process for manufacturing transparent parts obtained via this process.
