Description
Technical field
The present invention relates to a kind of prepreg cloth, be specifically related to a kind of basalt fibre and strengthen thermosetting resin prepreg cloth.
Background technology
The preparation process of fiber-reinforced resin matrix compound material be fiber and resin fully infiltrated, impregnate after, Jing Guogu
The change stage is prepared from.In this process, resin is difficult to accurately control its resin content with the dipping of fiber sometimes,
In the field high to material requirements, substantially just cannot use.And prepreg cloth is just to solve this problem, the preparation of prepreg cloth
Journey head the most accurately controls temperature and the viscosity of resin, the then accurate content controlling to be immersed on fiber, thus reaches accurate
Control fiber and the content of resin in prepreg cloth, be suitable for the field of each high-end requirement.
At present, the prepreg cloth major part on market is all carbon fibre initial rinse fabric, is preparation after impregnated carbon fiber epoxy resin
Prepreg cloth, occasionally have glass fibre prepreg cloth.Carbon fibre initial rinse fabric typically uses glued membrane method to prepare, will carbon cloth warp
Creel is drawn so that it is after smooth row's paving, be sandwiched between two dry glue films prepared, and forms a sandwich knot
Structure, then allow it make in carbon cloth embedded resin by hot-pressing roller, resin departs from paper membrane and infiltrates on carbon fiber simultaneously, is formed
Prepreg cloth, finally adds a cover isolating membrane, release paper, is compacted rolling.This process device become more meticulous degree require height, operation complexity, energy
Consume higher, then owing to the price of carbon fiber material own is the highest, so carbon fibre initial rinse fabric price is high, being not suitable for large-scale popularization should
With.
