Description
Technical field
The present invention relates to the hand paste of chemical industry and technical field of composite materials, more particularly, to composite shaping and repairing
The brilliant wind-powered electricity generation level hand paste resin system of resin system and preparation method thereof, more particularly to a kind of resist sagging and resistive connection and its preparation side
Method.
Background technology
Hand paste technique is to manufacture one of conventional method of composite main flow, and its process principle is to paste resin system using hand
Impregnated fibrous braid, then lays its lamination and the laminating that presses, and composite wood is formed after resin system solidification to be impregnated
Expect matrix.Although but still widely used it now appear that technique hidden danger and quality problems easily occur for hand paste technique, even in all
Such as MW grades of wind electricity blade large-scale advanced composite material also must partly use this process when preparing.
Hand paste technique pastes resin machine-shaping composite using hand, due to being manual operations, die sinking operation, therefore by work
The influence of people's skilled operation and the cognition and comprehension degree and environmental condition is larger, it is possible to cause the imbalance of component mixing ratio, life
Produce the problems such as efficiency is low, many, the resin solidification degree of raw material consume is relatively low, dust impurity is mixed into, product quality fluctuation is larger.Institute
So that hand pastes resin should be wide in range enough for the tolerance of various influence factors.
With the development of Modern Composite Materials technology, hand paste resin system kind is enriched constantly, the introducing of new raw material
