Step 3, lures curing agent reaction into, makes fiber ceramics idiosome be solidified into fiber ceramics composite.The present invention prepares fiber ceramics composite by the method for press curing, has the advantages that technique is simple, efficiency is high.
Fiber dust preferred glass fibers powder in step 1.Can be long glass fibres powder, can be also the short glass powder of cutting.Glass fibre is to have good insulating, heat resistance is strong, corrosion resistance good, mechanical strength is high feature.And it manufactures through high temperature melting, wire drawing, doff, the technique such as weave cotton cloth take glass marble or discarded glass as raw material, have the advantages that cost is low.In step 1, fiber dust can also be ceramic fibre, and ceramic fibre is a kind of lightweight refracrory, has lightweight, high temperature resistant, Heat stability is good, thermal conductivity is low, specific heat is little and the advantage such as resistance to mechanical shock.
And, in fiber ceramics powder mixture, can also sneak into bonding agent, further to improve bonding strength everywhere.
Curing agent in step 1 can be thermal curing agents, light curing agent.When adopting thermal curing agents, step 3 can be lured curing agent reaction into by the mode of heating.When adopting light curing agent, step 3 can be lured curing agent reaction into by the mode of ultra violet lamp.Certainly also allow two kinds of curing agent to coexist.While adopting thermal curing agents, preferably high temperature thermal curing agents.Step 3 is lured the reaction of high temperature thermal curing agents into by the mode of high-temperature firing.
In step 2, first layering compacting, then by each layer of stacking moulding, then suppresses, and forms fiber ceramics idiosome.Also can first suppress one deck, then on the layer suppressing, feed in raw material and suppress again, then repeat the reinforced process of compacting again, until moulding forms fiber ceramics idiosome.
In step 2, can not adding between the layers any is not the material of fiber ceramics powder mixture.Intensity is consistent everywhere for the fiber ceramics composite solidifying to form with assurance.Also can add between the layers adhesive, increase the intensity of junction by adhesive.
Above-mentioned two methods have effectively improved the tight ness rating of piling up, and can, by above-mentioned two methods, obtain fine and close fiber ceramics idiosome.
The present invention can also adopt following technique, first by fiber ceramics powder mixture compacting stratification, form Fiber Laminated pottery idiosome, then lure curing agent reaction into, make Fiber Laminated pottery idiosome be solidified into Fiber Laminated ceramic composite, then by the stacking moulding of a plurality of stratiform fiber ceramics composite, and each adjacent two-layer Fiber Laminated ceramic composite is connected, forms fiber ceramics composite.
Can two-layer Fiber Laminated ceramic composite be connected by adhesive.Also can between two-layer Fiber Laminated ceramic composite, add fiber ceramics powder mixture, then lure the curing agent reaction in fiber ceramics powder mixture into, two-layer Fiber Laminated ceramic composite is connected.For example, lure its reaction into by the mode of calcining.
