Abstract
Disclosed are: damage-resistant ECMCs that need to work and remain elastic between minus 120° C. and positive 300° C.; ECMCs that need to be able to contain a flame of 1900° C. for more than 90 minutes; and composite structures, especially highly stressed structures. One of the characteristic problems of ceramic matrices is their fragility. Indeed, when a fracture starts, it propagates easily in the matrix. Disclosed are elastic ceramic matrix composites (ECMCs), for which: the ceramic matrix is split into solid “ceramic microdomains” (CMDs); the CMDs are connected to one another by a dense network of “elastic microelements” (EMEs); and the bonds between the EMEs and the CMDs are strong chemical bonds, preferably covalent.
Claims15
A production method of a ceramic composite with an elastic matrix, the method comprises the following steps:
- Step 1:
- an admixture comprising at least one of the following elements is dispersed in water an alkali an acid, to obtain “an adjuvant in aqueous solution”,
- Step 2:
- then, in the said adjuvant in aqueous solution, an additive is reacted to obtain a “mineral hardener”
- Step 3:
- Finally we prepare a “mineral resin powder”
- Step 4:
- said mineral hardener is poured and intimately mixed into said mineral resin powder to form a “ceramic mixture” the said process is characterized by the fact that the following steps that can be performed, either following or before some of the preceding steps, are added:
- Step 5:
- the preparation of a “fluid silicone homopolymer with active terminations” is carried out,
- Step 6:
- during this step, the dispersion of a homopolymer of fluid silicone with active terminations, is realized, either after step 3 or after step 4 to obtain said “elastic ceramic mixture”
