Description

2 46l 2.75 upptagande och brottsäkrande effekten pa grund av det samtidiga fiberbrot- tet skulle ga förlorad. 2 46l 2.75 uptake and break-proof effect due to the simultaneous fiber break would be lost.

Mellanskiktet av fibrer enligt uppfinningen förhindrar vid oskadad keramik en icke önskvärd kraftig värmeöverföring genom strålning och/eller konvektion. Vidare kan mellanskiktet övertaga en mjuk kraftöverföring till stödjande strukturer och utjämna värmeutvidgningsskillnader mellan keramik och eventuellt stödjande kärnor. Vid sprickbildning eller brott uppnås ett bättre felsäkerhetsförhållande, eftersom keramikfibrerna icke på långt när är sä känsliga mot den omgivande varma gasen som metalltrådar.In the case of undamaged ceramics, the intermediate layer of fibers according to the invention prevents an undesirably strong heat transfer by radiation and / or convection. Furthermore, the intermediate layer can take over a soft power transfer to supporting structures and even out thermal expansion differences between ceramics and any supporting cores. In the event of cracking or breakage, a better fail-safe condition is achieved, since the ceramic fibers are not nearly as sensitive to the surrounding hot gas as metal wires.

Ett lämpligt framställningsförfarande utmärker sig genom att fiberskiktet inlägges i en lerform innan den egentliga sintringen påbörjas.A suitable manufacturing process is characterized in that the fibrous layer is placed in a clay mold before the actual sintering begins.

Alternativt kan emellertid även fiberskíktet före isostatpress- ningen inläggas i en pressform och därefter inpressas i kerarnikmatrisen.Alternatively, however, the fibrous layer can also be inserted into a mold before the isostat pressing and then pressed into the core matrix.

Som keramikfibrer kommer särskilt oriktade fiberskikt såsom filtmattor eller riktade fiberskikt ifråga (enriktad väv).Suitable ceramic fibers are particularly non-directional fibrous layers such as felt mats or directional fibrous layers (unidirectional fabric).

Genom uppfinningen utnyttjas sålunda för den egentliga kompo- nenten samt för komponentens förstärkning artbefryndade keramikmaterial, för att utjämna olika karaktäristik för materialen såsom är fallet vid den inledningsvis nämnda teknikens ståndpunkt. Den enligt uppfinningen framstäl- lda keramiska sammansatta komponenten har en enhetlig elasticitetsmodul.The invention thus utilizes species-enriched ceramic materials for the actual component and for the reinforcement of the component, in order to even out different characteristics of the materials as is the case with the state of the art mentioned in the introduction. The ceramic composite component produced according to the invention has a uniform modulus of elasticity.

Temperaturomradet vid användning är betydligt större än vid användning av metalliska förstärkningstrådar. Jämte den kemiska sintringsprocessen sker inga ytterligare kemiska reaktioner mellan de enskilda materialen. Värmeut- vidgningsskillnader mellan fiberskiktet och keramikmatrisen uppträder icke.The temperature range during use is significantly larger than when using metallic reinforcing wires. In addition to the chemical sintering process, no further chemical reactions take place between the individual materials. Thermal expansion differences between the fiber layer and the ceramic matrix do not occur.

Därmed förbättras avsevärt genom uppfinningen särskilt felsäkerhetsförhål- landet mot katastrofala fel i komponenter (brott med lösa brottstycken).Thus, the invention significantly improves, in particular, the fail-safe condition against catastrophic faults in components (fractures with loose fragments).

Enligt uppfinningen framställda keramikkomponenter kan särskilt vara bränn- kammarrör och turbinskovlar, som i värme och/eller mekaniskt utsättas för kraftiga pakänningar.Ceramic components produced according to the invention can in particular be combustion chamber pipes and turbine blades, which in heat and / or mechanically are exposed to strong packing stresses.

Uppfinningen skall i det följande närmare beskrivas med hänvis- ning till bifogade ritning.The invention will be described in more detail below with reference to the accompanying drawing.

Fig. l visar en enligt uppfinningen framställd (enkel) keramikkomponent.Fig. 1 shows a (simple) ceramic component produced according to the invention.

F ig. 2 visar en annan keramikkomponent med inlagt förstärkningsfiberskikt.F ig. 2 shows another ceramic component with inlaid reinforcing fiber layer.

Den i fig. l visade keramikkomponenten innefattar en oförstärkt keramikmatris 1, som på sidan är belagd med ett fiberskikt av artbefryndad keramik. För framställning av komponenten anbringas keramikfiberskiktet 2, som kan vara en oriktat filtmatta eller ett riktat fibermaterial i form av en väv, på utgångskroppen. Genom det påföljande sintringsförloppet inträffar en 3 461 275 förening mellan keramikmatrisen 1 och förstärkningsfiberskiktet 2, varvid fiberskiktet icke fullständigt införas i keramikmatrisen (delvis homogen sinterförening). Den endast delvisa utbildade sinterföreningen mellan mate- rialen sörjer för att vid brott matrisen icke samtidigt utsättes för ett fiberbrott. Därigenom kan det artbefryndadegkeramiska fiberskiktet fungera som förstärkningsskikt i den egentliga utgàngskroppen av keramik.The ceramic component shown in Fig. 1 comprises an unreinforced ceramic matrix 1, which is coated on the side with a fibrous layer of species-enriched ceramic. To produce the component, the ceramic fiber layer 2, which may be an unidirectional felt mat or a directional fibrous material in the form of a fabric, is applied to the starting body. As a result of the subsequent sintering process, a connection occurs between the ceramic matrix 1 and the reinforcing fibrous layer 2, the fibrous layer not being completely introduced into the ceramic matrix (partially homogeneous sintering compound). The only partially formed sintering compound between the materials ensures that in the event of a break the matrix is not simultaneously exposed to a fiber break. Thereby, the species-enriched ceramic fiber layer can function as a reinforcing layer in the actual starting body of ceramic.

Den i fig. 2 visade keramikkomponenten innefattar ett fiberskikt 2 av keramik, som före-sintringsförloppet är fullständigt infört i utgàngskrop- pen. Förstärkningsfiberskiktet 2 befinner sig sålunda mellan tvâ keramikskikt för att förstärka desamma.The ceramic component shown in Fig. 2 comprises a fibrous layer 2 of ceramic, the pre-sintering process is completely introduced into the starting body. The reinforcing fiber layer 2 is thus located between two ceramic layers to reinforce them.

Vid framställningen av keramikkompnnenterna kan fiberskiktet exempelvis inläggas i en lerform. Skiktet kan emellertid även före isostat- pressningen läggas och inpressas i pressformen Lex. pa en kärna.In the production of the ceramic components, the fibrous layer can, for example, be laid in a clay mold. However, the layer can also be laid and pressed into the Lex mold before the isostat pressing. on a core.
