The objective of the project is to generate design methods for selected advanced ceramic matrix composites which encompasses component performance, production routes and materials. The objectives are:
new and enhanced ceramic matrix composites with flexural strengths and fracture toughness up to 500% greater than unfilled matrix materials with Weibull moduli in excess of 20;
ceramic matrix composites capable of continuous operation in air at temperatures above 1000 C;
composites which when overstressed, fail by a relatively controlled nonbrittle mechanism;
quantified mechanical property data of new and enhanced composite systems suitable for materials design;
design codes and computer programmes to enable economic design of composites developed in the project and new composites;
demonstrators which assess the performance of design codes.
A broad range of reinforcing fibres and particulates have been sourced. Evaluation has been initiated of inclusion compatibility with selected glass and ceramic matrices.
Ceramic fibre ceramic matrix combinations have been identified which are not detrimentally affected by temperatures up to and including 1200 C.
Composites that were made employed techniques suitable for the fabrication of complex geometry components requiring 2-dimensional and 3-dimensional fibre architecture.
Preliminary mechanical evaluation of fibre reinforced composite material has yielded mean 4-point flexural strengths about 700% greater than the unfilled matrix material.
The lacks are:
-new and enhanced ceramic matrix composites with flexural strengths and fracture toughness up to 500% greater than unfilled matrix materials with Weibull moduli in excess of 20
-ceramic matrix composites capable of continuous operation in air at temperatures above 1000 degrees C
-composites which when over-stressed, fail by a relatively controlled "non-brittle" mechanism
-quantified mechanical property data of new and enhanced composite systems suitable for materials design
-design codes/computer programmes to enable economic design of composites developed in the project and new composites
-demonstrators which assess the performance of design codes.
