Conclusions
-
1.
It has been established that the strength of CRP is most affected by the type of filler in the temperature range 293–1000°K with tension, and least affected with compression. Whereas the maximum amplitude between the greatest and least values of relative strength for CRP with compression is a little more than 20%, with tension it is 50%.

2.
Reinforcement of CRP by different types of filler in the test temperature range also has a marked effect on their elasticity properties. For example, under tensile conditions at 873°K the elasticity modulus of CRP reinforced with TMP-4 fabric is maintained at 80% of the initial value, whereas the elasticity modulus for CRP reinforced with carbon knitted cloth with a pyrocarbon coating is only retained at 10%.
