Safety assessment is generally done by conventional mechanical methods such as uniaxial tensile and fracture mechanical test, etc.
For example, nondestructive methods are needed to determine properties in a specific parameter.
This technique can nondestructively evaluate various mechanical properties such as residual stress, tensile properties, and fracture toughness by analysis of the indentation load-depth curve [1-3].
Tensile properties measurement using IIT Tensile properties can be evaluated by defining representative stress and strain with parameters obtained from instrumented indentation tests using a spherical indenter.
The tensile properties measurement used a WC ball indenter (radius 250 µm).

However, these phases deteriorate the high temperature mechanical properties and also affect the oxidation behavior of ceramics composites.
III.3 Mechanical properties For both sintering aids, the mechanical properties results were similar.
The inhomogeneous mixture may be responsible for a decreasing of mechanical properties [27].
This behavior can produce mechanical properties anisotropy, principally, the fracture toughness [28-29].

In particular, the mechanical properties of products of the red ceramic have been poorly studied.
After the sintering stage it was determined the following properties: water absorption, linear shrinkage, apparent porosity and mechanical bending resistance in three points.
Several factors can affect the water absorption, such as, the nature of the clay minerals that constitute the raw materials used, their particle size distribution and phase transformations.

According to SOUZA [9] the combination of factors, such as, temperature and time during the sintering (thermal cycle) can affect the degree of sintering suffered by a ceramic body during the firing.

These factors have important effects on the mechanical properties of propellant.
As a result, the mechanical properties of HTPB propellant are remarkably enhanced.
On this condition, formula 4 has better mechanical properties than formula 2, because the content of binder in formula 4 is larger, the effect of the matrix cross-linking net structure of binder on the mechanical properties has emerged.
It can be concluded that bonding agent can remarkably enhance the mechanical properties of propellant.
The interface reciprocity between the binder and filling particles is the primary factor to the mechanical properties of HTPB propellant.
