The given polymer, and composite materials, can be subjected to various thermal conditions during their processing and applications. This necessitates the understanding of their thermal characteristics. The thermal degradation behavior of the composites was experimentally explored by using a Thermo-Gravimetric Analyzer under atmosphere nitrogen.
How to relate the thermal stability of the given material with strength?
Dear Kassahun Gashu Melese, first define which strength you mean with respect to the stress(es) thé material is subjected and thé form of déformation: Creep, cycling, ... The following documents may be helpfull. My Regards

Dear Kassahun Gashu Melese ,
I believe you can measure the temperature at which your material loses 5% of its initial weight and report it. Also, the residual weight after performing the test might reflect the thermal stability of your material. You can compare the obtained results with similar data in the literature and conclude the impact of additives in your composite system.
Dynamic Mechanical Thermal Test (DMTA) along with DSC analysis might help you evaluate the thermo-mechanical properties of your material even more precisely.
Hope this help.
Dear Melese,
The amount of heating required depends on the degree to which the ion is polarized. More polarization requires less heat. The smaller the positive ion is, the higher the charge density.
(1) Correlation of thermal stability and hardness, as thermal stability increases hardness decreases due to strain induced more here.
(2) Influence of Processing Conditions improves the thermal stability and mechanical properties composites due to weight reduction and combination of fiber orientation as well. Just example, Addition of silica to lignin via this new hybrid formulation has a positive effect on the thermal stability of PP/silica-lignin composites, which can be seen even when observing the temperature for the maximum rate of weight reduction. Tensile test results show that the addition of silica by means of dual filler incorporation improves the mechanical parameters in comparison with pure PP and PP/lignin composite.
(3) In building industry, thermal capacity of a building is in direct ratio to the construction thickness. Thermal stability of wet high strength concrete is less than thermal stability of dry high-strength concrete, since alternatively thermal properties of the basement areas will differ considerably from thermal properties of the building superstructure. So dry concrete have better thermal; stability.
