Experimental Materials.
A ASTMM1354 type cone calorimeter (Fire Testing Technology Ltd., UK) was used to test the fire performance of the materials, under an external heat flux of 35 kW/m2.
Concerning thermogravimetry (TG), it is widely used to investigate the thermal stability of the materials.

Fabrication of Self-Healing Ceramic Coatings Against Oxidation for Carbon/Carbon Composites Using Polysilazane and B4C Filler Chunying Tiana, Hongli Liub College of Materials Science and Engineering, Jiamusi University, Jiamusi 154007, China a tcywkx@126.com, b lhl@mse.buaa.edu.cn Keywords: Self-healing; coatings; C/C composites; Filler Abstract.
Introduction Carbon/carbon (C/C) composites are considered as the promising candidate materials for high temperature structural applications.
A number of techniques such as chemical vapour deposition, pack cementation, evaporation, sputtering and plasma spraying have been used to provide coatings for C/C composites with oxidation-resistant materials.
However, in spite of its advantage, work reported on the coating of carbon fibers or C/C composites with different oxidation-resistant materials using this technique is quite scanty.

A typical starch granule consists of small amounts of proteins, lipids, phosphorus and inorganic materials [5].
The amounts of proteins, lipids, phosphorus and inorganic materials are changing from source to source (Table -2).

Experimental Procedure Materials.
Melamine 99.0% (Merck), 37% formaldehyde solution (Loba chemie), 99.9% Methanol (RCI Labscan), 98% NaOH pellets (Sigma-Aldrich) and 37% Hydrochloric acid (Lab-Scan Analytical Sciences) were used as received.
The curing time is also important to the structural stability of the cured materials.
This work also paves a new route towards mesoporous melamine resins materials and even new advanced porous composite materials with cheaper and more accessible starting reagents.

However, with regard to welded structures, fatigue strength has little to do with static strength of base metal, weld metal, structure property of HAZ and intensity match of welding material.
In addition, mechanical property of materials has some effect on crack propagation rate, but not great.
With the continuous development of science and technology, new measures improving fatigue property of welded structures will continue to emerge, and effect will be even more significant.
