How the natural fibre withstand the heat while fabricate?
In this journal paper they mix the aluminium with natural fibre my question is - How the natural fibre withstand the heat while fabricate?

Did you read the full paper? The method of fabrication is described in the paper. They claim that powder metallurgy techniques were used. The sintering was done by them at 2000C.
Coconut fibre should stand this.
It is a different matter that in my opinion one would require nearly 5000C to sinter Aluminium.
My mistake. Aluminium sinters at 5700C.
thanks for your respond sir , yes i read the paper sir first they blended all the raw materials then they go for the fabrication if the firbre withstand that temperature but without melting aluminium powder how they made the break pad because aluminium melting temperature is 6300C
A longtime back I was involved with powder metallurgy related activity. As a general rule, sintering temperatures are about 80 to 85% of the melting temperature.
In the referred paper all compositions use 10% phenolic resin. This would translate into 20% volume percentage. The aluminium powder would remain as is. All they would have got is a resin bonded abrasive pad, which is fairly common. The resin would sinter at this temperature depending on the specific resin. I had made phenolic resin bonded iron cylinders with this kind of volume percentages.
As per your statement the 2000C is enough to make the aluminium break pad composite?
The composition shown in the paper should cure at 2000C.
