First composites never feature metallic bases.
00:15
So here if we see for its answer, so it is false.
00:18
Now the reason behind it that also we have to discuss.
00:23
So the composites have two pieces.
00:24
First of all, we talk about the matrix space and the second is what it is the reinforcement face.
00:32
The reinforcement phase is what it is a fiber shields or particles in the mattresses faces can be metal, ceramic or polymer.
00:43
So it can feature metallic face.
00:48
Second, now here we talk about the structural composites such as carbon fiber composite typically exhibit very high densities.
00:58
So here this is statement it is also false.
01:01
Now why it is so we should know the reason about it.
01:04
So the density of carbon fiber epoxy mattress composites is usually 1 .75 to 2 grams per centimeter cube and which is significantly low...
