Primes are numbers with two factors and there's no formula for the nth one, right?
Well, what about other numbers with 4, 6, 8... (I exclude odd numbers as these are square numbers and therefore very rare) factors can they predict the nth one of these? I think not. Why are ...

Fiberglass is composed of thin glass fibers and a plastic resin (usually epoxy). The thin strands of glass are very strong but, by themselves, are like strands of haor or fiberglass insulation. The resin binds the strands together to make a solid substance and to take advantage of ...

what are the general characteristics of partticle-based composites?
If you are referring to composite wood products, their marketable characteristics are large size, high uniform strength, and reliability. The overall strength of parallel strand lumber is superior to the best grades of Douglas-fir or southern pine lumber.

What are the specific strength and specific stiffness? Why are they (specific
strength and specific stiffness) defined. and also what are the advantages and disadvantages of FRP composites?
By way of answers, you can find a lot of discussion at places like this:

I was reading that a tensile-truss made of carbon nanotubes could be used to hold together engines and modules in zero gravity. I know that, by using the word "tensile", it means that the truss is like wiring or cables, and can bend and adjust when loosened. But ...
