Introduction Nano-organic composite material is a kind of composite materials based on organic polymer materials for the continuous phase and inorganic nano-powders for the reinforcement.
Among them, nanofibers reinforcement composite materials receive much concern due to their excellent properties and unique structure [1-2].
The tensile strength properties of composite materials were tested by CMT6104 electronic universal testing machine according to GB/T1040-92.
The impact toughness properties of composite materials were tested by ZBC-4 balance weight impact testing machine according to GB/T1043-93.
When composite materials are collided intensely, integral stress happens in the nanofibers, thus leading to tension, fracture and extraction.

Materials play a fundamental role in any branch of civil engineering.
From ancient times to the present day, society has required enormous amounts of construction materials, which implies an excessive exploitation of materials that come directly from nature.
Once analyzed the materials, it is determined if they are suitable to be used in the elaboration of a pavement.

Fiber is one of the materials that produced a large amount yearly.
The findings of the study revealed that using biodegradable waste materials for development will transform virgin resources into sustainable materials while also lowering costs.
However, we may combine two materials to examine the efficacy and characteristics of concrete.

Take “black-headed dull” light aircraft which was self-designed by researchers of Nanchang Hangkong University as a example, the amount of composite materials used on it was reached on ninety percentage, most of the materials are carbon fiber reinforced composites.
Acoustic emissions are stress waves produced by sudden movement in stressed materials.
Second, acoustic emission detects movement of materials or structure, while most other methods detect existing geometrical discontinuities.
