When composite materials and structures consist of two or more different materials periodically, there will be stop band characteristic, in which there are no mechanical propagating waves.
The physical properties of PCs are not essentially determined by chemical elements and bonds in the materials, but rather on the internal specific structures.
They are created by arranging periodically two or more materials with different vibrational properties.
Acoustic band gaps in fibre composite materials are studied in [2] and band structures are calculated for 2D binary solid/solid composite systems.

But most of them were based on the sensitivity from designer’s subjectivity to fashion not on the science foundation.
Esigning Experiment FOR Achieving And Analyzing Body Data In order to achieve data and make research from materials collected, first it was necessary to confirm a module for fashionable variables achieving [1], which was uniform variable that its difference among different individual was the lest and it was convenient for achieving fashionable variables.
Achieving Fashionable Variables Data In computer by PHOTOSHOP software, data of fashionable variables were achieved with photo materials.
Conclusion Based on the photo materials and data achieved, the fashion trend and anticipating was discussed and the open fashion historical database of woman warm jacket was developed.

The ordinary method is packaging with polymer material in axisymmetrical structure [7].
But the pressure sensitivity is still not high enough because of the property of the polymer material in this method.

Another accepted method of the composite materials manufacturing is the in situ synthesis method.
A considerable part of such materials are composite materials based on aluminum or its alloys with a unique combination of physical and mechanical properties [1, 2].

Introduction Natural materials are characterized by low cost compared to other engineering materials [1,2].
Natural materials do not have sufficient properties that distinguish them from industrial materials, so resorting to Combining them with other materials to improve their properties by adding them as fillers or reinforcing materials to form composite materials, especially with polymers [9].

Laser machining, a green process developed at Cirrus Materials Science Ltd, generates an array of pores on various polymer surfaces, which replaces the chemical etch process, and provides strong adhesion for metal coatings to polymer substrates.
Laser machining employs a pulsed laser to remove materials from a substrate, so that micro or nano structures can be produced on the surface.
