Forward Logistics is defined as the manufacturers and renewable manufacturers sell raw materials, semi-finished products, spare parts to construction waste production, namely, the construction units.
In reverse logistics, the construction waste which produced by the demand side should be delivered to the third party reverse logistics provider for recycling, when building products reaches it’s design life or do not meet the design life, the own recycling building material can be sold to the demand side, and the non-recycled raw materials can be sold to renewable manufacturers for building materials production.
In this model, the third-party reverse logistics service provider has building demolition, construction waste sorting, the functions of recycling of raw materials or building materials, and providing advisory services to construction waste producers.On the upcoming demolition of buildings and structures,the third party reverse logistics service providers must identify the construction[6].

Dismantling is the first step for WEEE processing, which will mainly separate components containing hazardous substances or valuable materials.
The resource productivity equals gross industrial production of the enterprise divided by recycled material resource consumption in this year Materials improvement rate is to assess the results of performance improvement for the recycled material compared with the original waste material.

So it is of great significance to simulate the initiation and propagation of the crack in composite materials using finite element method.
In the study of composite materials crack propagation, the XFEM has been widely used.
In order to study the effect of particle to crack propagation in composite materials, XFEM was used for the simulation by Chang Ye [5].
The model shows below and it includes two materials, namely the carbon fiber and the matrix.

Since fiber reinforced thermoplastic composites are used as raw materials, on-line consolidation technique is introduced in AFP.
Automated fiber placement process In contrast to thermoset composite materials, the thermoplastic composite materials can be melted, laid down, bonded (or form) in situ, curing in an autoclave is unnecessary.
