Such a design leads to materials with exceptional mechanical properties over a very small density.
However, it is very difficult to dismantle composite materials in multi-material structures for recycling purposes; currently, they are mainly incinerated to produce energy.
This innovative “debonding on-demand” function provides a significant incentive to using composite materials in a circular economy, i.e. promoting the repair, reuse and recycling of these materials.
A first step towards recycling structures that incorporate composite materials is the ability to isassemble this structure into elementary parts, thereby separating composite materials both from each other, and from other adherents.

The Numerical Simulation and Parameter Optimization Analysis of Straightening Machine Straightening Process Based on ANSYS/LS-DYNA Shan Li 1,a,Yuqi Wang1,b, Liang Xu1,c 1Kunming University of Science and Technology, Yunnan ,Kunming, 650093, China akmlishan@yahoo.com.cn, bsdyuqi@126.com，cxuliang0726@126.com KeyWords: Straightening；Numerical simulation；Parameter optimization；ANSYS/LS-DYNA Abstract.Copper is important to the national economy as a kind of raw material, the Copper metal with higher purity is got by electrolysis in generally.
Fig.2 A section of copper starting sheet element model Fig.3 A section of straighening roll element model in ANSYS/LS-DYNA The problem of materal and non-linear The material of starting sheet is pure copper.
The corresponding materials parameters:Mass density(8.9e-6), Modulus of elasticity(1.1e5), NUXY (0.33), Yield stress(70), Shear modulus(48000). [5] Imposed constraints and load The rigid straightening roller has been imposed constraints before defined of material properties .The translational movement of the rigid body is constrained in three directions and two rotational displacement .Because the copper starting sheet is constrainted by positioning device in the real production process, so the displacement in the z direction can be seen as 0.The copper sheet is load into previous before copper sheet enter into straightening roller.After it go through straightening machine ,so there is the initial velocity.
