Abstract
The present disclosure provides a composite material layer including a core layer and a shell layer. The core layer includes foamed elastomers. The shell layer encapsulates the core layer and continuously covered surfaces of the foamed elastomers, wherein the shell layer includes a material having light absorption. The melting point of the core layer is higher than the melting point of the shell layer.
