Abstract
:1. Introduction
2. Materials and Methods
2.1. Experimental Process
- (1).
- β-SiC weight ratio: This indicates the weight ratio of β-SiC mixed with PU, with S50 meaning 50:50.
- (2).
- Weight ratio of added MWCNTs: C00 means that no MWCNTs were added, C05 means that 0.05% MWCNTs were added, C10 means that 0.10% MWCNTs were added, C15 means that 0.15% MWCNTs were added, and C20 means that 0.20% MWCNTs were added.
- (3).
- Composite thickness: T1 means 1 mm thickness, and T2 means 2 mm thickness. For example, the sample number S50C15T1 means a wave-absorbing composite with a β-SiC-to-PU ratio of 50:50, 0.15% MWCNTs added, and a thickness of 1 mm.
