主　　题：Microwave welding Silicon carbide Nanowhiskers Joining Susceptor 

摘      要：Due to their excellent dielectric properties and the rapid response to microwave irradiation,silicon carbide nanowhiskers(SiCNWs)were employed as microwave susceptor in this study to absorb microwave and locally melt the surrounding polypropylene(PP)substrates for the joining of PP *** welded joint is formed after the melted PP was cooled and *** than microwave susceptor,SiCNWs also acted as the nanofillers in strengthening the welded joint through the formation of SiCNWs reinforced PP nanocomposite at the interface of PP ***,the effect of microwave power on the microwave welding of PP substrates using SiCNWs as susceptor was studied and *** was found that the tensile strength and modulus of elasticity of the welded joint improved as microwave power ***,it deteriorates the flexibility of the welded joint as high stiffness SiCNWs were incorporated deeper into the PP matrix which restricted the PP chain *** from microwave power,clamping pressure is also critical in determining the mechanical properties of a welded *** compared to unclamped welded joint,the tensile strength,modulus of elasticity and flexibility of welded joint subjected to clamping pressure improved ***,the tensile strength of welded joint increased when the clamping pressure was increased from P1 to P3,but decreased when the clamping pressure was further increased to P4 due to the occurrence of flashing at welded *** formation mechanism of SiCNWs reinforced PP welded joint was also proposed in this *** to conventional welding,this welding process is easy,straightforward and is able to produce welded joint with outstanding mechanical properties via precise controlling of the processing ***,microwave welding is thought to offer an option for the joining of thermoplastics and other applications.
