With the deep studies, CNTs Constantly show a wide range of applications in the field of emission materials, composite materials, hydrogen storage materials, electrode materials, adsorption materials, etc.[3-6] Currently, several methods have been developed to synthesize CNTs, including arc-discharge, laser ablation of graphite, chemical vapor deposition(CVD) and flame method.[7-9] CNTs synthesis using flame is a kind of novel technique.

To some extent, the CAE technology is only useful for single-material molds and will lose its function when the mold is made of different materials.
The mold material is isotropic. 3.
The mold material is 420SS .In this study, the insert is made of TOOL_STEEL(P-20) with thickness 10mm.
Second, the insert material is changed to 420SS whose λ is about 1.5 times than that of mold material.

Introduction Pipe connection fits (PCFs) (Fig.1), particularly those made of lightweight materials and had a conical sealing surface, provide excellent sealing performance, which together with their small size has made PCFs being widely used in the pipe systems of aircrafts and engines [1，2].
A PCF is a multi-body & multi-contact mechanical connection component, whose sealing performance is determined by the complicated contact states and the mechanical properties of the materials.

Materials and Methods Materials Graphite flakes (3061) were sourced from Asbury Graphite Mill Inc., while silver nitrate (AgNO₃, 98%), potassium permanganate (KMnO₄, 98%), and sodium nitrite (NaNO₂) were purchased from R&M Chemicals.
On the other hand, AgNPs or materials that release silver ions (Ag+) may have an advantage in this method.

R (the resistance of structural element) is the function of indicating mechanical property of member materials and geometrical relationship.
Failure mode of the members is similar to the proper reinforcement damage of the single-steel rectangle section beam, so the CFRP can maximize the performance of carbon fiber materials to improve the bearing capacity of members.
