Introduction Ultra High Molecular Weight Polyethylene (UHMWPE) is polymer materials of high strength, high wear resistance and low friction coefficient.
But because UHMWPE’ surface is inert and non-polar and at the same time highly oriented and crystalline, UHMWPE’ surface wetting is poor and has the very poor bonding properties with other materials. 45# steel has high surface energy and good adhesive properties.
Because the surface properties of UHMWPE is very different with 45# steel, how to bond the two materials is a quite difficult problem.
Experiment Materials Chloroprene rubber A-90 (CR) was provided by Japan NEC Chemistry.

Generally speaking, dielectric permittivity (ε) and magnetic permeability (μ) are both positive for natural materials.
A sharp dip, as in left-handed materials, was observed.
As for low-loss materials or LHMs, small errors or noise may cause when the reflection coefficient is close to zero [24].

Introduction With the development of the science and technology and the civil engineering industry, concrete will still be the main building materials in the coming period.
High performance concrete consists of high quality raw materials with modern technology and meets the requirements of building and construction.
Materials Cement: P · O 42.5 cement, its performance index is in Table 1.
(5) Conservation conditions and age Von Fay etc. (1993) studied the freeze resistance of fly ash concrete in different curing conditions and different amount of binding materials.
The results showed that the wet curing was conducive to frost resistance of fly ash concrete, and frost resistance improved significantly with the increase of cementitious materials.

This equipment enables fatigue evaluations on both materials and components and complies with standards such as DIN 50100 for S/N curve generation in tensile, compressive, and alternating stress regimes.
