M40/epoxy 648 composite materials with epoxy 648 boron tri-fluoride monoethylamine as resin matrix material reinforced by M40 graphite fiber has become one of the Principal construction materials widely used in China's applications satellites.
According to the principle of stress measurement by X ray diffraction, the test method of matrix yield strength in composites was established The actual yield strength of matrix in a 20vol%SiCw/Al composite was measured The results show that, the matrix yield strength in the composite is obviously higher than that of single matrix material The matrix strengthening in the composite is mainly due to high dislocation density and fine sub gain
In this pater,glass-ceramic matrix material which may be well matched with SiC fibre wasstudied. Adapting a tailor making method of preparation,Li_2O-CaO-Al_2O_3-SiO_2 system glassmixed with MgO as an additive was sintered.
本文研究了在 Li_2O-CaO-Al_2O_3-SiO_2(简称 LCAS)玻璃中加入 MgO 添加物,用烧结方法制备成适合于 SiC 纤维相复合的微晶玻璃基质材料.
In order to determine the depandance of matrix material performance of electroplated diamond bit on the bath composition and operating parameters, in this paper orthogonal design method was adopted to study the effects of the concentration of Ni 2+, the concentration of Co 2+,the pH value of plating solution and cathodic current density on deposit's wearing resistance.
Effects of normal pressure on the friction coefficient were investigated for the dry sliding system of SiC particulate reinforced 6061 aluminum composite against carbon matrix material, on the self manufacture block on disc type high speed friction tester, under sliding velocity 30 m/s and normal pressure from 0.1 MPa to 0.8 MPa.
The effects of the matrix material (agar and calcium alginate gels, ceramic support, and cellulose powder) on the biosensor signal concentration dependence, detection time, and biosensor stability were studied.
The two-dimensional problem of the propagation of an impurity in underground flows is investigated with allowance for chemical reactions between the solvent and the ore-bearing matrix material.
Cesium and strontium are immobilized through solid-phase crystallization at temperatures below the softening point of the matrix material (at 700-900° C).
Geoconcrete monolith as stable matrix material for immobilization of radioactive wastes
It is shown that increasing the band gap of the matrix material makes it possible to increase the localization energy of quantum dots relative to the edge of the matrix band, as well as the states of the wetting layer.
