Tensile strengths, values

Properties. Properties of stmctural siHcon nitride ceramics are given in Table 2. These values represent available, weU-tested materials. However, test methodology and the quaHty of the specimens, particularly their surface finish, can affect the measured values. Another important material property is tensile strength. Values obtained on Norton s NT154 material are 750 MPa at RT, 500 MPa at 1200°C, and 350 MPa (50,000 psi) at 1400°C (62).

Likewise, the mechanical properties of the copolymers were nearly identical or even somewhat enhanced towards the polyimide homopolymer in terms of the modulus and tensile strength values [44,47]. For most of the block copolymers, the elongations to break were substantially higher than that of PMDA/ODA polyimide (Table 4). The shape of the polyimide stress-strain curve is similar to that of a work-hardened metal with no distinguishable yield point... 

Figure 10.9. Peak room-temperature tensile strength values of the interfaces formed by AI2O3 with sessile drops of Ni or Ni-metal M alloys plotted as a function of the standard Gibbs energy of formation of M oxide, (Crispin and Nicholas 1976). Full circles Ni alloys hollow circle Ni from...

A statistical analysis of the liber tensile strength values determined on a series of fiber samples can be easily made by using the two-parameter Weibull distribution described above. Using the form of the Weibull expression given in Eq. (10.2), we can write the probability of failure F(o) of the liber at a stress a, as... 

It is said that the newspaper hemi-spheres are the most suitable for shell manufacture. (At present they are not used for export, but only for the shells displayed in Japan.) The reason is that they have a moderate tensile strength and they split more uniformly than the straw board spheres. The tensile strength value of newspaper generally sold in Japan is abput 70 80 kg/cm in parallel and about 5 kg/cm in vertical, which is 1/3 of the Japanese Kozo paper. A sphere is manufactured by pasting... 

Glasses are purely elastic bodies at room temperature with elastic moduli between ca. 50 and 90 kN/mm. The flexural strength and tensile strength values (between 10 and 100 N/mm ) depend upon the quality of the surface. 

MWCNTs in the PFSA resin. Compared to the recast Nafion membranes, both stretching and tensile strength values were greatly improved (by 27% and 54%, respectively). A comparison ofthe mechanical properties and electronic conductivity showed the optimum MWCNT content to be approximately 3 wt%. 

There is only one hint in the literature, by Starkweather (10), that deals with copolymerization with butadiene. The polymers described there have poor tensile strength values and elongations.
