The results showed that the mechanical properties and UPF of PET fiber have been improved due to the introduction of nano-TiO2 particle into PET substrate. The tenacity of composite fiber can amount to 3.76 cN/dtex and the UPF of fibers among 290nm to 400nm wavelength has been greatly strengthened.
Colligating polyphase recombination,SHS technology,in-situ synthesis technology,high temperature insostatic pressing technology and metal phase adding tenacity etc,so TiB_2/Al_2O_3 composite holds high strength and moderate tenacity.
This paper has studied the making method of in-situ forming TiC particle as a emphasis to reinforce the ZA43 composites, observed and investigated the metallographic microstructure and dynamic properties, include the impact tenacity, hardness, strength, ductility, wear resistance, tensile strength and ductility at high temperature.
The result demonstrate that compared with TiC particle as a emphasis to reinforce the ZA43 composits and ZA43 matrix ,its tensile strength . hardness ,wear resistence and the strength at high temperature all increased at some degree,but its impact tenacity and ductility reduced.
The G/C is isotropic, has a density of 1.85g/cm3, and has a higher volume resistivity (148.4μΩ·m) than graphite and the other C/C composites. It has excellent mechanical properties with a flexural strength of 50MPa and a compressive strength of 120MPa, twice those of pure graphite.
An experimental investigation of the failure of selected compression-loaded [0°]48, [±30°]12s, [±45°]12s , [±60°]12s, [90°]48 Graphite/Epoxy composite laminates is described. The experiment results include compressive strength data and description of laminate failure modes and failure mechanisms.
The compressive strength of the composite is higher than that of the PLA scaffold.
Fracture energy of Mode I (opening mode) for the Ordinary and Low-Heat Concrete is compared and examined according to experimental variables, such as water-cement ratio, compressive strength and age.
In the depressed front regions (bubbles), the medium probably exhibits a certain densification and the resulting compressive strength hinders the bubble growth in the initial stage of instability development.
Compressive strength exhibited the similar behavior with density.
Research results show that there is a negative linear relationship between the Si 2p and Al 2p binding energies of Al-Si materials and the compressive strength of aluminosilicate based cementitious materials prepared with these Al-Si materials, i.e.
