چکیده

Abstract Novel MoAlB composites reinforced with 5–15 vol% SiC have been firstly prepared and characterized in the present study. The reinforcement is stable at a sintering temperature of 1200 °C Ar. 5 SiC/MoAlB composite exhibited improved mechanical properties enhanced oxidation resistance. A flexural strength 380 MPa Vickers hardness 12.7 GPa were achieved increased by 24% 51%, respectively, as compared those for MoAlB, indicating strengthening effect SiC. Cyclic tests 1300 10 h air showed that has better resistance than due to formation dense continuous scale composed Al 2 O 3 SiO , which prevents oxygen inward diffusion evaporation oxides. We expect general strategy second phase reinforcing materials will help widen applications composites.

Synthesis & Mechanical Characterization of Carbon/Epoxy Composites Reinforced with SiC Nano Particles

Room temperature cure epoxy resin has been doped with SiC nanoparticles through an ultrasonic cavitation process. The modified resin was then utilized in a Vacuum Assisted Resin Transfer Molding (VARTM) process with satin weave carbon fibers to manufacture nanophased composite panels. The nanoparticles were spherical in shape and about 29 nm in diameter. The loading of nanoparticles into the re...

Casting of SiC Reinforced Metal Matrix Composites

Composites based on two aluminium alloys (A536 and 6061) reinforced with 10% or 20% volume fraction of SiC particles were produced by gravity casting and a novel two-step mixing method was applied successfully to improve the wettability and distribution of the particles. The SiC particles were observed to be located predominantly in the interdendrit ic regions, and a thermal lag model is propos...
