Properties Of Composites

The continuous glass fiber-reinforced polyarylene ether nitriles (PEN) composites were successfully fabricated from PEN pre-impregnated glass fabric mates and PEN films using a film-stacking method. The work involved heat treatment for crosslinking reaction of PEN, and so it provided an interesting comparison of how heat treatment can influence the properties of composites. Detailed study on heat treatments for crosslinking reaction of PEN in the catalysis of the ZnCl2 at high temperature promoting the thermal and mechanical properties of composites were also investigated. The results showed that the thermal and mechanical properties of composites were enhanced by heat treatment, which is due to the fact that PEN resins could be crosslinked by the catalytic action of ZnCl2 at high temperature and formed triazine rings with a more thermally stable structure.

Refractories are used in a variety of processing industries including the ceramic, steel, aluminum, metal casting and heat treatment industries. Refractories provide thermal insulation, and do so by providing stagnant or "dead" gas space, namely, they contain a large volume fraction of voids. The prime criterion for material selection is refractoriness (i.e. use temperature) and the dimensional stability. One key property required for insulating refractory qualification is the service temperature limit (STL), which is related to composition, sinterability at use temperature, sintering temperature, and void volume. During the past ten years nano-pore and nano-scale fractal refractories have become available which are possibly significantly less toxic when compared to fibrous refractories. The materials used in fractal refractories are discussed in this article. Apart from use as high temperature thermal insulators the new class of materials are also finding use in a variety of products and applications of structural components such as nano-pore high performance coatings, sensors, filters and membranes used in the electronics, aeronautics, space, energy, and biomedical engineering fields.

This work presents an artificial intelligence based design of a series of novel advanced high performance steels for ambient and high temperature applications, following the principle of the materials genome initiative, using an integrated thermodynamics/kinetics based model in combination with a genetic algorithm optimization routine. Novel steel compositions and associated key heat treatment parameters are designed both for applications at the room temperature (ultra-high strength maraging stainless steel) and at high temperatures (ferritic, martensitic and austenitic creep resistant steels). The strength of existing high end alloys of aforementioned four types are calculated according to the corresponding design criteria. The model validation studies suggest that the newly designed alloys have great potential in outperforming existing grades.
