And Chemical Properties

The accelerated aging tests under salt fog conditions were carried out on two types of composite insulators in order to evaluate their anti-aging properties. FTIR spectroscopy, hydrophobicity, and hardness measurements were taken to characterize insulator housings' physical and chemical properties before and after aging. It was found that the aging characteristics were highly dependent on housing profile, aging time, and filling materials.

The variety of kapok plants, compositions and components of kapok fiber, the fiber’s physical and chemical properties were introduced; and the product development of kapok fiber in the fields of travel, entertainment, the medium or top grade bedclothes and waddings, pillow core, back cushion and other filling materials, and also the medium or top grade garments and home textile fabrics were discussed and explored. Results show that kapok fiber is a versatile material in producing advanced buoyancy products, thermal insulation and sound-absorbing materials, and garment fabric materials.

And Chemical Properties

In connection with the spectrophotometric study of population-type characteristics of various kinds of stars, a statistical analysis of kinematical and distribution parameters of the same stars is performed at the Toruń Observatory. This has a twofold purpose: first, to provide a practical guide in selecting stars for observing programmes, second, to contribute to the understanding of relations existing between the physical and chemical properties of stars and their kinematics and distribution in the Galaxy.

And Chemical Properties

The addition of fibres or particles (TiB2, SiC etc.) into TiAl intermetallic alloys could increase their toughness without compromising their good high temperature mechanical and chemical properties. This paper briefly discribes the microstructure developed by a TiAl/TiB2 composite material fabricated with the XD™ process and forged at 960°C.The specimens for transmission electron microscopy (TEM) were prepared in the usual way (i.e. diamond polishing and argon ion beam thinning) and examined on a JEOL 4000EX for microstucture and on a Philips 400T equipped with a SiLi detector for microanalyses.The matrix was predominantly γ (TiAl with L10 structure) and α2(TisAl with DO 19 structure) phases with various morphologies shown in figure 1.

Synthesis Of Materials

Biomimetics involves investigation of structure, function, and methods of synthesis of biological composite materials. The goal is to apply this information to the design and synthesis of materials for engineering applications.Properties of engineering materials are structure sensitive through the whole spectrum of dimensions from nanometer to macro scale. The goal in designing and processing of technological materials, therefore, is to control microstructural evolution at each of these dimensions so as to achieve predictable physical and chemical properties. Control at each successive level of dimension, however, is a major challenge as is the retention of integrity between successive levels. Engineering materials are rarely fabricated to achieve more than a few of the desired properties and the synthesis techniques usually involve high temperature or low pressure conditions that are energy inefficient and environmentally damaging.In contrast to human-made materials, organisms synthesize composites whose intricate structures are more controlled at each scale and hierarchical order.
