The study of a spherically burning supplement and methods of vibropressing alumina-foam polystyrene mixtures with low molding moisture ensure immediate raw flooring, the mechanization of the main technological converters, the elimination of cropping and grinding products. The peculiarities of the physico-mechanical processes of vibropressing molding masses on the easier-forming polystyrene foam, based on the features of the macro and microstructure of the burning additive are considered.

n this research we tried to improve the thermal insulation efficiency of polystyrene foam by adding some natural materials. The gebrile soil was selected for several reasons, including abundance and ease of processing before the addition - There are many previous researches for soil treatment -. We have found at ratio 20%(The proportion of the soil in the compound) the coefficient of conduction is low and then rises after this percentage As for the absorption of water it increases by increasing the soil, but at this ratio the absorption is within the permissible limit according to the specifications required for the insulation materials and also compressive strength increase with the increasing of the soil ratio because of increasing of mechanical links between the polycarbonate and polystyrene particles and composite-material’s density increasing in general.

Composite Sandwich

Aeronautic industries, medicine, automotive industries are domains in which the composite materials are very important. In orthopedics and orthodontist domains, titanium and its alloys are very used, because their mechanical properties are similar to bone tissue. Bio-composite sandwich beams have high stiffness in flexion and good thermal characteristics. The analytical calculus for bending bio-composite beams is very important. We calculate the arrows for sandwich beams for two aspects: first – beam in four kinds of alloys (titanium alloys, stainless steel, aluminum alloys, Co-Cr-Mo alloys) and second – bio-composite sandwich beam, composed of two equal layers in same alloys and heart in: polyurethane foam, polystyrene foam, epoxide, phenolic, polyester, polyamides, balsa 1 and balsa 2 and compare its.
