Abstract:

The use of cellular foams as a core material in light-weight optical and structural systems is of considerable interest. Research and development of these systems, however, have been hampered by the lack of material property data and uncertainty in the use of various suggested material characterizations and the associated constants of proportionality. ASTM standards were researched and, for the most part, found inadequate for testing cellular foam materials. The compression, tension and shear test methods developed are presented, as well as the results from physical tests on closed-cell SXATM

Abstract:

The use of cellular foam as a core material in light-weight structural applications is of considerable interest. However, advances in this technology have been limited due to the lack of information concerning the macroscopic material behavior of cellular foams. Of particular interest in the design of composite structures is the shear modulus, G, of the core material, which must be established with a high degree of accuracy. Current ASTM test methods for shear modulus determination were researched and found inadequate for testing cellular foam materials. The difficulty in testing foam and the

Foamed bitumen treated material has been used with success in many countries around the world. Regardless of the success story, it is also true that there is a dearth of knowledge concerning the understanding of the effect of the current used compaction

Abstract:

Supercritical CO2 foam processing of biopolymers represents a green processing route to environmentally friendly media and packaging foams. Mater-Bi, a multiconstituent biopolymer of polyester, starch and vegetable oils has shown much promise for biodegradation. The polymer, however, is not foamable with CO2 so blended with another polymer which is. Polycaprolactone is a biopolymer with potential of 4000% change in volume with CO2. Thus we investigate blends of Mater-Bi (MB) and polycaprolactone (PCL) foamed in supercritical CO2 using the batch process. Characterization of the foamed and unfoa

Due to the rising demand of light-weight constructions as well as the conservation of resources, the density and weight of thermoplastic parts could be influenced significantly by using the thermoplastic foam injection molding process. The structure of the foam injection molded part, which typically means solid surface layers and a cellular core, usually results in a weight saving. Furthermore the materials structure leads to an increasing of the specific bending stiffness with a simultaneous low tendency to warp.

Abstract:

Excessive fluid-borne noise in hydraulic systems is a problem the fluid power industry has long struggled to address. Traditional noise control devices such as Helmholtz resonators, tuning coils, and Herschel-Quincke tubes are generally too large for fluid power systems unless the speed of sound in the device can be reduced. A compliant lining can achieve this effect, but compliance (and lossy compliance) has had little attention in noise control in general, and in fluid power in particular. One means to achieve compliance in these devices, especially at elevated pressures, is through a liner

The use of fibers is a viable solution to partially overcome the brittle behavior of such materials. At the same time it is demonstrated that fibers, by reducing cracking phenomena, allow to face the durability related issues.
