Ceramic foam are a class of high porosity materials that are used for various applications. In this study, foam ceramic porcelain powder was produced by using polymeric sponge replication method at different solid content ranging from 30 to 50 wt. %. Properties of ceramic foam was characterized for porosity and density. Ceramic foam then grafted with methyltriethoxysilane (MTMS) at different concentration ranging from 0 to 9.0% v/v to determine hydrophobic effect and oil absorption capacity. From the results, it was found that the density of ceramic foam increased while porosity was decreased with increasing solid contents. It is clearly seen that, MTMS grafting contribute to hydrophobic effect of ceramic foam which enable repelling of water. The amount of oil absorbed by ceramic was found increased by increasing concentration of MTMS for all solid contents. As conclusion, MTMS give significant effects on hyrdophobic ceramic foam and produce good absorption capacity. The lower solid content produced better oil absorption compared to higher solid content due to presence of higher porosity.

A tubular ceramic support intended for use in transesterification process was prepared using the polymeric foam replication method. Pieces of foam with pores 120 ppi in size were completely immersed in a 25wt% solid-loading of porcelain slurry. The dried samples were sintered for 2 hours to temperatures ranging from 1200?C to 1265?C, respectively. It was found that the optimum sintering temperature was 1250?C as the following values were obtained for each characteristic: 1.98 MPa compressive strength, 47.3% porosity, 2.773gcm3 density and 0.45mm pore size. XRD results show that the sintered ceramic consists of mullite and quartz.

This paper studies the effect of various polymeric foam template densities and solid loadings on the properties of ceramic foam. The study was based on six different polymeric foam templates with densities ranging from 13.4 to 37.8 kg/m3. The templates were impregnated in ceramic slurry with solid loading ranging from 15 to 60 wt. %. Effects of polymeric foam template density and solid loading quantity were evaluated based on porosity, density and mechanical properties of resulted ceramic foam. It was found that the density, porosity and flexural strength of ceramic foam seem to be independent from the template densities when the solid loading is less than 35 wt. %. For the given solid loading, i.e < 35 wt. %, the density and flexural strength are less than 1100 kg/m3 and 6 MPa, respectively, and porosities are higher than 40 %. The polymer replication method is a versatile method for the production of ceramic foams. It will allow the production of any desired properties of ceramic foam through a simple modification route.

This paper shows the applicability of a non-linear Finite Element (FE) methodology to analyse the elasto-plastic behaviour and the energy absorption of a padding noise-protection material applied to the vehicle interior components. This material is a sandwich built from alternating layers of polymeric foam and of glass fibre composite. The approach considers two design steps. The first one involves the experimental characterization of the material while the latter deals with the assessment of the numerical models validated for a full-vehicle crash analysis.
