“…Due to the pullout effect of the Al-Si alloy these biomorphous ceramics showed graceful failure behaviour. The rattan derived biomorphous SiSiC/Al-Si composite showed an average strength of 200 MPa, which is in the same order of magnitude as conventionally prepared SiC/Al-Si composites [38].…”

The generation of biominerals and hard tissue in nature is directed and templated by biomacromolecules. In many systems, polysaccharides play a significant role during the assembly of the inorganic phase. Polysaccharides exhibit a hierarchical multiscale order as well as self-assembly properties and they appear in a large variety of structures. The directed deposition of inorganic phases on polysaccharide templates is an interesting approach for the manufacturing of patterned functional materials. This paper highlights our recent developments on the bioinspired deposition and formation of inorganic phases on polysaccharide templates. Polysaccharides can be used at various structural levels from the molecular scale to three-dimensional parts in the millimetre range. The versatility of polysaccharide templating capabilities will be shown on onedimensional cellulose nanocrystals for formation of luminescent inorganic nanotubes for optoelectronic applications. The replication of complex plant tissue and processed lignocellulosic materials such as paper and cardboard into carbide based engineering and functional ceramics will be presented. The developed methods for the mineralisation of inorganic phases on polysaccharides are adapted for an innovative bioinspired route involving phototactic microorganisms, which are useful for the light-induced fabrication of hierarchically structured functional materials.

“…The resulting material is a SiSiC/Al-Si composite. Exemplarily, we extended our method to a complex form made from cardboard, figure 4d) [38]. The biomorphous structure revealed a high amount of plastic deformation before the final failure.…”

“…The use of Al MMC with a high specific E leads to a significant weight reduction. Conventionally, stiffening phase in Al MMC with high E is introduced ex-situ typically as ceramic particulates, wherein SiC is the most popular because of its relatively high E and strength, good availability and low price [5,6]. Traditional ex-situ Al MMC suffer from the problematic introduction of reinforcement, the damage of reinforcement and undesired interfacial reaction [3,7].…”

The study demonstrates a high-temperature wear of extrusion die during hot pressing of in-situ and ex-situ Al metal matrix composites (MMC). The in-situ Al-10.5vol.%AlN and ex-situ Al-10.5vol.%SiC with high Young's modulus are fabricated by powder metallurgy approach. The composite microstructure and the mechanical properties are characterized. Die wear during hot extrusion of MMC is quantified by the increase of radius of a worn edge as a function of the distance of extruded bars. In-situ Al-AlN exhibited a significantly lower abrasive effect in addition to higher mechanical properties compared to ex-situ Al-SiC.

“…The tribological behavior can be evaluated in terms of wear characteristics. The wear characteristics of these alloys depend upon the material morphology such as composition, size, shape and distribution of reinforcements and service conditions such as load, contact surface, contact time and sliding speed [14][15][16][17][18][19][20][21][22]. The effect of process parameters and the addition of reinforcement on the dry sliding wear of the composites were investigated vastly and explained that incorporation of hard secondary constituent in the matrix significantly improves the wear resistance.…”
