Toughening of ceramic shell mould with rice husk fiber (CSm-RH) to improve strength property and mould performance
For ages, ceramic shell mould (CSm) have been extensively applied in investment casting industry. The formation of CSm requires multiple steps of dipping, layering drying and firing stages. The later steps are very crucial as the solidification thin layer CSm that consist of loose ceramic partic...

| description | For ages, ceramic shell mould (CSm) have been extensively applied in investment casting industry. The
formation of CSm requires multiple steps of dipping, layering drying and firing stages. The later steps are very crucial as
the solidification thin layer CSm that consist of loose ceramic particles easily cracks when exposed to the higher thermal
effect. The inclusion of fiber or any reinforces phases is able to enhance fired ceramic body and also strengthen the green
ceramic structure. Thus, the feasibility of rougher NaOH treated rice husk fiber (RHT) prior embedded into composited
structure has shown a significant CSm improvement by induced a better adhesion properties and larger bonding area with
brittle ceramic matrix, resulted in increased green strength (1.34 MPa) and fired body strength (4.32 MPa). Owing to the
decomposed of lignin layer in CSm with untreated rice husk fiber (CSm-RHU) exhibited a higher porosity that provide
a better permeation paths of air flow during molten metal pouring as increased 30 % from the standard CSm permeability,
giving an enormous benefit for investment casting cooling process. Overall, the incorporation of RHT fiber in a CSm
matrix of both green and fired body governed in toughening of brittle ceramic body, hence avoid failure to the casting
mould. |
