Abstract

This study was carried out to compare the functional properties of cores produced using linseed oil (LO) and rubber seed- Shea butter hybrid oil (RSSBHO) as binders. Hybrid core oil made of 50% of rubber seed oil and 50% of Shea butter oil was prepared. Core sand mixtures containing oil content of 0.5, 1, 1.5, 2, 2.5 and 3% were prepared using linseed oil and the hybrid oil, separately. Various specimens were then prepared from the core sand mixtures and tested for green and dry compression strengths, green and dry tensile strengths, green permeability and collapsibility. Maximum strengths of the cores were obtained for both oils at 3% oil content. For cores bonded with hybrid oil, 40 kN/m2, 625 kN/m2, 36.33 kN/m2, 591 kN/m2, 410.67 and 166.67 s were obtained for green compression strength, dry compression strength, green tensile strength, dry tensile strength, permeability number and collapsibility, respectively while for those bonded with linseed oil the values were 38 kN/m2, 634 kN/m2, 35 kN/m2, 604.67 kN/m2, 421.67 and 170 s, respectively. T-test analysis showed that the properties of the cores produced from hybrid oil are statistically equal to those of cores produced from linseed oil at p>0.05 and are within the acceptable standard values. Therefore, hybrid RSSBHO can be used to replace linseed oil in the production of cores for aluminium alloys, copper bronzes, copper brasses and iron and steel castings.
