This research investigates the effects of particle size and weight percent on the hardness of A356 matrix composite reinforced with SiC particulates produced by semi-solid stir casting. The particle sizes of the reinforcing phase were in the form of 37 and 100 μm SiC powders with loading content of 5, 10, 15 and 20 percent by weight. A356 alloy was melted and SiC powder was then gradually added into the continuously stirred slurry to promote uniform distribution of the particulates. It has been found that in the as cast condition, the average hardness values of A356 reinforced with different amounts of 37μm SiC, increase as expected with increasing amounts of particulates. A356 reinforced with 100 μm 10 wt% SiC, followed by T6 treatment, exhibited the highest percentage of hardness increment.

A 2 × 3 factorial arrangement of treatments was used to investigate the effect of grind size and blend ratio on quality and sensory traits of restructured pork manufactured from hot-processed sow meat. Two blend ratios: [1. 50% through a 3.2 mm plate (FG)/50% tenderized muscle chunks (TMC); 2. 40% FG/60% TMC] were used in combination with three different sizes of TMC. The TMC portion was prepared by: grinding once through a kidney plate (K), grinding twice through a kidney plate (KK), or grinding once through a kidney plate followed by grinding through a 10 mm plate (K10). The six treatments were: 50FG/50K, 50FG/50KK, 50FG/50K10, 40FG/60K, 40FG/60KK, and 40FG/60K10. There were no differences (P>.05) for cooking loss, juiciness, connective tissue, or flavor scores; however, restructured steaks from the 40FG/60K treatment were more cohesive (P<.05) than the steaks from the 50FG/50KK, 50FG/50K10, and 40FG/60K10 treatments. Restructured steaks from the 40FG/60K treatment had greater shear values (P<.05) than steaks from the 50FG/50KK treatment which had greater shear values (P<.05) than steaks from the 50FG/50K10 and 40FG/60K10 treatment. Restructured steaks from the 50FG/50K10 treatment had greater tensile strength (P<.05) than those from the 50FG/50KK treatments. It was determined that a 50% chunks/50% fine ground blend ratio in combination with any of the three grind sizes would be best suited for use in commercial processing operations. This ratio is the more practical ratio to obtain from the sow carcass, and no added product quality is achieved by the use of a 60% chunks/40% fine ground ratio.

Recently, owning to the increasing concerns on the environment, lightweight materials representative by composite are being considered to be used in primary structure components in particular in vehicle instead of metal. In order to enhance the mechanical property in particularly tensile property, at current study, stampable sheets (glass mat which were fabricated by punch knitted technology) were adopt to make glass mat reinforced thermoplastic PP (GMT). In the paper, three kinds of specimens including two GMT which have glass fiber weight percent 40 and 20 wt% respectively and a LFT (normal long fiber reinforced thermoplastics PP) which has glass fiber 40wt% were fabricated and tensile tested. The mean fiber length of GMT and LFT were 6.67 and 1.37 mm, respectively. For tensile test, it was observed that the modulus of 40GMT and 40LFT were similar. However, it was found that 40GMT specimens have better tensile strength than 40LFT specimens. In the case of different glass fiber content, 40GMT had more than two times higher value than 20GMT in both tensile modulus and tensile strength. Referring to the effect of hole on the tensile property of GMT and LFT, it was found that the notched tensile strength of both GMT and LFT decrease when W/d equal to 2.0. On the other hand, for W/d equal to 2.5 and 3.0 have no effect to tensile strength.
