Mechanical (tensile and impact) properties of novolac type phenolic composite reinforced with jute/cotton hybrid woven fabrics were investigated as a function of fiber orientation and roving/fabric characteristics. Scanning electron microscopy (SEM) was carried out to investigate the fiber-matrix adhesion. Results showed that the composite properties are strongly influenced by test direction and roving/fabrics characteristics. The highest tensile and impact strengths and Young's modulus were found along the jute rovings direction which decreased with increasing test angle. Jute fiber exhibited a better interaction with the matrix than cotton: the former has a higher irregular surface due to its multicellular nature, which promotes a better mechanical adhesion at the interface. The combination of jute/cotton properties in this composite is suitable for lightweight structural applications. |

Consumption of foods rich in phenolic compounds can be beneficial for health. This study aimed to examine whether the consumption of a phenolic-rich smoothie, based on jucara, strawberry and banana, ameliorates metabolic status and liver damage of diet-induced obese mice. Forty male C57BL/6J mice were assigned into four groups (n = 10) and fed control diet with free access to water (C) or phenolic-rich smoothie (C-S), or fed high-fat diet with free access to water (HF) or phenolic-rich smoothie (HF-S) for five weeks. HF and HF-S groups had higher body weight gains than the C group, however the HF had a greater adipose index, higher plasma levels of glucose, insulin and leptin, as well as higher plasma and hepatic steatosis than C, C-S and HF-S groups. The liver oxidative stress markers were reduced in C-S and HF-S groups and the activity of catalase and glutathione peroxidase were higher compared with their counterparts. The present study suggests that regular consumption of a phenolic-rich smoothie improves the liver antioxidant status, prevents metabolic disorders and ameliorates non-alcoholic fatty liver disease caused by high-fat diet consumption. |
