WebThe specimens were exposed to 80 °C hot water to investigate the hydrothermal aging behavior. For the water absorption properties, the weight gain and weight loss of GF/PP barely changed after 1600 h. The weight of GF/POM increased within 25 h, and then reached equilibrium. After 1600 h, the weight loss of GF/POM was below 0.4%. WebAug 1, 2013 · The high moisture and water absorption rate of kenaf fiber-reinforced POM composites was due to the presence of a natural fiber that is generally hydrophilic in nature. The kenaf fibers are prone to moisture and water absorption due to the presence of constituent materials such as cellulose and hemicellulose. b j thomas hey won\u0027t you play
