Abstract
Abstract The Dynamic mechanical behavior of chemically treated and untreated hemp fiber reinforced composites was investigated. The morphology of the composites was studied to understand the interaction between the filler and polymer. A series of dynamic mechanical tests were performed by varying the fiber loading and test frequencies over a range of testing temperatures. It was found that the storage modulus (E’) recorded above the glass transition temperature (Tg) decrease with increasing temperature. The loss modulus (E”) and damping peaks (Tan δ) values were found to be reduced with increasing matrix loading and temperature. Morphological changes and crystallinity of Composites were investigated using scanning electron microscope (SEM) and XRD techniques. The composites with Alkali and Benzoyl treated fibers has attributed enhanced DMA Results. In case of XRD studies, the composites with treated fibers with higher filler content show enhanced crystallinity.
Highlights
Manufacturing high performance engineering materials applications in interior panels, linings and fittings
These results suggest that cellulose in raw Hemp fiber is held together by means of binding components such as lignin, pectin, etc, which are removed after treatments
The storage and loss modulus decreased with the increase in temperature, which is associated with a softening of the matrix at higher temperatures
Summary
Manufacturing high performance engineering materials applications in interior panels, linings and fittings. It is from renewable resources is one ambitious goal currently an important step towards higher performance of hybrid being pursued by researchers across the world. It is reported benefits of renewable raw materials are clearly saved valuable that presently, 27 components of a Mercedes S class are resources are environmentally sound and do not cause manufactured from natural fibre based composites with health problems. Previous studies carried out an improvement on dynamic mechanical properties have proved hemp fibers to be an effective reinforcement of different polymeric composites system. The comparative in polymer matrix[5]
