Abstract Specimens prepared from yacon roots in first two weeks after harvest were tested by dynamic mechanical analysis thermal analysis at temperatures between 30 and 90°C. No differences between different parts of roots were proved. There were indicated some differences in the test parameters that were caused by short time storage of the roots. One source of the differences was loss of water during the roots storage. The measured modulus increased during short time storage. Detailed study of changes of the modulus during the specimen dynamic mechanical analysis test provided information about different development of the storage and loss moduli during the specimen heating. The observed results can be caused by changes in cellular membranes observed earlier during vegetable heating, and by composition changes due to less stable components of yacon like inulin.

In present investigations, dynamic mechanical thermal behaviours of Arenga Pinnata fibres prior and after alkaline treatment were studied. The alkaline treatments were applied on the Arenga Pinnata fibres by immersed in the alkaline solution, 6% Sodium Hydroxide (NaOH). Using hand lay-out technique, composites were fabricated at 20% and 40% by Arenga Pinnatafibres weight contents. The thermal behaviours of both untreated and treated composites were determined by employing Dynamic Mechanical Analysis (DMTA). The results shows that the treated fibres owned better results of Storage Modulus (E’), Loss Modulus (E”) and Tan Delta temperatures ranges from 0°C to 80°C
