Abstract

A wide variety of natural lignocellulosic fibers are increasingly being considered as viable alternatives to replace glass fiber in polymer composites. Jute fibers reinforced polymer composites are among the most investigated and applied natural composites. In this past decade the mechanical properties of these composites has been assessed for various types of test conditions. Owing to its low cost and weight, it may be used in many applications, including engineering composites. In fact, epoxy composites reinforced with natural lignocellulosic fibers have attracted interest in several areas, especially engineering due to its low cost, besides being lighter. The present work investigates the toughness of epoxy composites reinforced with up to 30 wt% of continuous and aligned jute fibers. Standard Izod notched specimens were impact tested and the results showed an increase in toughness with the amount of jute fibers. Observation of the composite fracture by SEM revealed that the jute fibers act as an effective obstacle to crack propagation
