Influence of fiber length, fiber content and alkali treatment on mechanical properties of natural fiber-reinforced epoxy composites (in English)
Polimery 2019, No 2, 93
The composites of epoxy resin and Cocciniaindica fibers (CIF) were obtained. The raw fibers were initially treated with 5 % NaOH. Compression molding technique was used for preparing the composites with four different fiber lengths (10, 20, 30, 40 mm) and various fiber loadings (25, 30, 35, 40 wt%). The mechanical properties of the produced composites were investigated and their structure was analyzed by using scanning electron microscope (SEM). It was found, that the composite matrix reinforced with 30 mm fiber length at 35 wt % fiber loading exhibited the best mechanical properties.
