Evaluation of Izod impact and bend properties of epoxy composites reinforced with mallow fibers

Autor: Ulisses Oliveira Costa, Lucio Fabio Cassiano Nascimento, Julianna Magalhães Garcia, Wendell Bruno Almeida Bezerra, Sergio Neves Monteiro

Publikováno v: Journal of Materials Research and Technology, Vol 9, Iss 1, Pp 373-382 (2020)

Epoxy composites reinforced with 10, 20 and 30 vol% of a natural lignocellulosic fiber, the mallow fiber, were investigated for mechanical properties associated with Izod notch toughness and flexural resistance. For Izod tests, 150 × 120 × 10 mm pl
