Study on Fabrication of BMC Laminates Based on Unsaturated Polyester Resin Reinforced by Hybrid Bamboo/Glass Fibers

Abstract

Glass fiber/bamboo fiber hybrid BMC laminates were fabricated by compression molding, and their physico-mechanical properties were investigated. To improve their properties, many factors (constituent's ratio, process conditions, bamboo fiber content) were varied. The composite material reinforced with 25 wt% hybrid fibers (25% bamboo and 75% glass fibers) showed better physico-mechanical properties (tensile strength: 37.0 MPa, flexural strength: 140 MPa, impact strength: 32 kJ/m 2 ) than other combinations.

Effects of Kenaf Fiber Orientation on Mechanical Properties and Fatigue Life of Glass/Kenaf Hybrid Composites

“…The fiber volume fraction of the composites was kept at approximately 35%. The glass/kenaf weight ratio selected in this study was 70:30, which is the optimum glass/kenaf hybrid fiber composition (Dieu et al 2004;Wan Busu et al 2010;Mansor et al 2013) in a symmetric sandwich configuration.…”

Interfaces in Natural Fibre Composites: Effect of Surface Energy and Physical Adhesion

“…There was not any retting and chemical treatment applied before extracting the fibres. Vietnamese coir fibres were extracted from the husk shell of coconuts after a retting step was applied [3].…”

“…Among natural fibres, bamboo has one of the most favourable combinations of low density (1.4 g/cm 3 ) and high stiffness (~46 GPa) and strength (~800 MPa) [2]. In terms of specific properties (normalised to density), it is claimed that they can be compared with glass fibres [3]. In the case of bamboo Guadua angustifolia, it also has a high growth rate, between 11 and 21 cm per day, reaching its definitive height after 6-7 months.…”

Bamboo Fiber Processing, Properties, and Applications

“…Flexural strength of bamboo fi bers shows a significant increase on addition of amino propyl trimethoxysilane and tetramethoxy orthosilicate after alkali treatment (Lee et al 2009 ). Bamboo glass composite fi bers at bamboo to glass ratio of 1:4 show fl exural strength of 140 MPa (Dieu et al 2004 ). Bamboo fi ber reinforced cementitious plate (FRC) is found to have a very high fl exural strength, which may be upto 96 MPa (Li et al 2002 ).…”
