Tensile properties of sisal fibre reinforced cashew nut shell liquid composites
2008 (English)In: Futures in Mechanics of Structures and Materials: PROCEEDINGS OF THE 20TH AUSTRALASIAN CONFERENCE ON THE MECHANICS OF STRUCTURES AND MATERIALS, TOOWOOMBA, AUSTRALIA, 2-5 DECEMBER 2008, 2008, 323-327 p.Conference paper (Refereed)
Sisal fibre bundles were used as reinforcements to cashew nut shell liquid (CNSL) resin for the manufacture of unidirectional fibre composites yielding composites with fibre volume fractions ranging from 0.7 to 0.8. To improve the adhesion between hydrophilic sisal fibres and hydrophobic CN5L-formaldehydes resin matrix, sisal fibres were treated with caustic soda having concentrations ranging from 0.02 M to 0.08 M. The composite panels were tested in tension giving tensile strength and Young's modulus ranging from 104 MPa to 172 MPa and 24.54 to 33.44 MPa respectively. The specific tensile properties of sisal-CNSL composites were comparable to those where synthetic fibre such as glass fibres is used as reinforcement to thermosetting polymers such as epoxy. The use of plant fibres as reinforcement to plant based resin may be considered as a step forwards in the quest to minimize the use of fossil-fuel based resources which are energy intensive.
