Interfacial Shear Stress in Kenaf/Polyethylene Terephthalate Fiber Reinforced Polyoxymethylene Composite

Abstract:

The mechanical properties of fibre reinforced polymer composites strongly depend on the interfacial bonding between fibre and matrix. The main objective of this paper is to compare the interfacial bonding between kenaf fibre reinforced POM with that of PET fibre reinforced POM in a hybrid composite. Continuous twisted kenaf, and PET yarn were used for the investigation. Each fibre yarn was half embedded in POM by compression moulding. The yarns were extracted from the matrix by single fibre pull out test method. The result of the investigation revealed that the interfacial shear strength of approximately 31.4 MPa between kenaf and POM is higher compared to 24.3 MPa obtained between PET fibre and POM. This may be due to higher surface energy of kenaf fibre with respect to POM in the composite The FESEM micrograph further demonstrates good interfacial adhesion between kenaf and POM in the composite.
