Improvement in tensile property of the hybrid was achieved with the result showing a direct proportionality relationship between tensile properties and increasing radiation dose. Statistical analysis software (SAS) was employed to validate the result. HDPE has been shown to have self-cross-linked, enabling interesting tensile properties with irradiation. Statistical analysis validated the results obtained and also showed that adequate mixing of fibres and matrix had taken place at 95% confidence level. Hybridization and subsequent irradiation increased the tensile strength and modulus of HDPE up to 31 and 185%, respectively, at about 100kGy. Meanwhile, SEM was used to view the interaction between the fibres and matrix.

Sapuan) *Corresponding Author INTRODUCTION For many years, research has been carried out on the use of natural fibres for both automobile and structural applications. This has helped to reduce the use of synthetic materials for the sake of our environment. Nowadays, natural fibres are used to reinforce polymers that serve as matrix. Several factors have aided the
