Kajian ini adalah bertujuan untuk mengkaji prestasi mekanikal komposit gentingan serat semula jadi. Serat semula jadi iaitu sabut kelapa dan serat kelapa sawit telah digunakan sebagai gentingan dalam komposit berasaskan epoxi. Beberapa cara penghasilan komposit telah digunakan bagi mengenal pasti cara yang terbaik untuk digunakan bagi menghasilkan komposit dalam kajian ini. Rintangan daya hentakan oleh komposit tersebut diuji dengan menggunakan cara-cara pengujian Izod dan panduan dari ASTM D4812. Perbandingan mengenai rintangan daya hentakan dilakukan antara komposit gentingan serat semula jadi, komposit gentingan kaca dan komposit hibrid. Hasil kajian ini mendapati bahawa komposit daripada gentingan kaca adalah lebih kuat berbanding komposit daripada gentingan serat semula jadi. Adalah dibuktikan bahawa proses hibrid antara serat semula jadi dan kaca merupakan salah satu cara untuk meningkatkan kekuatan komposit gentingan serat semula jadi

The goal of this research is to explore the mechanical performance of natural fiber reinforced composite. Natural fibres which are coconut coir and oil palm fibre were used as reinforcement materials in an epoxy based composite. Several fabrication methods were used to identify the best method that suitable for composites fabrication in this research. A hydraulic compression was applied to the molds to ensure the finish composites were in desired dimension. The composites were tested for their impact resistance using the Izod testing method and ASTM D4812 standard. The impact resistance of the natural fibres composites were then compared with the E-glass epoxy composite and hybrid composite of nature fibre and E-glass. It was found that the E-glass composite is far superior to natural fibre composites. The hybridization of glass and natural fibres in a composite was proved to be an approach to enhance the mechanical properties of the natural fibre reinforced composites.
