This paper presents the tensile properties of hybridised fire retardants Pineapple Leaf Fibre (PALF) reinforced polymer composite. The polymer composites were prepared using the hand lay-up method of fabrication, in which two-layer PALF was used, and the epoxy resin with the fire retardants were mixed. The non-hybridised fire retardants are ammonium polyphosphate (APP), magnesium hydroxide (MH) and aluminium hydroxide (ALH), while the hybridised fire retardants are ammonium polyphosphate/magnesium hydroxide (APP/MH), ammonium polyphosphate/aluminium hydroxide (APP/ALH) and magnesium hydroxide/aluminium hydroxide (MH/ALH). The samples were tested using the universal testing machine with load cell 50kN using ASTM D3039 standard. The samples APP/ALH and MH/ALH have better tensile strength, which is 37.10 MPa and 37.05 MPa, respectively. The dispersion of fire-retardants in the reinforced composites seems to affect their mechanical performance. Meanwhile, sample MH/ALH has the highest elastic modulus with 3.65 GPa. Sample MH/ALH likely to be an excellent hybridised fire-retardant filler for the composites.
