The morphological, mechanical, and physical attributes of novel hybrid epoxy polymers reinforced with fibres from camel's foot and doum palm, treated with alkali, have been carefully investigated. FTIR spectroscopy demonstrated the efficacy of the NaOH treatment by the partial elimination of non-cellulosic constituents, evidenced by an upward shift in the O–H excitation peak from 3297.30 to 3323.28 cm-1, along with a reduction in the C–H and C=O bands. The mechanical evaluation demonstrated that hybridization significantly enhanced performance, achieving an ultimate tensile strength of 41.67 MPa and a tensile modulus of 3.459 GPa at an optimal filler ratio of 4.0D to 1.0P. This optimal ratio was validated by SEM morphological analysis, which showed reduced gaps and improved adhesion between fibres and the matrix. Composites maintained a low density of 0.96-1.27 g/cm3 and absorbed minimal water (up to 2.07%). The results indicate that the two natural fibres effectively combined to produce a composite material with enhanced mechanical strength and significant potential for use in environmentally friendly construction and vehicles.
