Abstract This study involves finding the combined effect of natural fiber and synthetic for laminar structured hybrid polymer composites. The composites were fabricated using hand lay‐up technique with an unsaturated polyester resin matrix, chemically treated short Luffa (LF) varying from 2% to 8%, sandwiched between two layers woven glass (GF) (fixed amount). Physical characterizations, spectroscopic analysis, mechanical tests, thermal microscopy used evaluate performance Fourier transform infrared spectroscopy identified fiber‐matrix chemical bonding due treatment. Bulk density showed that GF increased overall density, whereas became lighter incorporation LF optimal loading at sample G/LHC3 4% decreased void formation. Water resistance higher content. Mechanical testing results revealed composite provided in tensile, compressive, flexural, impact tests values 35, 39.29, 121.65 MPa 13.38 kJ m −2 , respectively, though micro‐hardness slightly decreased. Both contributed structural integrity good adhesion. Thermal stability more GF, better insulation is achieved through These enhanced properties make promising candidates applications.

Research on biodegradable materials has gained significant attention due to increasing environmental awareness. Starch, as a polymer readily available from agricultural resources, is promising candidate for biocomposite production. Starch‐based films, though exhibiting low mechanical strength, can be enhanced using various plasticizers at elevated temperatures with shear, resulting in deformable thermoplastic material known starches. The tensile properties of these starch‐based composites further improved by incorporating fibres, making them more suitable range applications. This review highlights the significance sustainable alternatives synthetic plastics, driven concerns. It focuses natural fibre–reinforced biopolymer composites, particularly those based starch, which exhibit properties. also covers fibres reinforcement, starch component and potential applications suggests directions future research. results this compilation show that have influence characteristic fabricated composites.
