The present invention provides a glossy finish sandwich composite, comprising face sheet as skin element and a core element; wherein, the skin element is a composite selected from the group consisting of inorganic industrial waste particulates reinforced polymeric composite; fibres reinforced polymeric composite; and fibres and particulate reinforced hybrid polymer composite; wherein, the core element is selected from the group consisting of polyurethane foam and wastes reinforced polymeric material. The present invention also provides a novel process for developing glossy finish high performance hybrid sandwich composite(s). Moreover, the sandwich composite(s) of the present invention are unique materials which have versatile applications in wider spectrum of utility in sustainable manner and address issues on waste management, effective utilisation of renewable resources and agro-wastes.

Process for making a glossy finish sandwich composite

The present invention deals with development of a novel process for manufacturing moisture resistant glossy finish hybrid green polymeric composites with variable density in range of 0.2-1.68 g/cc, low water/moisture absorption in the range of 0.1-1.3%, tensile strength and tensile modulus in range of 6.5-105 MPa and 250-6850 MPa, respectively and to the best of our knowledge the fabricated hybrid green composites has not yet developed universally using different types of industrial wastes particulates. Moreover, hybrid composites developed using industrial wastes, natural fibres and epoxy/polyester/polyurethane polymers is a unique materials and have multifunctional applications in wider spectrum as an alternative to wood, synthetic wood, wood plastic composites, screen printing sheet, plastic, fibre and glass reinforced polymer products, including tin sheet.
