Title: Innovations by Denis Bijaoui in Tire Technology
Introduction
Denis Bijaoui is an accomplished inventor based in Bangkok, Thailand. He has made significant contributions to the field of tire technology, holding 2 patents that showcase his innovative approach to designing tires for heavy loads and civil engineering vehicles.
Latest Patents
One of his latest patents is for a tire designed for vehicles carrying heavy loads. This tire features a tread band with a plurality of grooves oriented transversely. It is composed of three distinct rubber materials, each with specific properties to enhance performance. The first material, located in the median part of the tread band, has a secant modulus at 10% elongation of at least 4.0 MPa and hysteresis losses greater than 0.19. The second material, found on the edge parts, has a lower secant modulus and hysteresis losses of at least 0.15. The third material, positioned radially below the first two, has hysteresis losses lower than 0.12. Notably, the first material exhibits a resistance to wear that is at least 15% better than the other two materials.
Another significant patent by Bijaoui is for a tire tread specifically designed for civil engineering machinery. This tread includes a central part defined by circumferential grooves, with lateral parts featuring a plurality of transverse grooves that create blocks. The tread is characterized by channels extending transversely under the tread surface, which open into the circumferential grooves and at least one transverse groove of the shoulder parts. Each channel has a cross-sectional area that is at least 5% of the minimum cross-section area of the transverse groove into which it opens.
