Mathematical Model with Actual Conventional and Modified Composite Boards

Verification of the Mathematical Model with Actual Conventional and Modified Composite Boards 

A die was made, and the modified board (Figs. 7.17, 7.18, and 7.20) was extruded using the same HDPE filled with rice hulls and Biodac composite formulation. 

Weight Indeed, the modified board was 14% lighter compared with the conventional board  

However, mechanical properties of the modified board were practically the same or even lower. 

Flexural Strength (ultimate load, 14-in. span, center-point load)
