Mechanical and physical properties of agro-based fiberboard

Informally Refereed

Abstract

In order to better utilize agricultural fibers as an alternative resource for composite panels, several variables were investigated to improve mechanical and physical properties of agm-based fiberboard. This study focused on the effect of fiber morphology, slenderness ratios (UD), and fiber mixing combinations on panel properties. The panel construction types were also investigated such as hardboard (HB), medium density fiberboard (MDF), and bagasse core panel (BCP) made from bagasse/bamboo combinations with a combination of 1% pMDI/4% UF as a binder. Static bending properties and tensile strength increased as fiber UD increased from 3 to 26. Fiber separation and morphology also influenced the mechanical property development of agm-based panels. Bagasse fiber bundles and particles smaller than UD of 5.4 were responsible for the mechanical property loss of apbascd MDF. The BCP yielded promising results for modulus of elasticity (MOE) and modulus of rupture (MOR). However, HB appeared to be a better panel type for agro-based composites based on the property enhancement compared to wood-based panel products.
