The hygroscopicity of moso bamboo (Phyllostachys edulis) with a gradient fiber structure

Description: This article studies the hygroscopicity of moso bamboo (Phyllostachys edulis) with a gradient fiber structure assessed by a dynamic vapor sorption (DVS) apparatus and fitted with a Haillwood–Horrobin (H–H) model. The effects of the chemical composition, gradient fiber structure, and mesopore structure of the bamboo were also investigated. The results demonstrate that the hygroscopicity of bamboo gradually increases from the outer to the inner layer along the thickness of the culm wall, which is… more

Effect of amorphous cellulose on the deformation behavior of cellulose composites: molecular dynamics simulation

Description: This article is a study aimed at predicting and enhancing the properties of the blend, as well as exploring the mechanism, of a polylactic acid (PLA)/amorphous cellulose composite system through molecular characterization. The static properties of the amorphous cellulose/PLA blend model and the mechanical response of the material under uniaxial tension were studied by molecular dynamics simulation to establish the structure–property relationship.

Fiberboard Made from Scrap Denim: Characterization of its Properties by Effective Bulk Modulus Elastography

Description: Article describes how fiberboards from scrap denim were fabricated using two different resins, melamine urea formaldehyde (MUF) and polymeric methylene diphenyl diisocyanate (pMDI). Resin content and MUF-pMDI weight ratio were studied. Physical and mechanical tests determined the modulus of elasticity (MOE), modulus of rupture (MOR), internal bond (IB), thickness swell (TS), and water absorption (WA).
