Effect of fibre treatments on interfacial shear strength of hemp fibre reinforced polylactide and unsaturated polyester composites [PDF]

open access: yes, 2011
Surface treatment of hemp fibres was investigated as a means of improving interfacial shear strength (IFSS) of hemp fibre reinforced polylactide (PLA) and unsaturated polyester (UPE) composites. Fibres were treated with sodium hydroxide, acetic anhydride,

Estimation on Economic Cost of China's New De-sulfur Policy During Her Gradual Accession to WTO: The Case of Industrial SO2 Emission [PDF]

open access: yes
To understand the potential impacts of China’s accession to WTO in her new de-sulphur policy (reduction of 10% of SO2 emission in 2005 with respect to that of 2000), we construct a CGE model in which the SO2 emission is linked directly to energy ...

Vegetable Fibers for Composite Materials In Constructive Sector

open access: yesIOP Conference Series: Materials Science and Engineering, 2017
The aim of the research is to study and to test bio-mixture for laminas to use in construction field components. Composite materials are becoming more common in different sectors, but their embodied energy is an environmental problem. For this, in recent years, the researchers investigate new mixtures for composites, in particular with vegetable fibers
