Abstract Interest in sustainable building materials is recently growing up due to the environmental pollution and consequent need reduce energy consumption. The sector alone responsible of major share total expenditure mainly indoor heating cooling. This huge amount can be reduced by choosing efficient thermal insulators based on renewable natural sources. Among bio-based components by-products...

The aim of this study is the numerical investigation of the capacity of porous hygroscopic building materials to damp indoor humidity variations due to external environmental loads and internal sources due to heat and moisture exchange. By means of numerical simulation, building material moisture content is computed by using a basic approach based on a diffusion model. Subsequently, a model inc...

In this study, electrodes on a exible printed circuit board (FPCB) and rigid printed circuit board (RPCB) were bonded together by thermo-compression (TC) bonding, using a Sn-3.0Ag-0.5Cu solder as an interlayer. In order to investigate the hygrothermal reliability of the TC bonded FPCB/RPCB joints, a temperature-humidity (TH) test of 85°C/85% relative humidity, and a 90° peel test, were conducte...

Commercial energy consumption currently accounts for 8.6% of the total national in India and it is predicted to surge upcoming years. To tackle this issue, building envelope insulation being promoted through codes standards reduce cooling heating demand hence overall demand. However, with prolonged exposure humid ambient conditions warm-humid locations, materials undergo decay their hygrotherma...

Hygrothermal aging of neat poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and PHBV filled with an organomodified montmorillonite (C30B) at 3wt. was investigated 65°C 100% relative humidity (RH) up to 100 days. FT-IR data indicated that the carbonyl intensity index decreased exposure time for both samples, while main degradation mechanism occurred through hydrolysis reaction. This led chain...
