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...

Wind-driven rain (WDR) is one of the largest moisture sources affecting hygrothermal performance and durability building envelopes. Accurate estimation WDR loads on facades as boundary condition important for analysis In this work, computational fluid dynamics (CFD) simulations semi-empirical models are used to compare load in urban environment open field. The research focuses two historical bu...

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...
