Dynamic hygrothermal behavior and energy performance analysis of a novel multilayer building envelope based on PCM and hemp concrete

Construction and Building Materials, 2022
13 Phase change materials (PCMs) have high thermal inertia while hygroscopic materials have high 14 hygric inertia. However, few studies have integrated the two materials and considered both 15 hygrothermal behavior and energy performance.

Hygrothermal behavior of polybenzimidazole

Polymer, 2016
Abstract Poly[2,2’-(m-phenylene)-5,5’-bibenzimidazole] (PBI) is used in extremely high temperature harsh environment applications. It is a unique engineering material that is formed into parts by powder-sintering at temperatures as high as 500 °C. Recently, ever increasing demands for high temperature polymers have led to significant interest in PBI ...

Degradation of Mechanical Properties of Flax/PLA Composites in Hygrothermal Aging Conditions

Polymers
The main advantage of green composites is their biodegradability, but this biodegradability can also be considered a drawback if the degradation appears during the service life of the component.

Effect of graphene nano-platelets coating on carbon fibers on the hygrothermal ageing driven degradation of carbon-fiber epoxy laminates

Composites Part B: Engineering
While spray coating of graphene nano-platelets (GNPs) on-to long carbon fibers (CF) is a viable strategy to enhance the strength of carbon fiber reinforced plastics (CFRP), the degradation of these laminates under hot and humid conditions remains ...
