Hygrothermal and compressive mechanical behavior of composites plate with open-hole

Cailiao gongcheng
The mechanical properties of polymer matrix composites often decrease due to hygrothermal environment. The hygrothermal aging tests and the compression tests are carried out before and after aging on the T700/BP9916 composites plate with open-hole， and ...

Tuning Acetal and Disulfide Network Dynamics in Dynamic Diamine‐Cured Partially Bio‐Epoxy Networks

Journal of Applied Polymer Science, EarlyView.
This study investigates the development of high‐performance, sustainable vitrimers by balancing partially bio‐based epoxy resins with dynamic hardener chemistry. The research identifies how resin architecture and specific curing agents influence thermal stability, bond‐exchange kinetics, and environmental durability.

Whole‐House Thermal Bridge Modelling for Accurate Retrofit Energy Prediction

Energy Science &Engineering, EarlyView.
This study models thermal bridging in a UK semi‐detached house across pre‐ and post‐retrofit scenarios using piecemeal and whole‐house approaches with EWI and IWI. Whole‐house retrofits reduce heat transfer coefficient by 60%; findings demonstrate that default values are often unrepresentative and advocate tailored Ψ value databases.
