Tailored TMES‐Modified Polyimide–Silica Aerogels for Enhanced Mechanical Performance and High‐Temperature Aerospace Applications

Natural Sciences, Volume 6, Issue 2, April 2026.
ABSTRACT The development of high‐performance thermal insulation and lightweight materials in aerospace applications requires overcoming the limitations of conventional aerogels. While polyimide (PI) aerogel offers flexibility and thermal stability, it suffers from shrinkage and a hydrophilic nature.

Dual‐Function In Situ Ti3(Cu,Al)3O Reinforcement for Simultaneous Strengthening and CTE Reduction in Sapphire/TC4 Active‐Brazed Joints

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT The thermal expansion mismatch between sapphire and Ti‐6Al‐4V (TC4) alloy has traditionally limited the shear strength of ceramic‐metal joints to ≤ 170 MPa. In this study, active brazing with Ag‐35.25Cu‐1.75Ti (wt%) leads to the formation of a dual‐function microstructure, wherein uniformly dispersed submicron Ti3(Cu,Al)3O particles embedded ...

Influence of the Wire Feeding on the Wetting Process during Laser Brazing of Aluminum Alloys with Aluminum-Based Braze Material

Journal of Manufacturing and Materials Processing, 2019
The wetting behavior in laser brazing can be designated as inconstant, caused largely by external process discontinuities such as the wire feeding. To reveal periodic melt pool propagation effects that occur during laser brazing of aluminum and for a ...
