Effect of static mixer on fiber orientation of injection molded fiber‐reinforced composites
SPE Polymers, 2022 The effect of an in‐mold static mixer on orientation of fiber‐reinforced polypropylene (PP) was explored within the injection molding process. Several mold geometries and helical mixer designs were assessed via simulation to identify the mixing ability ...

Oriented manifolds fibered over the circle [PDF]
Proceedings of the American Mathematical Society, 1966 This note is concerned with the following problem: Which classes in the oriented cobordism ring ft* can be represented by a manifold fibered differentiably over the circle, and can one give a constructive method for obtaining such representatives? (For the unoriented case see [2]).

Advanced Engineering Materials, EarlyView.Carbon nanomaterial‐reinforced epoxy composites exhibit pronounced piezoresistive behavior, enabling intrinsic damage sensing under cyclic and fatigue loading. This review critically compares carbon nanotube and graphene systems, correlating filler content, percolation threshold, and gauge factor with sensing stability and damage evolution.

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated
