The effects of acetylation on properties of flax fibre and its polypropylene composites
eXPRESS Polymer Letters, 2008 Flax fibre was modified with acetylation. The influence of the acetylation on the structure and properties of flax fibre were investigated as well as modified flax fibre reinforced polypropylene composites were also prepared.

Study on the flexural properties of metallic-hybrid-fibre-reinforced concrete [PDF]
Maejo International Journal of Science and Technology, 2010 This contribution investigates the flexural properties of metallic-hybrid-fibre-reinforced concrete. Two types of fibres were used: amorphous metallic straight fibre characterised as non-slipping fibre due to its rough surface and large specific surface ...

Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Tensile properties of alkalised jute fibres
BioResources, 2009 The structure of jute fibre has been modified using caustic soda up to a limit in order to improve its performance. The SEM micrographs of untreated jute fibres show a smooth surface, while alkalised jute fibres show rough and void regions between individual fibre cells.

Some intersection properties of the fibres of Springer’s resolution [PDF]
Proceedings of the American Mathematical Society, 1984 Let X be the fixed point set in the flag variety of a unipotent element u in \(GL_ n\). The irreducible components of X are in bijective correspondence with standard Young tableaux. The intersection properties of these components have connections with the theory of Kazhdan-Lusztig polynomials.

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

Polymer Testing, 1996 The polarizing interference microscope is used with a fibre manipulation device to study, dynamically, the variation of refractive indices and birefringence of PE fibres with the draw ratio. The resulting data were used to calculate Poisson's ratio over all strain ranges.

Advanced Engineering Materials, EarlyView.A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Advanced Engineering Materials, EarlyView.Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.
