Single Polymer Composites Based on Polypropylene: Processing and Properties [PDF]

open access: yes, 2004
PhDIsotropic polymers lack sufficient strength and stiffness for many engineering applications. In order to improve these properties polymers can be filled with structural reinforcements such as glass or natural fibres.

The role of residual thermal stress in interfacial strength of polymer composites by a novel single fibre technique [PDF]

open access: yes, 2012
The temperature dependence of the interfacial properties of glass fibre reinforced polypropylene and epoxy composites was investigated using a novel microbond test in the temperature controlled environment of a thermo-mechanical analyser.

Prediction of the Thermal Conductivity of Polypropylenes and Propylene Copolymers Based on Crystallinity or Elastic Modulus

open access: yesJournal of Applied Polymer Science, EarlyView.
The thermal conductivity of isotactic and low‐tacticity polypropylenes as well as random, heterophasic, and random heterophasic propylene‐based copolymers, measured with the transient plane source method, is found to scale linearly with crystallinity and logarithmically with Young's modulus.

Behaviour of alkaline cement mortars reinforced with acrylic and polypropylene fibres

open access: yesMateriales de Construccion, 2000
In the present work, the behaviour of alkaline cement mortars reinforced with fibres of different nature (acrylic and polypropylene fibres) is studied. Also the chemical stability of those fibres in strong alkaline medium has been investigated.

Barrier Properties and Crystalline Structure of Biowax‐Containing Water‐Based Polymer Dispersions Under Different Processing Conditions

open access: yesJournal of Applied Polymer Science, EarlyView.
This study investigates the nanoscale structures of biowax materials using the wide‐angle x‐ray scattering method. The biowaxes are combined with water‐based polymer dispersions to create barrier coatings for fiber‐based food packaging materials.

Effects of oropharyngeal neuromuscular stimulation on the volumetric enlarged and reduced tongue base in minipigs

open access: yesThe Anatomical Record, EarlyView.
Abstract Hypoglossal nerve or tongue protruding muscle stimulation is a current treatment option for obstructive sleep apnea. Thus, the present study analyzed 3D deformations of the volumetric enlarged and reduced tongue base upon oropharyngeal neuromuscular stimulation.

Fabrication process optimization of hemp fibre-reinforced polypropylene composites

open access: yes, 2013
Natural fibre-reinforced composites have attracted great research and economic interests because of their outstanding 'green' characteristics compared with glass fibre-reinforced composites. It is very important to understand the processing effect on the

Arthroscopic Suture‐Only Intra‐articular Soft‐Tissue Long‐Head Biceps Tenodesis to the Rotator Cuff

open access: yesArthroscopy Techniques, EarlyView.
Abstract Pathology of the long head of the biceps tendon (LHBT) is a prevalent source of shoulder pain and is often concomitant with rotator cuff diseases. Various treatment modalities exist for addressing this condition, including surgical approaches, anatomical sites for tenodesis fixation, and types of fixation devices employed.
