Post crack flexural toughness in steel fabric and fibre reinforced concrete beams [PDF]
, 2008 The purpose of the paper is to provide independent research and evaluate manufacturers’ claims that structural polypropylene fibres provide satisfactory crack control reinforcement and compare the test results from macro synthetic polypropylene fibres ...

Manufacturing Of Robust Natural Fiber Preforms Utilizing Bacterial Cellulose as Binder [PDF]
, 2014 We present a novel method of manufacturing rigid and robust short natural fiber preforms using a papermaking process. Bacterial cellulose acts simultaneously as the binder for the loose fibers and provides rigidity to the fiber preforms.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective To determine the concentration of glial fibrillary acidic protein (GFAP) in cerebrospinal fluid (CSF) and plasma in Alexander disease (AxD) and whether GFAP levels are predictive of disease phenotypes. Methods CSF and plasma were collected (longitudinally when available) from AxD participants and non‐AxD controls.

Tensile creep behaviour of polypropylene fibre reinforced polypropylene composites
Polymer Testing, 2005 Creep, the deformation over time of a material under stress, is one characteristic of composites that has resulted in poor performance in certain applications. This work was undertaken to investigate the advantages of using PP fibres in random poly(propylene-co-ethylene) (PPE) with different fibre concentrations.

Tensile properties of polypropylene fibres [PDF]
, 2009 As soon as it appeared on the market, half a century ago, polypropylene appeared as a promising fiber-forming polymer but with some difficulties in processing due to a lack of control of its viscoelastic properties and in durability due to its low stability to oxidation.

High temperature behaviour of polypropylene fibres reinforced mortars
, 2015 International audienceThe aim of this paper is primarily experimental and is intended to analyse the behaviour of two cementitious materials, before and after heat treatment: one unreinforced (i.e.

Advanced Engineering Materials, EarlyView.The study investigates novel semi‐finished products made of unidirectionally arranged hemp or pineapple leaf fiber‐reinforced composites produced from different matrices. The materials are analyzed in terms of their mechanical and interfacial properties and void content.

Modelling and Simulation in Engineering, 2016 A tensile test until breakage and a creep and relaxation test on a polypropylene fibre are carried out and the resulting creep and stress relaxation curves are fit by a model adopting a fraction-exponential kernel in the viscoelastic operator. The models

Rheological, Colour and Processing Properties of Polypropylene Masterbatches for Nanocomposite Fibre Preparation [PDF]
Tekstilec, 2017 Asia’s current dominance of the global production of standard types of chemical fibres requires the sophistication of European fibre and textile products. Modifying the mass or surface of materials using nanotechnologies is one of the most promising ways
