Interfacial strength in thermoplastic composites - at last an industry friendly measurement method? [PDF]

open access: yes, 2001
Many elegant techniques have been developed for the quantification of composite micro-mechanical parameters in recent years. Unfortunately, most of these techniques have found little enthusiastic support in the industrial product development environment,

Characterization of Clinical Phenotype to Glial Fibrillary Acidic Protein Concentrations in Alexander Disease

open access: yesAnnals 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.

The effects of acetylation on properties of flax fibre and its polypropylene composites

open access: yeseXPRESS 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.

Fibre reinforced alkali activated composites exposed to elevated temperature

open access: yesEngineering and Applied Science Research, 2022
This work aims to reveal the effect of fibres on the strength and durability of alkali activated composites (AAC). AAC specimens were prepared by alkali activation of Ground granulated blast furnace slag (GGBS). Two types of fibres i.e. micro steel (~237.

Tensile creep behaviour of polypropylene fibre reinforced polypropylene composites

open access: yesPolymer 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]

open access: yes, 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.

Polypropylene fibres within concrete with regard to heat induced spalling and reduction in compressive strength [PDF]

open access: yes, 2008
The paper examines the effect of various polypropylene fibre additions (Types 1 and 2 and different fibre volumes) to concrete with regard to explosive spalling when subject to high temperatures similar to that experienced in building or tunnel fires ...

A comparison of the results from intra-pleural and intra-peritoneal studies with those from inhalation and intratracheal tests for the assessment of pulmonary responses to inhalable dusts and fibres. [PDF]

open access: yes, 2016
The aim of this paper is to compare results from inhalation studies with those from intraperitoneal and intrapleural tests, where available, for a number of fibrous and particulate test materials.

Unidirectional Tape‐Based Composites from Hemp and Pineapple Leaf Fiber: Mechanical Performance in Conventional and Bio‐Based Matrices

open access: yesAdvanced 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.
