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.

Interface strength in glass fibre-polypropylene measured using the fibre pull-out and microdebond methods [PDF]

open access: yes, 2009
Interface strength in glass fibre-polypropylene was measured using both fibre pull-out and microdebond methods. Excellent compatibility between two methods was obtained. The data from microdebond test could be divided into two groups according to whether

The influence of oxidative-thermal degradation of polypropylene on measured interface strength of glass fibre-polypropylene [PDF]

open access: yes, 2010
It was previously found that thermal-oxidative degradation of the polypropylene could significantly affect the measured interfacial strength of glass fibre reinforced polypropylene (GF-PP) micro-composite.

Injection moulded all-polypropylene composites composed of polypropylene fibre and polypropylene based thermoplastic elastomer [PDF]

open access: yes, 2012
All-polypropylene composites comprising of polypropylene based thermoplastic elastomer (TPE) matrix and homo-polypropylene (hPP) fibre reinforcement were prepared and processed by injection moulding.

Development and characterisation of injection moulded, all-polypropylene composites [PDF]

open access: yes, 2012
In this work, all-polypropylene composites (all-PP composites) were manufactured by injection moulding. Prior to injection moulding, pre-impregnated pellets were prepared by a three-step process (filament winding, compression moulding and pelletizing).

Characteristics of the fibroplasia and collagen expression in the abdominal wall after implant of the polypropylene mesh and polypropylene/polyglecaprone mesh in rats [PDF]

open access: yesActa Cirúrgica Brasileira, 2016
PURPOSE: To compare fibroplasia and the resistance of the abdominal wall when polypropylene meshes and polypropylene/poliglecaprone are used. METHODS: Seventy-seven male Wistar rats were divided into three groups: Control Group (for resistance); Group E

Modification of polypropylene mesh by titanium compound: An in Vivo and in Vitro study

open access: yesFrontiers in Materials, 2023
Objective: Previous basic studies on the use of titanized polypropylene meshes in abdominal external hernia repair are not only limited, but also highly controversial.

Polypropylene/hemp woody core fiber composites: Morphology, mechanical, thermal properties, and water absorption behaviors

open access: yesAdvances in Mechanical Engineering, 2016
Natural fiber composites composed of polypropylene, maleic anhydride-graft-polypropylene, and hemp woody core fiber were produced by two-roll mill mixing. The hemp woody core fiber was treated by alkaline.

Temperature dependence of the interfacial shear strength in glass reinforced polypropylene and epoxy composites [PDF]

open access: yes, 2013
We have recently reported the development of a method which allows the measurement of IFSS over a wide temperature range [6,7]. In this paper we present data obtained using the microbond test in the temperature controlled environment of a thermo ...
