This paper is concerned with fatigue of polypropylene/glass-®bre thermoplastic composites produced from a bidirectional woven cloth mixture of E glass ®bres and polypropylene ®bres. The latter becomes the matrix after the application of heat and pressure. This composite was manufactured with a ®bre volume fraction Vf of 0.338. The e€ect of layer design on the static and fatigue performance was ...

The present work aims at investigating the thermal properties of a wide range of semicrystalline nanocomposites based on poly(amide)-6 (PA6), ethylene-vinyl acetate copolymer (EVA), poly(ε-caprolactone) (PCL) or polypropylene (iPP), in combination with various types of nanofillers (layered silicates, carbon nanotubes, sepiolite, or POSS). We report on the effect of nanofillers on the quasi-isot...

INTRODUCTION Adhesions to mesh/tacks in laparoscopic ventral hernia repair are often cited as reasons not to adopt its evidence-based superiority over conventional open methods. This pilot study assessed the occurrence of adhesions to full-sized Polypropylene and Gore-tex DualMesh Plus meshes and the possibility for adhesion prevention using fibrin sealant. METHODS Two 10-cm to 15-cm pieces ...

This work presents an improved single fiber pull-out test for fiber/matrix interface characterization. This test has been used to study the Inter-Facial Shear Strength ‘IFSS’ of hemp fibers reinforced polypropylene (PP). For this aim, the fiber diameter has been carefully measured using a tomography inspired method. The fiber section contour can then be approximated by a circle or a polygon. Th...

This study presents the preparation of polypropylene composites filled with mixtures of household waste of mate-tea and wood particles to increase the economic value chain of mate-tea, especially in Latin America. Filler mixtures in proportions ranging from 0 to 60% depending on the type of particle were used. The polypropylene matrix was fixed at 40% and roughness surface and color evaluation ...

Polypropylene Fiber Reinforced Concrete is an embryonic construction material which can be described as a concrete having high mechanical strength, Stiffness and durability. By utilization of Polypropylene fibers in concrete not only optimum utilization of materials is achieved but also the cost reduction is achieved. This paper presents a comprehensive review on various aspects Polypropylene F...
