To obtain a tensile strain-hardening behavior by using the ordinary polypropylene (PP) fiber, micromechanical model recommends increase of fiber low interfacial bond with an cementitious matrix. It was predicted that alkali-activated slag (AAS) composite high drying shrinkage performance would affect interface frictional during pullout.

Oriented short hemp fibre mats were produced using dynamic sheet forming (DSF) incorporating cellulose nanocrystals (CNCs) to improve their integrity. The CNCs found act as a binder and mechanical strength of the well polypropylene matrix composites with mats. Improved thermal stability was also obtained for by CNC treatment

BACKGROUND Polypropylene mesh used as a mid-urethral sling is associated with severe clinical complications in a significant minority of patients. Current in vitro mechanical testing shows that polypropylene responds inadequately to mechanical distension and is also poor at supporting cell proliferation. AIMS AND OBJECTIVES Our objective therefore is to produce materials with more appropriate...

atechnical feasibility study has been conducted on production of nano- and micro-fibrils from nylon 6/polypropylene grafted with maleic anhydride/polypropylene blended films. fibrils are prepared in four consecutive steps.in the first step the polymers melt blended in an extruder with and without compatibilizers to produce chips; in the second step films are extruded from polymer blends chips, ...
