Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Single fibre pull out was used to investigate the interfacial shear strength (IFSS) between Polyethylene Terephthalate (PET) fibre and Polypropylene (PP) matrix containing various percentages of maleic anhydride (MA). Glass Fibre (GF) – PP was used as a benchmark for the PET-PP IFSS to ascertain whether PET fibre could match the IFSS performance of glass fibre. The results of the pull out test show that the IFSS of PET – PP increase from 1.3MPa to 5.5MPa when increasing the MA content from 0% to 10% with maximum GF – PP IFSS reaching 10.2 MPa at 1.5% MA.
