Structure-property relationships in glass reinforced polyamide, part 2: The effects of average fiber diameter and diameter distribution [PDF]
, 2006 We present the results of an extensive study of the influence of average fibre diameter and the width of the diameter distribution on the performance of injection moulded glass-fibre reinforced polyamide 66. In the average fibre diameter range from 9-18m

Ground Hemp Fibers as Filler/Reinforcement for Thermoplastic Biocomposites
Advances in Materials Science and Engineering, 2015 Mechanical properties (tensile, flexural, and impact) of ground hemp fibre polypropylene composites were investigated. Ground alkali-treated hemp fibre and noil hemp fibres with various initial fibre lengths were utilized to reinforce polypropylene ...

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

Stress birefringence in polypropylene fibres
Polymer Testing, 1987 Abstract Refractive indices and birefringence changes with strain produced by different stresses in undrawn polypropylene fibres have been measured dynamically by interferometry. A micro-strain device connected to a wedge interferometer has been constructed.
