Investigation of the strength of thermally conditioned basalt and e-glass fibres

摘要: It is projected that the total global production of composite materials will significantly exceed 10 million tons by 2015 which over 90% contain glass fibre reinforcement. Traditionally most this material would be directed to landfill at end life. Thus, recycling composites has started gain great importance due environmental and commercial aspects. The development an efficient process enable cost-effective regeneration mechanical properties for recycling, could result in a huge decrease disposal as well attenuation CO2 emissions. There are several processes available but technologically advanced thermal recycling. However, during fibres treated temperatures range between 300 up 600 °C exhibit drop strength sometimes considered not reusable or unsuitable reprocessing [1]. Although basalt been some time, recent processing resulted availability continuous similar form traditional fibre. often stated better high temperature resistance compared E-glass [2,3]. If were true then may show prospects survive end-of-life useful present work investigates compares changes E-Glass when heat-treated – °C. Since surface plays important role retained brittle fibres, investigation used with epoxy compatible sizings order maximise quality comparison. Results single testing tensile modulus presented discussed.
