Tensile tests of phenol formaldehyde glass‐powder‐reinforced composites: Pilot study

Abstract

Phenol formaldehyde was filled with glass powder (GP) to optimize the strength and impact toughness of the composite for structural applications by a research center at the University of Southern Queensland. To reduce costs, the center wished to fill as much of the glass microspheres as possible to maintain sufficient strength and impact toughness in the composites in structural applications. In this project, we varied the weight percentages of the GP in the composites, which were then subjected to tensile tests. The best weight percentage of GP that could be added to the phenolic resin to give the optimum yield, tensile strengths, Young's modulus, and cost was found to be about 10%. The contribution of this study was the finding that if the tensile properties are the most important factors to be considered in the applications of the composites, GP is not a suitable filler.

Flexural Properties of Epoxy Composites Filled with Glass Powder: Preliminary Results

“…The rise was 32.2 %. The drop in stiffness was in line with that obtained by dynamic thermal analysis [8]. The flexural modulus of aminimide-cured mica flakes reinforced epoxy resin composites increased exponentially with increasing volume fraction of the reinforcer, provided only up to 0.15 volume fraction of mica flakes were added [13].…”

Digital Light Processing of Highly Filled Polymer Composites with Interface-Mediated Mechanical Properties

“…In general, glass and DTES-functionalized glass composites exhibit more interfacial debonding than composites with MAPTES- and APTES-functionalized glass microspheres. This indicates poor compatibility between the polymer matrix and glass or DTES-functionalized glass microspheres, ,, which leads to the overall inferior mechanical performance presented in Figure and Table . Meanwhile, no obvious defects can be found for printed samples with MAPTES- and APTES-functionalized microspheres, as shown in Figures b and d, respectively.…”

Оптимізація Вмісту Добавок У Складах Композиційних Матеріалів Методами Експериментально-Статистичного Моделювання

“…До таких матеріалів можна віднести рідкі композиційні системи, наповнені скляними та алюмосилікатними мікросферами на основі полімерів [6][7][8]. Відношення до теплоізоляційних характеристик таких матеріалів не є однозначним [9][10]. Тому актуальною залишається задача з розробки і вивчення їх властивостей та дослідження з ефективного використання подібних композиційних матеріалів.…”
