Study of Mechanical Properties of High Quality Phenolic Molding Compounds

Abstract:

Currently, there are many unresolved issues to produce high quality phenolic molding compounds (PMC), which are widely used in many industry sectors. In this paper, we design a new approach to resolve some issues, and produce high quality PMC from phenolic resins, fillers, curing agents, and modified fiberglass by silane coupling agents. The preparation processes and the mechanical properties of the newly prepared PMC are studied extensively, and typical composite properties are: volume resistivity of 2.4×10¹³Ω.cm, surface resistivity of 3.9×10¹³Ω.cm, impact strength of 2.65KJ/m², bending strength of 95.9MPa, electric strength of 12.28mv, heat deflection temperature of 240°C, fluidity of 0.26mm, electric strength of 12.28mv, specific gravity of 1.661g/mL. Compared with currently used approaches, our approach can produce PMC with better overall performance and lower costs. This paper has two contributions, one is to propose and test a new approach for producing high quality PMC, and another is that we made a high quality PMC material with low costs.
