This paper describes an experimental campaign specifically intended for the mechanical characterization of fillers. Fillers are two-components particulate composites, characterized by type, size and content of glass microsphere, randomly embedded in an epoxy matrix. Hull and superstructure of yachts are covered by filler to mould the surfaces. To obtain painted shiny surfaces, the filler should be perfectly levelled, faired and smoothed. Differently to the works presented in open literature, this paper focuses on the macro-mechanics properties regardless the fillers’ internal mechanic. Two types of tests were designed and conducted on six different fillers: a compression strength test on simple filler specimens and a three point bending test on specimens made by filler applied onto a steel substrate. Load-displacement curves of tested fillers were acquired providing the basis for the characterization of strength and stiffness. Results are repeatable and consistent and comparisons among different fillers are presented.

Abstract

This paper describes an experimental campaign specifically intended for the mechanical characterization of fillers. Fillers are two-components particulate composites, characterized by type, size and content of glass microsphere, randomly embedded in an epoxy matrix. Hull and superstructure of yachts are covered by filler to mould the surfaces. To obtain painted shiny surfaces, the filler should be perfectly levelled, faired and smoothed. Differently to the works presented in open literature, this paper focuses on the macro-mechanics properties regardless the fillers’ internal mechanic. Two types of tests were designed and conducted on six different fillers: a compression strength test on simple filler specimens and a three point bending test on specimens made by filler applied onto a steel substrate. Load-displacement curves of tested fillers were acquired providing the basis for the characterization of strength and stiffness. Results are repeatable and consistent and comparisons among different fillers are presented.
