Damage resistance of composites based on glass fibre reinforced low styrene emission resins for marine applications ArchiMer
Perrot, Yves; Baley, C; Grohens, Y; Davies, Peter.
Composites based on glass fiber reinforced low styrene emission polyester resins have been widely used over the last 10 years, in order to meet increasingly strict safety regulations, particularly in the pleasure boat industry. Previous studies of their mechanical properties suggested that although these resins are generally more brittle than traditional orthophthalic polyester resins this did not adversely affect the properties commonly used for quality control (short beam shear and tensile failure strength of mat reinforced composites). In the present paper results from a more detailed study of damage behaviour are presented. Tests include fracture toughness (K (Ic) ) tests on resins, fibre/matrix interface energy, detection of composite damage...

Mechanical properties of composites based on low styrene emission polyester resins for marine applications ArchiMer
Baley, Christophe; Perrot, Yves; Davies, Peter; Bourmaud, Alain; Grohens, Yves.
Glass fibre reinforced polyester composites are used extensively for hulls and decks of pleasure boats. Boat-builders must optimise manufacturing technology, not only with respect to mechanical properties but also limiting volatile organic compounds (VOC) emissions. One way to achieve this is through modified polyester resin formulations such as low styrene content, low styrene emission or combinations of these. The resin matrix selection procedure is based on design specification (mechanical behaviour) but also manufacturing requirements and cost considerations. For this application post-cure is rarely used so it is important to optimise curing conditions. In this study the influence of the curing cycle on mechanical properties was examined first for two...
