The Experimental Research on the Scaling Effects on the Strength of Fibre Reinforced Plastic Materials Zhang Li; Yang Yong; Zhang Heng; Wen Dijiang (Assoc. Prof., Institute of Materials Science and Engineering, WUT, Wuhan 430070, China.) This research finds out the role of the strength varying with the thickness by measuring the bending strength of glass fibre reinforced plastic plates of different thickness. This paper lays a foundation for structural design and calculation. composites; scaling effects; scaling
