Optically-derived mechanical properties of glass fiber-reinforced polymer laminates for multifunctional load-bearing structures:

摘要: This paper demonstrates how the translucency of glass fiber-reinforced polymer (GFRP) laminates allows derivation their mechanical properties through optical measurements. Spectrophotometric, goniophotometric and tensile experiments were performed on unidirectional cross-ply hand lay-up GFRP with fiber volume fractions ranging from 0.15 to 0.45. An analytical model predict directional fractionsand thus laminateshas been developed based total diffuse transmittance light scattering laminates. It is demonstrated that structurally optimized can meet requirements for skylights encapsulation photovoltaic cells into translucent
