Overview of Existing Models

Modeling of temperature-dependent mechanical properties for FRP materials was started in the 1980s. In many of the suggested models [1-5], -modulus were described as stepped functions of temperature achieved by coimecting experimentally gathered key points, such as the glass-transition temperature, Tg, and the decomposition temperature, T. -modulus values at different temperatures were obtained by DMA. 

An empirical temperature-dependent -modulus function was proposed by Springer in 1984 [6] and is described by Eq. 5.1  

Gibson et al. [8] presented a temperature-dependent E-modulus model in 2004. Mechanical properties were assumed to degrade during the glass transition as described by Eq. 5.3  

A theoretical model for a temperature-dependent E-modulus was developed by Mahieux and Reifsnider [9,10]. In this model, WeibuU-type functions were used to describe the modulus change, over the full range of transition temperatures. 

An empirical model temperature-dependent E-modulus was proposed by Gu and Asaro in 2005 [11]
