A new thickness-based accelerated aging test methodology for resin materials: Theory and preliminary experimental study

Abstract

h i g h l i g h t s Thickness-based accelerated aging test method (ThAM) is firstly proposed for resin materials. Acceleration factors are theoretically deduced for water absorption and tensile behaviours of resin materials. Effects of specimen thickness on water absorption and tensile strength retention of resin materials are studied. The proposed ThAM ensures stable accelerated efficiency without changing the degradation mechanism of resin materials.

Multiscale mechanics and molecular dynamics simulations of the durability of fiber-reinforced polymer composites

“…It is worth noting these were a series of macro experiments. The Arrhenius equation k = k 0 exp(-E a /k B T), which gives the dependence of the rate constant k of a chemical reaction on a pre-exponential factor k 0 , the absolute temperature T, and the activation energy E a , is widely adopted to study the long-term durability of various materials 52,53 . To accelerate the testing process, a temperature-based accelerated method was proposed as follows:…”

Compressive Behavior of Circular Sawdust-Reinforced Ice-Filled Flax FRP Tubular Short Columns

“…More recently, fiber-reinforced polymer (FRP) composites have been increasingly used in civil engineering because of their high strength-to-weight ratios, good design flexibility, and excellent corrosion resistance even under harsh environment [10][11][12][13][14][15][16][17][18][19][20][21][22]. In the 1990s, Mirmiran and Shahawy [23] proposed concrete-filled FRP tubular (CFFT) columns.…”
