Incorporation of Lignin in Bio-Based Resins for Potential Application in Fiber-Polymer Composites

Mário Alexandre De Jesus Garrido, Mateus De Assunção Hofmann

Bio-based resins, obtained from renewable raw materials, are a more sustainable alternative to oil-based resins for fiber-reinforced polymer (FRP) composites. The incorporation of lignin in those resins has the potential to enhance their performance. This ...

Mechanical Properties of FRP Materials at Elevated Temperature. Definition of a Temperature Conversion Factor for Design in Service Conditions

Thomas Keller, Mário Alexandre De Jesus Garrido

One of the main concerns about the use of fibre reinforced polymer (FRP) materials in civil engineering structural applications is the potential reduction of their stiffness- and strength-related properties when exposed to elevated temperature. The first p ...
