FRP-to-Softwood Joints: Experimental Investigation [PDF]
, 2011 A proper understanding of the interfacial behaviour between timber and bonded fibre-reinforced polymer (FRP) composites will assist in the rational and optimal design of FRP strengthening works for timber structures. To enhance this understanding, a series of single-lap FRP-to-timber joint shear tests are reported herein in which the strength of the ...

Char Layer Thickness Evolution During Structural Timber Fire Experiment and Final Density Profile
Fire and Materials, EarlyView.ABSTRACT This paper evaluates several non‐destructive experimental methods for determining the char layer thickness and its density profile in structural timber samples exposed to standard ISO 834 fire curve experiments. Microwave echo pulse, ultrasonic echo pulse, X‐ray computed tomography, and resistance drilling were evaluated.

Low‐Hysteresis Cellulose‐Based Hydrogels for Strain Detecting
Macromolecular Rapid Communications, EarlyView.Low‐hysteresis hydrogel with high cellulose content is prepared. The modified cellulose is prepared through a sequential periodate oxidation and borohydride reduction process. The hydrogel can be used as a strain sensor with a gauge factor of 1.1 in the 0%–300% sensing range.
