Seismic strengthening of beam-column joints with multidirectional CFRP laminates [PDF]
, 2012 An experimental program was carried out to analyse the potentialities of a technique based on the use of multidirectional CFRP laminates (MDL-CFRP) for the seismic repair and strengthening of reinforced concrete (RC) beam-column joints. This experimental

Emissivity measurements of reflective surfaces at near-millimeter wavelengths [PDF]
, 1995 We have developed an instrument for directly measuring the emissivity of reflective surfaces at near-millimeter wavelengths. The thermal emission of a test sample is compared with that of a reference surface, allowing the emissivity of the sample to be ...

FINITE ELEMENT ANALYSIS OF CFRP REINFORCED CONCRETE SLABS INCLUDING CFRP ANCHORS
, 2023 The flexural reinforcement of slabs with CFRP is a well-established retrofit technique; however, delamination continues to be the primary factor constraining the strength enhancement. Prior studies have demonstrated that CFRP anchors can effectively postpone delamination, yet the complete understanding of the influence of various design variables on ...

Impact and Post‐Impact Properties of Carbon Fiber Fabric Laminates Reinforced With Carbon Nanofibres
Polymer Composites, EarlyView.Carbon nanofiber addition on the low‐velocity impact response of carbon fiber laminates. ABSTRACT The use of carbon fiber reinforced polymers (CFRPs) is limited by their susceptibility to low‐velocity impact (LVI) damage. This study investigates the effect of incorporating 0.75 wt.% carbon nanofibres (CNFs) into the epoxy matrix of carbon fiber fabric ...

Modeling Fiber Dispersion in a Single‐Screw Extruder for Long Fiber‐Reinforced Thermoplastics
Polymer Composites, EarlyView.Fiber dispersion throughout the screw channel ABSTRACT Understanding the mechanics of fiber attrition during the plasticizing process is important in predicting the strength of long fiber‐reinforced thermoplastics (LFT) composites. Fiber dispersion has been found to impact fiber damage during processing and therefore final fiber length in the final ...
