Adhesive Distribution between Paper Components of Cigarettes

Abstract

The objective of this contribution is to characterise the distribution of adhesive between the plug wrap paper and the tipping paper on a finished cigarette. On the one hand, it is well known that this distribution influences various properties of the cigarette, but on the other hand, there are no methods available to completely determine this distribution. The area covered by adhesive, the amount of adhesive, and the thickness and position of the adhesive layer between the plug wrap and the tipping paper were chosen as essential quantities. Image analysis was used to evaluate the area covered by adhesive, and the amount of adhesive between the papers. The thickness and position of the adhesive layer were determined by processing pictures of paper cross-sections obtained with a time-of-flight secondary ion mass spectrometer (TOF-SIMS).

Influence of Honeycomb Core Stabilization on Composite Sandwich Structure Geometry

Abstract

Authors showed the influence of stabilization of the honeycomb core on shape of the composite sandwich test panel. Adhesive film laid on core ramps and cured with suitable cure cycle served as core stabilizer. Test panel geometry included different ramp angles (20° and 30°). To verify stabilization process a technology trial was performed. Three test panels were manufactured (3-stage, 1-stage and 1-stage with stabilized core). All test panels were manufactured in OoA process (Out of Autoclave). Panel surfaces were scanned with 3D scanner and compared with the reference CAD model. Both outer skin and inner skin were manufactured in Automated Fiber Placement Laboratory of Warsaw Institute of Aviation.

Biocomposites based on collagen and keratin with properties for agriculture and industrie applications

Introduction For the most part, scientific studies dedicated to biocomposites based on collagen and keratin have been oriented towards the medical field, especially for regeneration, vascular and cardiac reconstruction, cosmetic treatments ( 1 ). Studies on collagen mixtures with synthetic polymers have been aimed both at making materials for medical use ( 2 , 3 ) and for industrial applications such as biodegradable films, finishing binders, adhesives for the wood industry ( 4 ). For example, studies on collagen and keratin extracts used in the formulation

Correlation of rheoencephalography and laser Doppler flow: a rat study

by the Walter Reed Army Institute of Research (DataLyser). Data were acquired at a 200 Hz sampling rate. The head of each rat was secured by a gas anesthesia head holder (designed for rats) of the stereotaxic frame (David Kopf Instruments, Tujunga, CA). The skin was removed to expose the cranium between the sutura frontalis and the sutura lambda. The exposed bone was rinsed with hydrogen peroxide in preparation for the application of acrylic adhesive. Four burr holes (0.8 mm) were drilled for insertion of intracranial electrodes (E 363 / 1, Plastics One, Roanoke
