To completely segment all individual wood fibres in volume images of fibrous materials presents a challenging problem but is important in understanding the micro mechanical properties of composite materials. This paper presents a filter that identifies and closes pores in wood fibre walls, simplifying the shape of the fibres. After this filter, a novel segmentation method based on graph cuts id...

One of the main issues with Carbon Fiber Reinforced Thermoplastics (CFRTP) is poor impregnation quality matrix on carbon fiber due to high viscosity thermoplastic. Impregnation can significantly affect mechanical properties composite. This study aims compare abilities various types thermoplastic matrices fiber. The used in this are HDPE, PC, and PET. Three variations treatment were employed: fi...

I describe possible ways to discover hard double pomeron exchange (HDPE) with the existing detectors at the Fermilab Tevatron, by using the small-angle " luminosity " counters as a veto. Estimates of the cross sections and backgrounds are made. In addition to the intrinsic importance of HDPE, its observation would be useful for calibrating the detectors, and for estimating the " survival probab...

Osteolysis remains the most important problem in orthopedic implant failure. Wear debris from the implant contains polyethylene (PE) particulate which has been shown to activate monocyte-derived macrophages (MDM). Although the response of MDM has been shown to be influenced by the size, shape, and chemical type of PE, the effect of chemically altered PE on MDM has not been studied. In this stud...

In this work, the potential for usage recycled polystyrene and wood flour wastes as materials for development wood plastic composites was evaluated. The effects of wood flour loading and coupling agent addition on the mechanical, dynamic mechanical and morphological properties of polystyrene wood flour composites were examined. The results showed that the mechanical properties decreased with th...

Strand-based composites are formed by arranging wood strands in a mat and bonding them together with adhesives under heat and pressure. The performance of these products is governed by the properties of wood strands, adhesive, manufacturing strategy, and production process. In this paper, a method of building a model to represent internal structure of oriented strandboard (OSB) based on x-ray t...

Introduction In wood industry, adhesive bonding is one of the key process steps. To ensure continuing technological progress in wood industry it is necessary to explore new possibilities of improvement in adhesive bonding. The potential routes for performance improvements suggested by a state of the art report issued by COST Action E13 Wood Adhesion and Glued Products (Dunky et al. 2002) focus ...

In this study, HDPE-based flat-pressed WPCs were reinforced with glass fibre and carbon woven fabrics, which could be used where high strength stiffness are required. The effect of reinforcement on some physical, mechanical, thermal properties fire performance was investigated. According to the results, increase in fabric density resulted holding much water microvoids fabric, increased absorpti...
