چکیده
One of the areas wood waste processing is their use in production wood-polymer composites (WPC). The relevance products due to wide range applications and qualities this material. WPC does not rot, damaged by insects fungi, contain harmful binders. Products from duodenum do crack, gouge, are waterproof, which makes them an excellent material for manufacturing a terrace board. However, board must have certain mechanical qualities, will allow it be used fairly harsh conditions - under action humidity, UV radiation load. This study aimed determine main physical properties (density, strength at static bending, modulus elasticity, water absorption, hardness, abrasion resistance, changes linear dimensions with changing atmospheric environment) samples different fillers. Samples hollow board, were filled polyethylene (PE) polyvinyl chloride (PVC), study. Based on experimental studies, was found that density both quite high, close maximum; difference significant, but when examining microslices microscope PE as binder, larger number voids observed, indicating presence excess moisture or lack mineral It may also indicate destruction polymer. determined other important indicators such resistance best filler polyvinylchloride. greatest bending index 35%. hardness equivalent. elasticity sample exceeded performance PVC almost 2.5 times. Thus, based research, possible identify clear relationships theuse polyvinylchlorideas binder significantly improves composite. results research solve problem improving characteristics wood-composite expand Keywords: density, resistance.

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Dynamic Mechanical Analysis of Compatibilizer Effect on the Mechanical Properties of Wood Flour-High-Density Polyethylene Composites
In this study, effect of MAPE (maleic anhydride polyethylene) as the compatibilizer on the mechanical properties of wood-flour polyethylene composites has been investigated by using Dynamic Mechanical Analysis (DMA). Composites were made at 25% and 50% by weight fiber contents and 1% and 2% compatibilizer respectively. Controls were also made at the same fiber contents without the compatibilize...
