The salient and versatile features of phenolic resins provide favorable comparisons between them and other thermosetting resins as well as thermoplastic products: thermal behavior, high strength level, long term thermal and mechanical stability, fire, smoke and low toxicity characteristics, electrical and thermal insulating capabilities, cost performance characteristics. The technical content of the book describes significant new phenolic resin chemistry, transformations and recent mechanistic pathways of resole and novolak cure. A vastly expanded treatment of selected application areas consists of wood composites, insulation/textile felts, molding compounds, paper/fabric impregnation, foundry, abrasives, friction and refractory. New applications with up-to-date developments include high performance and advanced composites, imaging/photoresist and carbon/graphite areas. Also included in detail: Standardized test methods important for ISO 9001 ff certification.

Natural Fiber Composite
81,30 € *
ggf. zzgl. Versand

Natural fibres like jute have attracted worldwide attention as a potential for making reinforced polymer composite because of their low price, low density, light weight, easy processing ability, renewability, recyclability and non-abrasive, non-hazardous and bio-friendly characteristics. In the present write up, jute fibres in the form of Slivers have been reinforced with epoxy resins to prepare high strength composites. An attempt has been made to improve upon the mechanical performance of the composite while trying to increase the percentage of fibre loading to have a low cost material.

Morphological Changes in Banana Fiber Composites
41,10 € *

Composites have become so vital due to their high effective stiffness and strength, availability, low cost, specific strength, better dimensional stability and mechanical properties, eco-friendly and biodegradable as compared to plastics and fibers. Among all the property now a day's researchers concern is more on the biodegradable properties due to strict environmental rules and regulations. However always the non-biodegradable composites have more strength and stability, researchers adding various additives, blending fibers and resins which are biodegradable to bring the strength and stability on par with non-biodegradable composites.

Biosorbent from Neem (Azadirachta indica) leaves

Removal of organic and inorganic pollutants from wastewater by adsorption on activated carbon and synthetic resins has been widely studied. Though activated carbon is an ideal adsorbent for organic matter due to its organophillic character, high cost of preparation and regeneration is a limiting factor for their large-scale use in wastewater treatment. This has prompted the use of many novel materials as adsorbents. The present work was aimed at developing a low cost adsorbent from the mature leaves of the Neem (Azadirachta indica)tree. The objectives were to convert dry, mature Neem leaves into a powder (Neem Leaf Powder, NLP), characterize the adsorbent (NLP) by spectroscopic and other methods, test the effectiveness of NLP as an adsorbent for removal of micro-pollutants such as dyes (methylene blue, Congo red, brilliant green) and metal ions (Cd(II), Cr(VI) and Pb(II)) from an aqueous medium, and determine the influence of various factors such as concentration, pH, temperature, and agitation time, etc., on adsorption. Both batch and column adsorption processes were applied with significant achievements.

Polymers are enchantment for modern mechanized civilization because of the versatility of their applications. These materials can be tailored as per desired applications. However polymer science as a coherent subject is barely few decades old. The importance of polymers had increased because of light weight, low cost, excellent chemical resistance, anti corrosive nature and easy processbility. Polyurethane is the most versatile group of polymers next to unsaturated polyester resins. These materials are important block co-polymers. Properties of end product can be designed according to it's application. Due to potential large volume of applications combined with high versatility in the properties, these materials require a thorough understanding of synthesis and properties as well as update of knowledge. Polyol synthesis from renewable resources and their possibility for industrial polyurethane application has gained a considerable attention in recent times.The polymer known as polyurethanes are widely used in the fields of daily life due to their excellent wear resistance, toughness, mechanical properties and chemical resistance.
