The present study presents a new methodology developed for an analytical model of a composite fuselage. It also presents finite element analyses of a simplified model and comparisons with more complete models. These comparisons show that there is a very good correlation between both models for the cases studied. Therefore, the applicabilty of the proposed procedure was demonstrated. Based on fi...

On the industrial side, selection of materials for a product produced by company must be following function and purpose product. There are many types used various companies in manufacture product, one which is aluminium. This study aims to determine effect temperature variations 3% Al-TiC Composite Heat Treatment 350°C, 450°C, 550°C on mechanical properties microstructure with cooling slope met...

The fabrication of the Al2219 + Si3N4 composites was done by means stir casting process. specimen subjected to microstructural studies. density employed in has been evaluated. Generally, increases as weight percent increases. TGA and DTA were performed at temperatures ranging from 30°C 800°C, with some mass loss noted well thermal stability an AA2219 matrix improved. Under various parameters ap...

Polymer-clay nano-composite materials, in which nano-meter thick layers of clay dispersed in polymer matrix, have generally higher mechanical properties than normal polymeric materials. A new three-dimensional unit cell model has been developed for modeling three constituent phases including inclusion, interphase and matrix. The total elastic modulus of nano-composite is evaluated.  Numerical r...

Porous materials in general have received great attention from the last century. The development of new porous materials and the preparation of new composites based on porous materials is a subject of interest. The development of porous silicon based optical composite materials opened up new ways of incorporating optically active sol-gel materials into porous silicon. High purity silica optical...

PTFE-based coatings have been widely used, for example, on aluminium moulds for moulding of polyolefin packaging materials for its non-stick property. However, these coatings do not meet the users’ scratch resistance and durability requirements. This paper describes a preliminary study on the synthesis and characterization of a PTFE/sol-gel composite coating material which combines the required...

the use of methods employed for estimating the strength and toughness of composites reduces the trial-and-error in their design. the strength of interface between reinforcement and matrix and the effective surface of pulled-out particles have great influences on toughness and strength of these composites. in this study, a model was proposed to estimate the interface strength and matrix strength...
