Pillared-montmorillonite is a new type of nano-porous materials formed by being calcined.
Pillared-montmorillonite can be used as an adsorption material for better performance, which can provide more larger pore structure characteristics[3] than zeolites (pore size of 8 ~ 9 Å [1]).
In order to investigate the effection of pH of solution, the solution’s pH is changed when the aging time is 3 hours and different Ti-pillaring agent are formed. 3.2 Preparation of Ti-pillared-montmorillonite Preparation of raw materials pillared montmorillonite using a real in Northeast bentonite, be made of sodium bentonite, Na-montmorillonite.
The raw materials producing pillared-montmorillonite is bentonite coming from certain estate in the Northeast.

The utilization materials that are made with aluminum alloy-fly ash (ALFA) is very valuable in terms of the economy compared with other alloys.
In general, experiments are used to study the performance of a process or system that is usually visualized as a combination of machines, methods, people and raw materials that affect the process of changing inputs into outputs.

Introduction Among cellular materials, aluminum foams are in attention because its provides a unique combination of properties such as very low density, high energy absorption under static and dynamic compressions, sound absorption and flame resistance [1].
Materials and Method Aluminum powders with particles size <35 um were mixed with spherical carbamide ((NH2)2CO) granulates with range of 1–5 mm sizes in a ball mill for 1 h according to the composition ratio listed in Table 1.

The composites materials based on the epoxy matrix and reinforcing fibers are extensively used in aircraft structures due to their high specific characteristics.
Introduction To achieve ever greater mechanical performance, innovative materials continue develop.
These materials are assembled by drilling and riveting and / or bolting, and hundreds of thousands of rivets or bolts are required for the assembly of an airplane.
We notice that the three curves of the three SCF materials have a similar appearance.
