This research has been studied and created the ceramic armor plates with composite materials that been proceeded from drying compression process with mold. Al2O3 that use for compression forming has been analyzed by SEM and XRD. It showed that compound and powder particle led to 5 microns-sized. It had flat circle shape of colundum Al2O3 and hexagonal crystal system. Upper punch of molding has designed and analyzed by FEA to 2 forms first form was the end-point had flat face and second form was the end-point had a convex. Upper punch had been made from AISI 52100 with 64 HRC ceramic armor plate had been produced by compression at 1000 kN which had hexagon side shape of width 25.98 mm for each side or height between parallel side of 45 mm. Al2O3 had been compressed to investigate the distribution of relative density for the height after compression of 15 and 30 mm by analyzing 4 cases that consist of 1.) a case of smooth face of upper punch which has green compact of 15 mm height 2.) a case of convex face of upper punch which has green compact of 15 mm height 3.) a case of smooth end face of upper punch which has green compact of 30 mm height 4.) a case of convex face of upper punch which has green compact of 30 mm height. The result of this study is to propose the distribution of relative density on horizontal axis as it is a relative radius and vertical axis is a relative distance from the upper punch that is an axis of moving down action. This study found that the distribution of relative density form had analogous form for these 4 cases the density had few differences and had high value at the town edge of green compact due friction between die wall and upper punch. The ceramic armor plate has been set up on UHMWPE fiber plate and used special silicone to connect them together then will get the NIJ 3 standard of ceramic armor plate with Composite materials

Quality control of dyeing and finishing of Water Hyacinth yarns and their transformed materials for commercial was a main objective to establish the dye database of synthetic dye and natural dye. The dye database was a data for quality control in dyeing process of raw material as Water Hyacinth yarns also it resolved the un-repeatability dyeing problem. Reactive dye was used for synthetic dye database creation on dry Water Hyacinth yarns at 80oC for 30 minutes. Red as Hicion Red He-3B yellow as Hicion Yellow HE-4RN Blue as Hicion Navy Blue HER 150% and black as Hifix Black KNN were the represent synthetic dye and Sodim sulphate 20 g/l and sodium carbo nate 20 g/l were used as auxiliaries. The other hands the natural dye database was forming from Ebony tree Caesalpinia sappan and Turmeric. They were dye on dry Water Hyacinth yarns at 80oC for 30 minutes and Sodim sulphate 20 g/l was the auxiliary. Whereas Butterfly pea were dye at 80oC for 30 minutes by Sodim sulphate 20 g/l and sodium carbonate 20 g/l were the auxiliaries. The whole dye database was defined the totally in Primary Secondary and ternary dye cycle. The transfer knowledge was distributed to the enterprise at Nakhon Prathom Provincd as “Chumchonjaksanpaktobchawha Bann klongnokkratum”. The topics were “How to establish the synthetic and natural dye database” “Water repel lent finishing” and “developed and transformed the Water Hyacinth to products”. The target group was very satisfied in this topic as 4.39. In the result the proportion between economic and social factor by the income increasing in 1 year was 5.04. So the research project was achievement.

This research is to study and develop natural pulp materials for packaging. This is the agricultural waste. To benefit commercially To build capacity and capability in economic development and environmental conservation Is the creation of packaging work Formed in sheets and shapes using natural materials such as mulberry paper pineapple paper. And banana paper Then design and create the packaging. To test the properties. According to the standard packaging. They also sought satisfaction in the form and use of natural pulp materials. Include the packaging according to the case study. Research indicates that When developing pulp quality The banana paper can not be printed. Can print lines. But screen printing is not suitable for banana paper. Foil printing case when mulberry paper and pineapple paper Foil printing Printing lines Can be done well on mulberry paper and pineapple paper. Death images can be printed on all three types of paper but the screen is not good. Sealing material from natural pulp onto corrugated paper. From the test it was found that the amount of adhesive that was suitable for sealing was between 20-30 mg. If the adhesive was less than 20 milligrams only mulberry paper was sealed. The amount of glue at 50 milligrams is the amount of glue is too high causing all three types of paper to rot. Because of the adsorption of glue to the pulp. Packaging material from natural pulp. Fold of banana paper that does not pass the test. The banana paper is high in strength. When folding the packaging causes the pulp to split along the crease. Can not be molded. Evaluation of the satisfaction with the form and use of packaging materials from natural pulp. It was found that the average value of paper pulp suitable for packaging materials from natural pulp was the most agreeable paper. Secondly paper shreds are very popular and the last one is banana paper. Moderate agreement

The Study Natural Materials to Product Design for Tree Planting. Studying natural materials To design a product for a tree Study on utilization of natural materials. Study and development of natural materials and ratios of various materials suitable for planting products. And compare the properties of natural materials. Made to plant products. To achieve the objectives of the research. Researchers conducted various researches. And present the results of data analysis. The best ratio is natural material: cement: 1: 1.5: 2 water: 695 kg / m 3 Water absorption test of various materials mixed with all three types of materials. Water absorption of soil and glue mixture is best absorbed. The absorption was 88%. Experiment on the swelling of natural materials mixed with all three types of materials. The test results showed that the swelling rate of cement mixed materials. The smallest swelling was 0.332 millimeters (0.08 millimeters). The questionnaire was used to collect data from 150 questionnaires. Statistical analysis is used to determine frequency. Of the 150 respondents about 94.7% of the rubber tree structure was found. 65.3% of the products obtained from the rubber leaves were 49.3%. There were 5 - 10 types of rubber leaves. The 80 respondents commented that most of the products of the rubber leaves were flowers (53.3%). The answer was 132 respondents representing 88%. On the durability of natural products 49.3% said that the products of natural materials are durable medium. There were 10 - 50 species of natural materials 52.7% of them had opinions about 51% of natural plant products. 59% had good quality 53% were good in natural materials 53% satisfied with the color of natural plant products 60% satisfied with the products. At the same time 47% of the products were planted in natural materials 47% of which were of good quality. 98% of tree planting products. The research found that people are interested in products for planting trees from natural materials. It is a combination of natural materials to create a new material with unique patterns. It can also be developed into more products.

This research study the effect of pozzolanic materials on light weight concrete by replacement cement with fly ash and Meta kaolin which affect the properties of concrete by using pumics aggregate. Coarse in aerated concrete and consider mechanical properties. Aerated concrete replacement cement by fly ash 20% 35% and 50% respectively and meta-kaolin is replaced. From the results it was found that the compressive strength of light weight concrete at 28 days w/b = 0.55 was higher than that of every 14 days of cement and cement cement replacement by fly ash 50% highest value compressive strength. More than all the ingredients replaced with fly ash and Meta kaolin. When considering the flexural strength of replacement cement with 10% by Meta kaolin the maximum flexural strength of 80 ksc was higher than that of control concrete and all other ingradient. Experimental tensile strength at 28 days result found that replacement cement by fly ash at 35% gave the highest tensile strength of 28 ksc and gave higher tensile strength than all other ingradient. From the impact strength test at age 28 days it was found that the replacement cement 35% by fly ash gave the highest impact strength of 92.00 joule than the 20% and 50% respectively and higher impact strength than that of all kaolin. Except for control concrete.
