Nowadays an automotive industry steadily has been growing and playing a major role on economy development for many years. The crash box is one of the most important parts for safety but it was found that the crash boxes manufactured domestically are not met international standard requirements. This is due to process and material limitation. This process for automotive safety test requires high budget and there is unclear approach for specific test. Therefore a study of crash boxes referred to energy absorption project was conducted as the alternative materials for product. Consequently this project was aimed to design and test crash boxes which made from the diversity of the alternative materials such as aluminum aluminum reinforced by foam resin reinforced by fiberglass resin reinforced by water hyacinth and resin reinforced by water hyacinth and husk. In addition it was also emphasized in studying energy absorption behavior and physical deformation of crash boxes after dynamic and static energy being applied. The experimental works were applied for these tests in partly referenced to US NCAP and ECE R29 standard for automobile collision test. Testing all types of crash boxes indicated that the aluminum reinforced by foam type was able to absorb energy at 189 MJ/m3. It is higher than resin reinforced by water hyacinth and husk at 1 MJ/m3 as 188 times. Furthermore the comparison of the energy absorption (per unit volume) between the aluminum reinforced by foam type and the steel type from the previous project equivalent 20 MJ/m3 found that it is 8.45 times of difference. While the front impact test was not successful because the size of crash boxes was not suitable for the energy volume. It was a cause for non-available calculation of energy absorption value.

The purpose of this research were 1) Development and production of the cotton fabric suitable for use in the kitchen apparel chef Thailand 2) test the suitability of the fabric from the fabric used to make kitchen apparel chef in Thailand. Tools used in the study are the fabrics used to make clothing chef woven pattern 2/1 for 3 structures 1) Cotton100 2) Polyester Microfiber and 3) TR. Being three fabrics to test of the fabric aspects of the durability of color to light color fastness to washing colorfastness to perspiration strength of the yarn yarn number weight yarn yarn twist yarn thickness weaving and resistance to abrasion properties of the fabric the effect of moisture. The quantitative data were analyzed by descriptive statistics from assessment and feedback of chef’s uniforms by the establishment of a laboratory in the kitchen by cooking in Thailand 15 Thailand kitchen. The chefs were wearing 3 sets each 5 days per a types of them for 15 days. Each of chef’s uniform made from the different types of fabrics. Data analysis and interpretation with the average 5 level content analysis and evaluation. Data analysis in descriptive and narrative. The results founded that Chef of food establishments restaurants Hotel and restaurant with 15 people most of the food is the leader in working kitchen (Executive chef) the timetable of working in the evening in the Thai-kitchen from 12:00 to 21:00 o’clock for 5 days a week. It’s about environments of Thai-Kitchen The temperature of the kitchen operations in restaurants and room temperature and after the experimental wear three types of 15 day Chef has been satisfied in sample number 2. It is Micro Fiber fabrics because there is good ventilation not get heat easy to clean fabric good reflect of oil or anti-oil water absorption and drying rate of the normal range. Micro Fiber fabric when Chef wear it not heavy able to wear at all times. The results of the test and analysis Micro Fiber Cloth material that is resistant to very light. The fabric is not easily broken. Strength and abrasion resistance as possible. It is oil on fabric and yarn on the oil splash in the Kitchen. Including the ability to absorb water and the distribution of water as much as possible.
