    Abstract
    The research aimed to carry out an experiment on the production of composite objects formed by matrix and reinforcement materials made from rubber tree sawdust to carving, to test the physical properties and graving of the composite material, and to design the wood carving and made prototypes. The population and the sample were 1) the production of composite materials from rubber tree sawdust. (mixing of matrix and reinforcement materials, and forming) 2) 60 handicraft buyers who were tourists in Baan Tawai village and Walking Street at Chiangmai. The data were collected by 1) the results recorded material. 2) composite material tests use physical properties and engraving plate material. 3) using questionnaire for handicraft buyers, and 4) the evaluation prototypes. The data were analyzed by percentage, mean and standard deviation. The results were as follows: 1. The analysis and the experimental results showed that 1) three formulas were obtained: CM1, CM6 and CM9 formulas - Latex adhesive, plaster, rubber tree sawdust, clean water, sodium benzoate and iron oxide. 2) sheets of the composite materials CM1 of 29.85 cm. x 39.85 cm. x 22 mm., CM6 of 29.75 cm. x 39.75 cm. x 21 mm. and CM9 of 29.70 cm. x 39.70 cm. x 20 mm. 3) testing the physical properties of the composite material showed that CM1 formula a bending strength (27.50 ksc.) and hardness (0.56 HB.) than CM6 a bending strength (24.40 ksc.) and hardness (0.53 HB.) while CM9 a bending strength (16.93 ksc.) and hardness (0.61 HB.) were obtained, 4) testing the engraving plate material CM1 formula (  =2.35) and the second (  = 2.40) were at a fair level while the third (  = 3.00) was medium. 2. The analysis of the customers’ requirement showed the purposes to buy the product ranking the highest to the lowest of preference – wood carved base relief, round relief, high relief and incised relief respectively. Most of the customers required that home decoration items, and decorated living room area in the wall. Also, they should be finely designed and locally unique. The products should be made from natural material in authentic color and local patterns. The object on wood carving should be natural and lifestyle stories. Carved wooden frame should be freeform and rectangle shapes. 3. The research of the product design and development process using composite material from rubber tree sawdust revealed that 1) the concept of product design and development should be based on the factors affecting the designing. 2) In terms of materials and production method, the characteristics and size of the composite materials to be used should be taken into account. 3) The information of customers’ requirement was needed. 4. The sample product assessment showed that the overall satisfaction of the product design experts, manufacturers, and handicraft sellers was at a very good level is waste of adding value, and environment friendly ( X =4.53), the rate of satisfaction was at a much level as follows: the first, can be used (accessories/souvenirs), and appropriate choice of wood substitute materials ( X =4.40); the second, can be taken as OTOP products, and overall satisfaction ( X =4.33); the third, beautiful appearance (patterns and style), and being marketable ( X =4.20)
