Program : Automotive Technology to Sustain Competitiveness (B4-1)
At present, hand lay-up and spray-up are predominant methods for making composite automotive parts in Thailand. With long cycle time, these methods are only deemed suitable for parts below 1,000 pieces. For high-volume parts, Resin Transfer Molding (RTM) is more viable for productions. However, part quality from RTM strongly depends on several issues such as resin and fiber quality, bonding strength between resin and fiber, etc. In this proposed work, many RTM experiments will be conducted in order to gain more knowledge about the effects on composite caused by resin viscosity, rate of reaction, fiber quality, fiber layout and resin injection condition. Also in this study, an on-line monitoring system will be used to evaluate and reassure product quality minimizing problems from bubbling and resin shrinkage ultimately obtaining high-quality products suitable for automotive exteriors.
