Abstract
The movement to introduce FRP, especially CFRP in automobiles, is accelerating in automobile related companies, with the aim of improving fuel economy and reducing the price of raw materials by reducing the weight of automobiles. In this study, we have succeeded to reduce the proportion of commonly used powder binder from the existing glass mat weight ratio of 11% to 6.2% in the preparation of a mat sample exhibiting a tensile strength of 4.5 kg by the new mat dry production method. At the same time, we succeeded in preparing the 80 th mat with less than 4% of the new mat binder (NBL - 113) developed by our company, using a bundle of 100 glass fiber bundles (white arrow). By applying this technology to automotive body FRP molding, energy saving and price reduction of automobiles can be expected.
