Yes, fiberglass is perfectly compatible with epoxy resin. It is one of the most commonly used combinations for reinforcement, laminating, repair, and the manufacture of strong, durable composite parts.
The resin is applied with a brush or roller by progressively impregnating the fabric laid on the substrate. It is important to work in thin layers, remove air bubbles, and respect the resin/hardener mixing ratio.
For carbon fiber fabric, it is recommended to use a fluid, transparent epoxy resin. This ensures proper fiber impregnation and enhances the aesthetic appearance of the carbon, especially for visible parts.
Air bubbles can be minimized by working slowly, using a well-mixed resin, and maintaining a stable temperature. Using a debubbling roller or vacuum bagging helps achieve an optimal, professional result.
Yes, epoxy resin is compatible with aramid fiber. However, this fabric is more difficult to impregnate due to its structure. A fluid resin and careful application are essential to achieve a good result.
The thickness depends on the fabric weight and the number of layers. In general, the resin should just saturate the fibers without excess, in order to obtain a strong part without unnecessarily adding weight to the composite.
The number of layers depends on the final application: light reinforcement, structural part, or aesthetic purpose. One to two layers are sufficient for simple reinforcement, while technical applications require several stacked layers.
The ideal temperature is generally between 18 and 25°C. A temperature that is too low slows down curing, while a temperature that is too high can reduce working time and promote air bubbles.
Yes, hand lay-up is perfectly possible and can deliver excellent results. Vacuum bagging is an advantage for technical parts, but it is not essential for many projects.
The method consists of placing the fabric on the substrate, applying the resin progressively, then working the saturation with a brush or roller until the fabric becomes translucent.
