When using fiberglass mats on boat floors, the following types are typically chosen:
Chopped Strand Mat (CSM): This type of fiberglass mat consists of short cut glass fibers randomly distributed and bonded into a mat. It has good strength and corrosion resistance and is suitable for laminating hulls and floors.
CSM: Chopped fiberglass mats are made by randomly distributing short chopped fiberglass fibers and bonding them into mats using an adhesive. These short fibers are typically between 1/2“ and 2” in length.
Continuous Filament Mat (CFM): This type of mat is formed by continuous glass fibers, and its strength and corrosion resistance are higher than that of the chopped mat, which is suitable for more demanding applications.
Multi-Axial Fiberglass Mat (Multi-Axial Mat): This type of fiberglass mat is formed by laying and bonding multiple layers of glass fibers together in different directions, which can provide higher strength and impact resistance, and is suitable for hull parts that need to withstand multi-directional forces.
The following factors should be considered when selecting a fiberglass mat:
Application: the loads, wear and tear that the boat floor needs to withstand and the environmental conditions that may be encountered (e.g. salt water corrosion).
Construction process: The material selected should be compatible with your resin system and construction techniques.
Performance requirements: including strength, rigidity, corrosion resistance, impact resistance, etc.
Cost: Select cost-effective and suitable materials according to your budget.
In practice, it is also common to apply resins (e.g. polyester or vinyl ester resins) to fiberglass mats to make strong composite laminates. It is recommended to consult a professional material supplier or manufacturer before purchase and use to ensure that the best material for your specific needs is selected. Also, ensure that relevant safety codes and operating guidelines are followed during the construction process.
