Options include improved resistance to extremely alkaline conditions by incorporation of a synthetic surfacing veil, and reduced flammability by use of a fire-retardant resin system.
Table 1 - Characterization of reinforcements and physical properties for high-strength fiberglass sheets.
High-strength fiberglass sheets are manufactured in three "types". The difference between the "types" lies in the kind of fiberglass reinforcement incorporated into the sheet, and the resulting fiberglass content and physical properties, as indicated in Table 1.
Sheet sizes and thicknesses available for each "type", and a review of common applications are summarized in Table 2.
Sheets can be supplied that meet performance criteria of all grades of the MIL-P-17549 specification for marine structural sheets. Sheets can be supplied that exibit burning characteristics meeting criteria of the MIL-R-21607 specification.
Table 1 | Type 40 | Type 60 | Type 70 |
|---|---|---|---|
Reinforcement | chopped mat | woven roving | fiberglass fabric |
Nominal fiberglass content | 40% by weight | 60% by weight |
|
Tensile strength, psi | 20,000 | 35,000 | 30,000 |
Flexural strength, psi | 30,000 | 32,000 | 37,000 |
Flexural modulus, psi | 1.2 million | 1.6 million | 2.0 million |
Compressive strength, psi | 20,000 | 20,000 | 25,000 |
High-Strength fiberglass sheets are used in many applications, including industrial access covers, equipment mounting plates, corrosion-resistant and impact-resistant liner panels, stiffeners and batten strips, baffles in water treatment facilities, and many marine and shipboard uses.
