Identifying the Quality of Fiberglass Reinforced Plastic (FRP)
Release time:
2023/10/17
Fiberglass reinforced plastic (FRP) is a composite plastic made from glass fiber reinforced unsaturated polyester, epoxy resin, and phenolic resin as the matrix material. As a type of composite material, FRP has been widely used in various industries such as aerospace, railways, decorative architecture, home furniture, building materials, sanitary ware, and environmental sanitation engineering due to its unique performance advantages. So how can we distinguish the quality of fiberglass? 1. Material Selection The raw materials used in fiberglass are resin, glass fiber, and other auxiliary materials configured in suitable proportions. High-quality fiberglass uses high-quality resin with low viscosity, low exotherm, low shrinkage, fast curing, high compatibility, and bright gloss. 2. Comparison of Finished Products High-quality fiberglass products have no obvious cracks, fewer air holes, bright and pure colors, good transparency, excellent toughness, high strength, good surface finish, and long service life. In contrast, low-quality fiberglass products have visible cracks, more air holes, impure colors, and insufficient gloss. Their service life is also shorter. 3. Durability The true strength of fiberglass is also revealed during actual use. High-quality fiberglass may slightly darken in color after several years but remains intact without obvious damage. Low-quality fiberglass, however, cannot withstand the test of time; after a few years, it may show obvious damage such as corrosion, breakage, and air holes, and its shape may become uneven with severe color degradation and overall aging. Generally, high-quality fiberglass is expected to last for twenty years, while low-quality fiberglass may show signs of aging after just two years, leading to significant losses for customers. Therefore, we remind customers not to be tempted by low prices to choose low-quality fiberglass products, as this could lead to greater losses. Additionally, there are several other methods to identify the quality of fiberglass: 1. Dimensional tolerances (internal dimensions within grids, external dimensions) 2. Appearance (defects that should not be present: exposed fibers, whitening, pits, fractures, uneven fibers, etc.) 3. Barcol hardness 4. Concentrated load and uniformly distributed load 5. Resin content 6. The simplest and most practical method to identify fiberglass quality: place the fiberglass upright on a cement or tile floor; if you hear a crisp metallic sound, it indicates that the fiberglass is qualified. Beihai Yueda Fiberglass Products Co., Ltd. in Guangxi is a professional manufacturer of fiberglass products, and our products are well-received by users. We welcome inquiries.

As a type of composite material, fiberglass has been widely used in various industries such as aerospace, railways, decorative architecture, home furniture, building materials, sanitary ware, and environmental sanitation engineering due to its unique performance advantages. So how can we distinguish the quality of fiberglass?
1. Material Selection
The raw materials used in fiberglass are resin, glass fiber, and other auxiliary materials configured in suitable proportions. High-quality fiberglass uses high-quality resin, with low viscosity, low exotherm, low shrinkage, fast curing, high compatibility, and bright gloss.
2. Comparison of Finished Products
High-quality fiberglass products have no obvious cracks, fewer air holes, bright and pure colors, good transparency, excellent toughness, high strength, good surface finish, and long service life; while low-quality fiberglass products have cracks, more air holes, impure colors, and insufficient gloss. Their service life is also shorter.
3. Durability
The true strength of fiberglass will also be revealed in actual use. High-quality fiberglass will slightly darken in color after a few years, maintaining overall integrity without obvious damage, while low-quality fiberglass cannot withstand the test of time, showing obvious damage such as corrosion, breakage, and air holes after a few years, with less even shapes and severe color degradation, overall aging. Generally, high-quality fiberglass is expected to last twenty years, but low-quality fiberglass will show signs of overall aging after two years, leading to significant losses for customers. Therefore, we remind customers not to choose low-quality fiberglass products just to save money, as it may lead to greater losses!

3. Barcol hardness

5. Resin content
6. The simplest and most practical method to identify fiberglass quality: place the fiberglass directly on a cement or tile floor, and if you hear a crisp steel sound, it indicates qualified fiberglass.
