A safety helmet is a hat that protects the head from damage caused by impact, piercing, and squeezing. Hard hats can be categorized by material, form and location. The safety protection of Lanzhou Shunas below gives us a summary of the strengths and weaknesses of FRP helmets, and we hope to help our customers to buy hard hats!

The advantages of FRP helmets:

Lightweight and strong

The relative density is between 1.5 and 2.0, only 1/4 to 1/5 of carbon steel, but the tensile strength is close to or even exceeds that of carbon steel, and the specific strength can be compared with that of high-grade alloy steel. Therefore, it has excellent results in aviation, rockets, spacecraft, high-pressure vessels, and other applications that need to reduce its own weight. Some epoxy FRP's tensile, bending and compressive strength can reach more than 400Mpa.

Good corrosion resistance

FRP is a good corrosion resistant material and has good resistance to the atmosphere, water and general concentrations of acids, alkalis, salts, and a variety of oils and solvents. Has been applied to all aspects of chemical preservation, is replacing carbon steel, stainless steel, wood, non-ferrous metals.

Good electrical performance

It is an excellent insulating material used to make insulators. It can still protect good dielectric properties at high frequencies. Microwave permeability is good and it has been widely used in radome.

Good thermal performance

The thermal conductivity of FRP is low, and is 1.25~1.67kJ/(m·h·K) at room temperature. It is only 1/100~1/1000 of metal, and it is an excellent thermal insulation material. In the case of transient ultra-high temperature, it is an ideal material for thermal protection and ablative resistance. It can protect space vehicles from escaping high-speed air currents above 2000°C.

Good design

1 According to the needs, various structural products can be flexibly designed to meet the requirements of use, and the products can have a very good integrity.

2 Material can be fully selected to meet the performance of the product. For example, it can be designed to be corrosion-resistant, resistant to transient high temperatures, a product with a particularly high strength in a certain direction, good dielectric properties, and so on.
