Flame Retardant Plain FRP Sheet For RV Electrical And Electromagnetic Properties

FRP Flat Plate Use Of RV Electrical And Electromagnetic Properties Flame Retardant

The properties of fiberglass fiber reinforced plastic plates (glass fiber reinforced plastic plates) are determined by their composite material characteristics, covering multiple dimensions such as physics, mechanics, chemistry, and electrical. The specific details are as follows:

1. Physical properties

density

The density is usually 1.5-2.0g/cm³, which is much lower than steel (7.8g/cm³) and aluminum alloy (2.7g/cm³). It is a lightweight material and can significantly reduce structural weight load.

Appearance and texture

The surface can be smooth, matte or textured through process processing, and the colors can be customized (such as white, gray, color, etc.), both functional and decorative.

Light transmittance

Some models (such as using transparent resin matrix) have a certain light transmittance and can be used in lighting scenarios (such as greenhouses, lighting sheds), but the light transmittance is lower than that of glass.

Heat resistance

Short-term use temperatures are generally -50℃ to 120℃ (depending on the resin type), high temperature resistant models (such as phenolic resin matrix) can withstand higher temperatures (above 200℃), but long-term high temperatures may lead to performance degradation.
Water absorption

The water absorption rate is low (usually <0.5%) and it is not easy to expand or deform due to water absorption in humid environments.

2. Mechanical properties

strength

Tensile strength: 300-500MPa (some high-performance models can be close to steel), far exceeding wood and ordinary plastic.
Bending strength: 200-400MPa, impact resistance is better than glass and ceramics, and is not prone to brittle cracking.

rigidity

The rigidity is moderate, and it can be lifted by adding reinforcement ribs or adjusting the fiber laying method to avoid excessive deformation when under stress.

toughness

It has a certain elasticity, is not easy to break when impacted by external forces, and can absorb part of the impact energy (better than brittle materials such as glass).

Wear resistance

The surface has medim wear resistance and can be enhanced by adding wear-resistant fillers (such as quartz sand) or coating treatment, suitable for general friction environments.

3. Chemical properties

Corrosion resistance

It has good resistance to corrosive media such as acids, alkalis, salts, and organic solvents (depends on the type of resin):
Polyester resin matrix: resistant to general acid and alkali, suitable for ordinary industrial environments.

Vinyl ester resin matrix: resistant to strong corrosion and is suitable for harsh environments such as chemicals and marine.
(No electrochemical corrosion with metals, better than steel and aluminum alloys)

Aging resistance

It has strong resistance to ultraviolet rays and atmospheric aging. It is not easy to crack, fade or powder when exposed outdoors for a long time. Its service life can reach 15-30 years (need to be combined with anti-aging additives).

Weather resistance

It can adapt to different climatic conditions, and has stable performance under alternating high and low temperatures, and is not easily damaged by freeze-thaw cycles.

4. Electrical and electromagnetic properties

Insulation

It is non-conductive and has a high volume resistivity (usually >10¹⁴Ω・cm), and is an excellent electrical insulating material, suitable for distribution boxes, insulating brackets, etc.

Magnetic resistant

It is non-magnetic, will not be affected by magnetic fields, nor will it interfere with the surrounding magnetic fields. It is suitable for medical, precision instruments and other scenarios.

5. Processing and use properties

Forming flexibility

It can be made into different sizes (such as large-sized flat plates) and shapes through hand pasting, molding, pultrusion and other processes, supporting secondary processing of embedded connectors, openings, etc.

Maintenance

The surface is not easy to accumulate dirt and is easy to clean; it does not require anti-corrosion or rust removal treatment, and the maintenance cost is low.

Environmental protection
No toxic substance release (food-grade resin models can contact food), and can be recycled after being discarded (partial processes).
