The engine guard is a core underbody component, enduring harsh working conditions including high engine heat radiation, gravel impact, mud & water erosion and constant vibration. Traditional steel guards suffer heavy weight, rusting and abnormal driving noise; ordinary unreinforced nylon lacks heat resistance and rigidity, prone to deformation and cracking over long-term use, failing to meet automakers’ dual demands of lightweight design and durability.
Glass fiber reinforced nylon has become the dominant material for engine guards of both fuel and new energy vehicles, thanks to its balanced comprehensive performance.Its heat deflection temperature ranges from 180℃ to 250℃, resisting engine radiant heat to prevent thermal softening and aging damage.
It delivers outstanding mechanical properties: tensile strength of 200 MPa, flexural strength of 270 MPa, and room-temperature impact strength of 20 kJ/m². It resists cracking when hitting stones or road obstacles, fully protecting delicate underhood parts such as oil pans, pipelines and sensors.
Compared with metal guards, this material boasts remarkable lightweight advantages to cut vehicle weight and energy consumption. It also features great acid & alkali resistance and mud-water corrosion resistance without rust perforation. It enables smooth injection molding for integrated complex guard structures, streamlining manufacturing processes to fit mass automotive production. The material maintains stable dimensions with minimal shrinkage, ensuring consistent assembly tightness under alternating high and low temperatures.
Against the trend of upgraded material selection for auto underbody parts, glass fiber reinforced nylon perfectly aligns with automakers’ R&D goals of lightweight, low-noise and long-lifetime components. Conventional plastics cannot balance heat resistance and impact resistance, while metal parts add excess weight and raise anti-rust costs. This nylon material combines high strength, high heat resistance, corrosion resistance and light weight, balancing performance and production costs.
