Abstract

The invention discloses an ultra-high strength glass fiber reinforced thermoplastic resin composite plate. The composite plate comprises the following components in parts by weight: 40-60 parts of thermoplastic resin, 40-60 parts of continuous ultra-high strength glass fiber and 0.2-0.5 parts of silane coupling agent. The invention further discloses a preparation method of the ultra-high strength glass fiber reinforced thermoplastic resin composite plate. The ultra-high strength glass fiber reinforced thermoplastic resin composite plate disclosed by the invention has the advantages of high mechanical properties, relatively good flame retardancy, aging resistance and high temperature resistance, excellent comprehensive performances, low price and relatively high performance-price ratio.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a bidirectional continuous ultra-high-strength glass fiber reinforced thermoplastic resin composite plate and a preparation method thereof. Background technique [0002] Continuous fiber reinforced thermoplastic resin is composed of fiber and resin. Most thermoplastic resins have low tensile strength, but have high toughness and plasticity; fibers have high tensile strength, but are easily damaged and Not easy to shape and process. The combination of fiber and resin complements the defects of the two, so that the comprehensive performance of continuous fiber reinforced thermoplastic resin composites is greatly improved. Compared with traditional steel and aluminum, its density is about 1 / 5 of steel and about 1 / 2 of aluminum; the specific strength and specific modulus are also much higher than steel and aluminum alloys, so in terms of stiffness and strength Under the s...
