The invention provides an anti-ablation light bearing cover plate and a preparation method thereof. The cover plate is of a three-layer structure, wherein the innermost layer is a high-toughness structure bearing layer, the outermost layer is a thermal protection anti-ablation layer, and the thermal protection anti-ablation layer and the high-toughness structure bearing layer are bonded through high-temperature-resistant silicon rubber. According to the invention, the thermal protection anti-ablation layer and the high-toughness structure bearing layer are matched with each other, the thermal protection layer adopts an anti-ablation fiber cloth reinforced phenolic resin system, and the high-toughness structure bearing layer adopts a carbon fiber reinforced modified bismaleimide resin system, so the overall weight of the cover plate is effectively reduced on the basis of ensuring ablation resistance and high mechanical properties.
本发明提出一种抗烧蚀轻质承载盖板及其制备方法。盖板采用三层结构,最内层为高韧性结构承载层,最外层为热防护抗烧蚀层,热防护抗烧蚀层和高韧性结构承载层之间采用耐高温硅橡胶进行粘接。本发明采用热防护抗烧蚀层与高韧性结构承载层相互配合,且热防护层采用抗烧蚀纤维布增强酚醛树脂体系,高韧性结构承载层采用碳纤维增强改性双马树脂体系,在保证耐烧蚀和高力学性能的基础上,有效的降低了盖板的整体重量。
