Carbon fiber-reinforced composites (CFRCs) are increasingly utilized in a wide variety of fields such as aerospace, automotive, marine, and wind energy sectors, partially due to the excellent and unique properties of CFs such as lightweight, higher specific strength, and corrosion and environmental resistance.1–5 However, the essential properties of CFRCs are often limited by the intrinsically poor properties of the matrices. To maximize the function of CF, the selection of the matrix is indispensable and highly important. Compared with traditional thermosetting resins, thermoplastic matrices are somewhat beneficial to recycle, reuse, and protect the environment, which encourage trends of increasing applications.6–11 However, the heat resistance and mechanical properties of common thermoplastic matrices are often reported to be not competitive enough, which may limit the increasingly restrictive requirements of practical applications. These disadvantages can be partially made up by the use of new materials with improved heat and mechanical properties. For example, poly(ether-ether-ketone) (PEEK), a thermoplastic resin with good heat resistance and high mechanical properties, can be viewed as a successful representative.12 However, the processability of PEEK is somewhat difficult, owing to its high melting temperature.13 In this respect, poly(ethylene 2,6-naphthalate) (PEN) may become an ideal matrix of CFRCs owing to its favorable processing conditions and excellent performance.

轻质高强度碳纤维增强聚(乙烯-2,6-萘)固体和泡沫复合材料的制备

碳纤维增强复合材料(CFRC)越来越广泛地用于航空航天,汽车,船舶和风能领域等各种领域,部分原因是CF的出色和独特的性能,例如重量轻,比强度高和耐腐蚀和环保。1–5但是,CFRC的基本属性通常受到矩阵固有的较差属性的限制。为了最大化CF的功能,矩阵的选择是必不可少的并且非常重要。与传统的热固性树脂相比,热塑性基质在一定程度上有利于回收,再利用和保护环境,这鼓励了日益增加的应用趋势。6-11然而,经常报道普通热塑性基体的耐热性和机械性能不够竞争力,这可能限制了实际应用中越来越严格的要求。这些缺点可以通过使用具有改善的热和机械性能的新材料来部分弥补。例如,聚醚醚酮(PEEK)是一种具有良好耐热性和高机械性能的热塑性树脂,可以被视为成功的代表。12然而,由于其高的熔化温度,PEEK的可加工性有些困难。13在这方面,聚(2,6-萘二甲酸乙二醇酯)(PEN)由于其良好的加工条件和出色的性能,可能成为CFRC的理想基质。
