“…Many researchers have attempted to overcome the brittle nature of BMI via modification of its chemical structure by adding other chemical groups [12][13][14][15]. Another successful approach is the use of chain-extended high-molecularweight prepolymers prepared by the Michael addition reaction of BMIs and diamine [16][17][18][19][20][21].…”

This paper presents an experimental study of the influence of the addition of aromatic diamine (MDA) to bismaleimide (BMI) resin on the crystallinity, solubility, melting temperature, and mechanical properties of BMI/carbon composites. The modified BMI was prepared through the chain extension with MDA via Michael addition reaction with molar ratio of 3 : 2 (BMI : MDA). Both modified and unmodified BMI were characterised for chemical structure, crystallinity, melting temperature, mechanical property, and morphology and fracture behaviour using FTIR, XRD, DSC, UTM, and SEM, respectively. The FTIR results revealed the formation of polymeric chain due to the broad N-H absorption. The modified resin was semicrystalline in nature having low melting temperature and hence showed good processibility. The modification of BMI resulted in decrease of pores and increase of tensile, flexural, and impact properties of the composites. Also, SEM studies of the tensile fractured specimens revealed that modification of BMI resulted in improved resin/fibre interfacial strength.

“…In addition, polar carbonyl groups cause chain stacking, making energy dissipation difficult and the thermosets prone to fracture. [ 58 ] Matrimid 5292 is the current benchmark BMI/polyimide system and represents the second‐generation class of “toughened” BMIs with superior physical properties. Produced by Ciba Geigy and Huntsman, it consists of a combination of 4,4′‐bismaleimidodiphenyl methane (BDM) and diallylbisphenol A (DABA) ( Figure ).…”

The aerospace industry has been benefiting from the utilization of polymer materials since fibre reinforced polymer composites (FRPC) offers high performances at low densities compared to metals. In a way, FRPC innovated lightweight matter engineering and provided aviation as a public transport method. Since their first integration into structural parts, FRPC experiences an exponential growth over years and receives a special interest from manufacturing engineering. While FRPC today is a major focus in engineering, design of polymer matrix relies on polymer chemistry. However, aircraft materials are facing a pressing issue related to sustainability, since their environmental footprint is at alarming level. In this review, commercial thermosetting polymer composites employed in aircraft structures will be exhibited from chemistry perspective by depicting starting products and curing reactions. The potential of chemistry to architect next‐generation sustainable FRPC for structural parts by means of utilization of sustainable feedstock, energy‐efficient processing and recycling will be deciphered.This article is protected by copyright.

“…The high degree of crosslinking is responsible for the excellent elevated temperature performance of these materials, however it is also the reason behind the biggest drawback associated with BMIs: the cured polymers are brittle, with low fracture toughness. While this is also the case for many other thermosets, such as multifunctional epoxies, the issue is exacerbated in BMIs by the presence of polar carbonyl groups, which leads to ordered stacking of the polymer chains and less opportunity for energy dissipation [13]. Consequently, the drive to reduce the inherent brittleness of BMIs features strongly in many published research studies.…”

ABSTRACT:The chemistry of bismaleimides (BMIs), their blends and copolymers is reviewed critically with particular emphasis placed on the development of the field after 1990, which was marked by several comprehensive review articles. A general introduction to the structure property relationships of BMIs is presented, outlining the development of the preparative chemistry, and the early strategies adopted to address the inherent brittleness of the cured 'first generation' BMI polymers. 'Second generation', diallylbisphenol-toughened BMIs, form the basis of the benchmark commercial systems, and the polymerization mechanism is discussed. The current review is placed in context, addressing the issues of cost, processing and precursor toxicity, the major barriers to wider acceptance of BMIs. The main body of the review evaluates a number of observations made by Dr Horst Stenzenberger in 1990, for the future development of BMI technology. Hence, the synthesis of novel bismaleimide building blocks, incorporation of new thermoplastics and additives, and blending with new thermosetting comonomers are all discussed in detail. The aforementioned review had been written before the concept of nanocomposites or shape memory polymers had been explored with BMIs, but the fields have since grown (especially in the case of the former topic) and are reviewed herein. The application of BMIs to continuous fibre composites is one of the proposed fields of commercial development. The topic falls a little beyond the scope of the present review of BMI chemistry, and is the subject of another publication, but a brief discussion of the most recent developments is presented. The review is concluded with some thoughts about the future outlook for BMI chemistry.
