UV etched random copolymer membrane coated PBO fibers/cyanate ester wave-transparent laminated composites

Cross-Linked and Rigid Polyimide Composite Foams with Prominent Fire Resistant, Thermal Insulating, and Wave-Transparent Properties

“…Radar-wave-transparent composites should not only have prominent structural strength, stiffness, and environmental resistance but also possess low dielectric loss characteristics to ensure the stable operation of the radar antenna system in a noninterference environment. 1,2 Especially in the aerospace field with a complex environment, antennas are faced with various environmental challenges such as high temperature, shock, and noise. Therefore, fairing or wavetransparent materials are urgently needed to protect the antenna and achieve stable communication.…”

“…With the rapid development of the aerospace industry, advanced electromagnetic wave-transparent composite materials are urgently needed for radome as electromagnetic windows to ensure the stable communication of radar antenna with the base station. Radar-wave-transparent composites should not only have prominent structural strength, stiffness, and environmental resistance but also possess low dielectric loss characteristics to ensure the stable operation of the radar antenna system in a noninterference environment. , Especially in the aerospace field with a complex environment, antennas are faced with various environmental challenges such as high temperature, shock, and noise. Therefore, fairing or wave-transparent materials are urgently needed to protect the antenna and achieve stable communication. , Advanced polymer foams consisting of three-dimensional porous microstructures usually show low thermal conductivity and low density, endowing them to be promising candidates as radar-wave-transparent materials.…”

Recent applications of electrical, centrifugal, and pressurised emerging technologies for fibrous structure engineering in drug delivery, regenerative medicine and theranostics

“…This is further revolutionising the practise of personalised medicine and opening new frontiers for novel technologies [5]. The ability to vary the structures of excipients during the engineering process offers exciting prospects due to the resulting impact on the functionality and performance of the final product or device [6][7][8]. In order to accomplish this, several engineering technologies have been deployed to achieve structural variations of the pharmaceutical dosage forms such as hydrogels [9][10][11][12], suspensions [13][14][15] and micelles [16][17][18][19][20].…”

“…Whilst these various structures have shown potential; the one structure that has shown most promise has been fibers. Fibrous or filamentous structures have gained significant attention in the last few decades in an array of remits ranging from drug delivery [21][22][23][24][25][26][27][28], tissue engineering [29][30][31][32][33][34][35][36], regenerative medicine [37][38][39][40][41][42][43][44] and even extending into the cosmetics industry [45,46] and electromagnetics and thermal management [8,[47][48][49][50][51][52].…”

Poly(p-phenylene benzobisoxazole) Fiber/Epoxy Composites Reinforced with Carbon Nanotubes and Graphene Oxide for Enhanced Interfacial Adhesion and Mechanical Strength

“…Because of various advantageous characteristics, such as outstanding mechanical properties, low density, and good thermal stability, poly­( p- phenylene benzo­bisoxazole) (PBO) fibers have been regarded as an ideal reinforcement for aerospace, defense, sports, transportation, energy management, and other areas. , To date, the main obstacle of exploiting PBO fibers is the poor interfacial compatibility and adhesion, which originates from the inherent smooth and chemical inert on the fiber surface. , As everyone knows, interfacial adhesion plays a crucial role in the load transfer nearby the interphase, the overall performance, and the service-life of composites. − The poor interfacial adhesion easily triggers the interfacial cracks and interlaminar failure under the transverse load. , In a word, the nonideal interfacial behaviors of PBO fibers composites make up one of the bottleneck problems during the development of advanced composites …”
