Incorporating foam into slurry can improve its wall-supporting performance. However, the wall formation mechanism of under different conditions remains unclear. In this study, numerical simulations were conducted to investigate influence soil properties, composition, and pressure gradient on infiltration process effectiveness slurry, which was validated through laboratory experiments. The results indicate that in be divided three stages—infiltration, clogging, membrane formation. time...

This study attempts to improve mechanical and material properties by incorporating hybrid fillers of rice bran carbon (RBC) modified fumed silica (SiO 2 ). The composites solution‐polymerized styrene butadiene rubber (SSBR) filled with RBC SiO were prepared via a mixing method. effect on varying amounts SSBR is illustrated, the cure characteristics, thermal stability, friction, are measured. It was discovered that can be enhanced addition through testing. results show ‐doped filler exhibited...

Abstract Cellulose fibers were modified via aqueous silane‐graphene oxide (GO) coordination by flash drying and extrusion dispersion process. The adsorption of GO reduced the polarity cellulose fiber surface attenuated agglomeration effect between fibers, thus facilitating in rubber matrix. Adding 3‐aminopropylsilane oligomer (8150) incorporated active sites on thereby improving interfacial binding properties nano (CNFs) natural (NR). After blending CNFs with NR latex, high‐temperature...

ABSTRACT The hybrid of bamboo charcoal (BCC) and silica‐reinforced styrene‐butadiene rubber was prepared by a modified sol–gel method hydrolyzing tetraethoxysilane over an acid catalyst. fracture surface the samples after tensile test characterized field emission‐scanning electron microscopy. strength, storage modulus, hardness, friction coefficient, swelling were discussed based on with or without 3‐(methacryloxy) propyl trimethoxy silane modification. results showed that modulus clearly...

Traffic violation and the flexible changeable nature of pedestrians make it more difficult to predict pedestrian behavior or intention, which might be a potential safety hazard on road. Pedestrian motion state (such as walking standing) directly affects reflects its intention. In combination with other influencing factors, intention can predicted avoid unnecessary accidents. this paper, is treated non-rigid object, represented by set two-dimensional key points, movement point relative torso...

Trajectory prediction has received much attention recently, especially in autonomous driving. Many Proposed models generate multi-modal trajectories using a wide variety of frameworks for context representation and dynamic interaction modeling. But they can not estimate the intention target vehicle, predicted are explicable. Towards this end, we propose model to vehicle predict possible corresponding intention. We separate intentions long-term indicating future path short-term behavior...

열가소성 폴리우레탄(thermoplastic polyurethane, TPU)이 가지는 경제적, 환경적 문제를 해결함과 동시에 TPU 물성 개선을 위한 방안으로 TPU에 폐타이어 분말을 적용하였다. 사용된 폐타이어(waste tire rubber, WTR)는 폐타이어를 변안활성기계(metactivator)에 통과시킨 것으로, 열역학적으로 불안정하며 미세 균열 입자의 형태를 보이고, 가교결합은 끊어진 상태로 존재한다. 단순히 TPU와 WTR을 혼합한 복합체와 2-hydroxyethyl methacrylate와 dicumyl peroxide를 사용하여 가교를 형성시킨 복합체를 제조하였다. WTR의 구조를 FTIR로 관찰하고, 두 종류의 TPU/WTR DSC를 통해 유리전이온도(Tg)를 측정하였다. 가교로 개질된 복합체는 내수성, 내화학성이 크게 향상되었고, 극성 비양성자성 용매에서의 팽윤 특성 또한 우수하였다. 저장탄성률의 증가와 함께 영구압축 줄음률 향상되었다.

Styrene-butadiene rubber (SBR), reinforced with different contents of silica (with or without modification using silane coupling agents), was prepared by a modified sol-gel method involving hydrolyzation tetraethoxysilane over an acid catalyst.
