24 Panels

In June 2017, the Grenfell fire killed 72 people in a 24-story tower block in West London. 24 PANELS is an anthology comic to support the PTSD needs of the survivors. Curated by KIERON GILLEN (THE WICKED + THE DIVINE), it features 24 stories, each no longer than 24 panels. Half drawn from professional creators who volunteered their time and half drawn from open submissions, 24 PANELS is about community, hope, and (most of all) raising as much money as possible.

Results are present for part of a test program on 24S-T aluminum-alloy flat compression panels with hat-section stiffeners. The results show the effect of the relative dimensions of a panel on the buckling stress and average stress at maximum load. Comparative envelope curves are presented to provide some indication of the relative structural efficiencies of hat- and Z-stiffened panels having a ratio of stiffener thicknews to skin thickness of one.

Results are presented of a series of fatigue tests to study crack propagation and the resulting stress distributions in tension panels. The panels were all of the same general design, and configurations varied mainly in the relative amount of cross-sectional area in the skin, stiffeners, and flanges. The panels were constructed of 2024-T3 and 7075-T6 aluminum alloys. It was found that the average rate of crack growth was slower in panels made of 2024-T3 aluminum alloy than in panels made of 7075-T6 aluminum alloy. All cracks initiated in the skin, and the slowest crack growth was measured in configurations where the highest percentage of cross-sectional area was in the stiffeners. Strain-gage surveys were made to determine the redistribution of stress as the crack grew across the panels. As a crack approached a given point in the skin, the stress at that point increased rapidly. The stress in the stiffeners also increased as the crack approached the stiffeners. During the propagation of the crack the stress was not distributed uniformly in the remaining area.

Oil Palm Biomass for Composite Panels: Fundamentals, Processing, and Applications explains the preparation and utilization of oil palm biomass for advanced composite panel products. It introduces the fundamentals of oil palm biomass and wood-based panel products, including basic properties, durability, deterioration, and adhesives. It also includes in-depth information on processing and treatments organized by biomass type, covering oil palm trunk and lumber, veneer, empty fruit bunches (EFBs), oil palm fronds, and other sources. Additionally, this book focuses on specific composite panel applications, explaining the utilization of oil palm biomass in specific products. Finally, current policy, economic and environmental factors, and supply considerations are discussed. The information contained in Oil Palm Biomass for Composite Panels will be of interest to researchers, scientists and advanced students in bio-based materials, polymer science, composites, wood science, forestry, and biomass, as well as industrial scientists and product designers working with oil palm biomass, wood-based products, and sustainable materials. Presents the latest processing and treatment methods for oil palm resources that are organized by biomass type Explores state-of-the-art composite panel products, such as laminated veneer lumber, plywood, oriented strand board, particleboard, fiberboard and blockboard Includes detailed coverage of fundamental aspects, including properties, durability, adhesives, policy and supply
