Problems solved by technology

[0006] Although sandwich composites provide the above-mentioned high flexural stiffness with a lower overall density for a lighter weight assembly, due to the desperate material for the outer skin walls and core materials) and their different thermal expansion coefficients introduce thermal stress. The thermal cycle performance of the sandwich composite is not optimal.

Embodiment Construction

[0010] The present invention has utility as an improved composite sandwich panel structure having two side sheets sandwiching an intermediate hollow structural core support matrix made of the same composite material as the top and bottom sheets to improve Thermal cycle performance and relief of formed part stress. The sandwich composite structure of the embodiment of the present invention is made of polypropylene, nylon, polycarbonate, polyethylene, acrylonitrile butadiene styrene (acrylonitrile butadienestyrene), polybutene, cross-linked polyethylene (polyethylene cross linked), poly Vinyl chloride, chlorinated polyvinyl chloride, polyvinylidene fluoride, and thermoplastic polymers containing any of the above block copolymers (block copolymers).

[0011] As used in the present invention, the term "same" applied to a type of polymer is intended to mean that there is a common monomeric subunit present in the majority in both polymers. It will be appreciated that some, but not ...

Abstract

The invention relates to an open area core with a chopped fiber reinforced skin. A process for forming a composite sandwich panel assembly is provided that includes positioning a top sheet and a bottom sheet on opposing sides of an open pore matrix core. The top sheet, bottom sheet, and core are exposed to a heat source with the application of a clamping pressure to the top and the bottom sheet. The heat source is then removed and the clamping pressure maintained for a period of time. The clamping pressure is removed when the top sheet, bottom sheet, and core have cooled and fused together. An assembly formed by such a process is also provided.

Description

[0001] This application is a divisional application of an invention patent application with a filing date of 2014.12.08, an application number of 201480073997.1, and an invention title of “Hollow Structural Core with Short Fiber Reinforced Surface”. [0002] related patent application [0003] This application claims priority to US Provisional Application Serial No. 61 / 912,749, filed December 6, 2013, the contents of which are hereby incorporated by reference. technical field [0004] The present invention relates generally to composite materials and in particular to a composite sandwich structure having side sheets and an intervening hollow structural core support made of the same composite material as the side sheets Matrix (open area core support matrix). Background technique [0005] Weight savings has been a major focus in automotive, transportation and logistics based industries in order to create more fuel efficient vehicles for both ground and air transportation. ...
